This is to say, there is -no requirement for Bash to print a notice when it is started -interactively in the usual way. We made this exception because users -and standards expect shells not to print such messages. This -exception applies to any program that serves as a shell and that is -based primarily on Bash as opposed to other GNU software. - - Preamble - - The license agreements of most software companies try to keep users -at the mercy of those companies. By contrast, our General Public -License is intended to guarantee your freedom to share and change free -software--to make sure the software is free for all its users. The -General Public License applies to the Free Software Foundation's -software and to any other program whose authors commit to using it. -You can use it for your programs, too. - - When we speak of free software, we are referring to freedom, not -price. Specifically, the General Public License is designed to make -sure that you have the freedom to give away or sell copies of free -software, that you receive source code or can get it if you want it, -that you can change the software or use pieces of it in new free -programs; and that you know you can do these things. - - To protect your rights, we need to make restrictions that forbid -anyone to deny you these rights or to ask you to surrender the rights. -These restrictions translate to certain responsibilities for you if you -distribute copies of the software, or if you modify it. - - For example, if you distribute copies of a such a program, whether -gratis or for a fee, you must give the recipients all the rights that -you have. You must make sure that they, too, receive or can get the -source code. And you must tell them their rights. - - We protect your rights with two steps: (1) copyright the software, and -(2) offer you this license which gives you legal permission to copy, -distribute and/or modify the software. - - Also, for each author's protection and ours, we want to make certain -that everyone understands that there is no warranty for this free -software. If the software is modified by someone else and passed on, we -want its recipients to know that what they have is not the original, so -that any problems introduced by others will not reflect on the original -authors' reputations. - - The precise terms and conditions for copying, distribution and -modification follow. - - GNU GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License Agreement applies to any program or other work which -contains a notice placed by the copyright holder saying it may be -distributed under the terms of this General Public License. The -"Program", below, refers to any such program or work, and a "work based -on the Program" means either the Program or any work containing the -Program or a portion of it, either verbatim or with modifications. Each -licensee is addressed as "you". - - 1. You may copy and distribute verbatim copies of the Program's source -code as you receive it, in any medium, provided that you conspicuously and -appropriately publish on each copy an appropriate copyright notice and -disclaimer of warranty; keep intact all the notices that refer to this -General Public License and to the absence of any warranty; and give any -other recipients of the Program a copy of this General Public License -along with the Program. You may charge a fee for the physical act of -transferring a copy. - - 2. You may modify your copy or copies of the Program or any portion of -it, and copy and distribute such modifications under the terms of Paragraph -1 above, provided that you also do the following: - - a) cause the modified files to carry prominent notices stating that - you changed the files and the date of any change; and - - b) cause the whole of any work that you distribute or publish, that - in whole or in part contains the Program or any part thereof, either - with or without modifications, to be licensed at no charge to all - third parties under the terms of this General Public License (except - that you may choose to grant warranty protection to some or all - third parties, at your option). - - c) If the modified program normally reads commands interactively when - run, you must cause it, when started running for such interactive use - in the simplest and most usual way, to print or display an - announcement including an appropriate copyright notice and a notice - that there is no warranty (or else, saying that you provide a - warranty) and that users may redistribute the program under these - conditions, and telling the user how to view a copy of this General - Public License. - - d) You may charge a fee for the physical act of transferring a - copy, and you may at your option offer warranty protection in - exchange for a fee. - -Mere aggregation of another independent work with the Program (or its -derivative) on a volume of a storage or distribution medium does not bring -the other work under the scope of these terms. - - 3. You may copy and distribute the Program (or a portion or derivative of -it, under Paragraph 2) in object code or executable form under the terms of -Paragraphs 1 and 2 above provided that you also do one of the following: - - a) accompany it with the complete corresponding machine-readable - source code, which must be distributed under the terms of - Paragraphs 1 and 2 above; or, - - b) accompany it with a written offer, valid for at least three - years, to give any third party free (except for a nominal charge - for the cost of distribution) a complete machine-readable copy of the - corresponding source code, to be distributed under the terms of - Paragraphs 1 and 2 above; or, - - c) accompany it with the information you received as to where the - corresponding source code may be obtained. (This alternative is - allowed only for noncommercial distribution and only if you - received the program in object code or executable form alone.) - -Source code for a work means the preferred form of the work for making -modifications to it. For an executable file, complete source code means -all the source code for all modules it contains; but, as a special -exception, it need not include source code for modules which are standard -libraries that accompany the operating system on which the executable -file runs, or for standard header files or definitions files that -accompany that operating system. - - 4. You may not copy, modify, sublicense, distribute or transfer the -Program except as expressly provided under this General Public License. -Any attempt otherwise to copy, modify, sublicense, distribute or transfer -the Program is void, and will automatically terminate your rights to use -the Program under this License. However, parties who have received -copies, or rights to use copies, from you under this General Public -License will not have their licenses terminated so long as such parties -remain in full compliance. - - 5. By copying, distributing or modifying the Program (or any work based -on the Program) you indicate your acceptance of this license to do so, -and all its terms and conditions. - - 6. Each time you redistribute the Program (or any work based on the -Program), the recipient automatically receives a license from the original -licensor to copy, distribute or modify the Program subject to these -terms and conditions. You may not impose any further restrictions on the -recipients' exercise of the rights granted herein. - - 7. The Free Software Foundation may publish revised and/or new versions -of the General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - -Each version is given a distinguishing version number. If the Program -specifies a version number of the license which applies to it and "any -later version", you have the option of following the terms and conditions -either of that version or of any later version published by the Free -Software Foundation. If the Program does not specify a version number of -the license, you may choose any version ever published by the Free Software -Foundation. - - 8. If you wish to incorporate parts of the Program into other free -programs whose distribution conditions are different, write to the author -to ask for permission. For software which is copyrighted by the Free -Software Foundation, write to the Free Software Foundation; we sometimes -make exceptions for this. Our decision will be guided by the two goals -of preserving the free status of all derivatives of our free software and -of promoting the sharing and reuse of software generally. - - NO WARRANTY - - 9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY -FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN -OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES -PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED -OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF -MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS -TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE -PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, -REPAIR OR CORRECTION. - - 10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR -REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, -INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING -OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED -TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY -YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER -PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE -POSSIBILITY OF SUCH DAMAGES. - - END OF TERMS AND CONDITIONS - - Appendix: How to Apply These Terms to Your New Programs - - If you develop a new program, and you want it to be of the greatest -possible use to humanity, the best way to achieve this is to make it -free software which everyone can redistribute and change under these -terms. - - To do so, attach the following notices to the program. It is safest to -attach them to the start of each source file to most effectively convey -the exclusion of warranty; and each file should have at least the -"copyright" line and a pointer to where the full notice is found. - - <one line to give the program's name and a brief idea of what it does.> - Copyright (C) 19yy <name of author> - - This program is free software; you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation; either version 1, or (at your option) - any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the - GNU General Public License for more details. - - You should have received a copy of the GNU General Public License - along with this program; if not, write to the Free Software - Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. - -Also add information on how to contact you by electronic and paper mail. - -If the program is interactive, make it output a short notice like this -when it starts in an interactive mode: - - Gnomovision version 69, Copyright (C) 19xx name of author - Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. - This is free software, and you are welcome to redistribute it - under certain conditions; type `show c' for details. - -The hypothetical commands `show w' and `show c' should show the -appropriate parts of the General Public License. Of course, the -commands you use may be called something other than `show w' and `show -c'; they could even be mouse-clicks or menu items--whatever suits your -program. - -You should also get your employer (if you work as a programmer) or your -school, if any, to sign a "copyright disclaimer" for the program, if -necessary. Here a sample; alter the names: - - Yoyodyne, Inc., hereby disclaims all copyright interest in the - program `Gnomovision' (a program to direct compilers to make passes - at assemblers) written by James Hacker. - - <signature of Ty Coon>, 1 April 1989 - Ty Coon, President of Vice - -That's all there is to it!

Some functions use it as a repeat count, some -as a flag, and others to choose alternate behavior (refreshing the current -line as opposed to refreshing the screen, for example). Some choose to -ignore it. In general, if a -function uses the numeric argument as a repeat count, it should be able -to do something useful with both negative and positive arguments. -At the very least, it should be aware that it can be passed a -negative argument. - -@node Readline Variables -@section Readline Variables - -These variables are available to function writers. - -@deftypevar {char *} rl_line_buffer -This is the line gathered so far.

That is, it is not possible to accurately -expand a partial word without knowing all of the possible words -which make sense in that context. The Readline library provides -the user interface to completion, and two of the most common -completion functions: filename and username. For completing other types -of text, you must write your own completion function. This section -describes exactly what such functions must do, and provides an example. - -There are three major functions used to perform completion: - -@enumerate -@item -The user-interface function @code{rl_complete ()}. This function is -called with the same arguments as other Readline -functions intended for interactive use: @var{count} and -@var{invoking_key}. It isolates the word to be completed and calls -@code{completion_matches ()} to generate a list of possible completions. -It then either lists the possible completions, inserts the possible -completions, or actually performs the -completion, depending on which behavior is desired. - -@item -The internal function @code{completion_matches ()} uses your -@dfn{generator} function to generate the list of possible matches, and -then returns the array of these matches. You should place the address -of your generator function in @code{rl_completion_entry_function}. - -@item -The generator function is called repeatedly from -@code{completion_matches ()}, returning a string each time. The -arguments to the generator function are @var{text} and @var{state}. -@var{text} is the partial word to be completed. @var{state} is zero the -first time the function is called, allowing the generator to perform -any necessary initialization, and a positive non-zero integer for -each subsequent call. When the generator function returns -@code{(char *)NULL} this signals @code{completion_matches ()} that there are -no more possibilities left. Usually the generator function computes the -list of possible completions when @var{state} is zero, and returns them -one at a time on subsequent calls. Each string the generator function -returns as a match must be allocated with @code{malloc()}; Readline -frees the strings when it has finished with them. - -@end enumerate - -@deftypefun int rl_complete (int ignore, int invoking_key) -Complete the word at or before point. You have supplied the function -that does the initial simple matching selection algorithm (see -@code{completion_matches ()}). The default is to do filename completion. -@end deftypefun - -@deftypevar {Function *} rl_completion_entry_function -This is a pointer to the generator function for @code{completion_matches -()}.

The -Readline library gives you a set of commands for manipulating the text -as you type it in, allowing you to just fix your typo, and not forcing -you to retype the majority of the line. Using these editing commands, -you move the cursor to the place that needs correction, and delete or -insert the text of the corrections. Then, when you are satisfied with -the line, you simply press @key{RETURN}. You do not have to be at the -end of the line to press @key{RETURN}; the entire line is accepted -regardless of the location of the cursor within the line. - -@menu -* Readline Bare Essentials:: The least you need to know about Readline. -* Readline Movement Commands:: Moving about the input line. -* Readline Killing Commands:: How to delete text, and how to get it back! -* Readline Arguments:: Giving numeric arguments to commands. -@end menu - -@node Readline Bare Essentials -@subsection Readline Bare Essentials - -In order to enter characters into the line, simply type them. The typed -character appears where the cursor was, and then the cursor moves one -space to the right. If you mistype a character, you can use your -erase character to back up and delete the mistyped character. - -Sometimes you may miss typing a character that you wanted to type, and -not notice your error until you have typed several other characters. In -that case, you can type @key{C-b} to move the cursor to the left, and then -correct your mistake. Afterwards, you can move the cursor to the right -with @key{C-f}. - -When you add text in the middle of a line, you will notice that characters -to the right of the cursor are `pushed over' to make room for the text -that you have inserted. Likewise, when you delete text behind the cursor, -characters to the right of the cursor are `pulled back' to fill in the -blank space created by the removal of the text. A list of the basic bare -essentials for editing the text of an input line follows. - -@table @asis -@item @key{C-b} -Move back one character. -@item @key{C-f} -Move forward one character. -@item @key{DEL} -Delete the character to the left of the cursor. -@item @key{C-d} -Delete the character underneath the cursor. -@item @w{Printing characters} -Insert the character into the line at the cursor. -@item @key{C-_} -Undo the last thing that you did. You can undo all the way back to an -empty line. -@end table - -@node Readline Movement Commands -@subsection Readline Movement Commands - - -The above table describes the most basic possible keystrokes that you need -in order to do editing of the input line. For your convenience, many -other commands have been added in addition to @key{C-b}, @key{C-f}, -@key{C-d}, and @key{DEL}. Here are some commands for moving more rapidly -about the line. - -@table @key -@item C-a -Move to the start of the line. -@item C-e -Move to the end of the line. -@item M-f -Move forward a word. -@item M-b -Move backward a word. -@item C-l -Clear the screen, reprinting the current line at the top. -@end table - -Notice how @key{C-f} moves forward a character, while @key{M-f} moves -forward a word. It is a loose convention that control keystrokes -operate on characters while meta keystrokes operate on words. - -@node Readline Killing Commands -@subsection Readline Killing Commands - -@cindex Killing text -@cindex Yanking text - -@dfn{Killing} text means to delete the text from the line, but to save -it away for later use, usually by @dfn{yanking} (re-inserting) -it back into the line. -If the description for a command says that it `kills' text, then you can -be sure that you can get the text back in a different (or the same) -place later. - -When you use a kill command, the text is saved in a @dfn{kill-ring}. -Any number of consecutive kills save all of the killed text together, so -that when you yank it back, you get it all. The kill -ring is not line specific; the text that you killed on a previously -typed line is available to be yanked back later, when you are typing -another line. -@cindex Kill ring - -Here is the list of commands for killing text. - -@table @key -@item C-k -Kill the text from the current cursor position to the end of the line. - -@item M-d -Kill from the cursor to the end of the current word, or if between -words, to the end of the next word. - -@item M-DEL -Kill from the cursor the start of the previous word, or if between -words, to the start of the previous word. - -@item C-w -Kill from the cursor to the previous whitespace. This is different than -@key{M-DEL} because the word boundaries differ. - -@end table - -And, here is how to @dfn{yank} the text back into the line. Yanking -means to copy the most-recently-killed text from the kill buffer. - -@table @key -@item C-y -Yank the most recently killed text back into the buffer at the cursor. - -@item M-y -Rotate the kill-ring, and yank the new top. You can only do this if -the prior command is @key{C-y} or @key{M-y}. -@end table - -@node Readline Arguments -@subsection Readline Arguments - -You can pass numeric arguments to Readline commands. Sometimes the -argument acts as a repeat count, other times it is the @i{sign} of the -argument that is significant. If you pass a negative argument to a -command which normally acts in a forward direction, that command will -act in a backward direction. For example, to kill text back to the -start of the line, you might type @key{M--} @key{C-k}. - -The general way to pass numeric arguments to a command is to type meta -digits before the command. If the first `digit' you type is a minus -sign (@key{-}), then the sign of the argument will be negative. Once -you have typed one meta digit to get the argument started, you can type -the remainder of the digits, and then the command. For example, to give -the @key{C-d} command an argument of 10, you could type @key{M-1 0 C-d}. - - -@node Readline Init File -@section Readline Init File - -Although the Readline library comes with a set of Emacs-like -keybindings installed by default, -it is possible that you would like to use a different set -of keybindings. You can customize programs that use Readline by putting -commands in an @dfn{init} file in your home directory. The name of this -@ifset BashFeatures -file is taken from the value of the shell variable @code{INPUTRC}. If -@end ifset -@ifclear BashFeatures -file is taken from the value of the environment variable @code{INPUTRC}. If -@end ifclear -that variable is unset, the default is @file{~/.inputrc}. - -When a program which uses the Readline library starts up, the -init file is read, and the key bindings are set. - -In addition, the @code{C-x C-r} command re-reads this init file, thus -incorporating any changes that you might have made to it. - -@menu -* Readline Init Syntax:: Syntax for the commands in the inputrc file. -* Conditional Init Constructs:: Conditional key bindings in the inputrc file. -@end menu - -@node Readline Init Syntax -@subsection Readline Init Syntax - -There are only a few basic constructs allowed in the -Readline init file. Blank lines are ignored. -Lines beginning with a @key{#} are comments. -Lines beginning with a @key{$} indicate conditional -constructs (@pxref{Conditional Init Constructs}). Other lines -denote variable settings and key bindings. - -@table @asis -@item Variable Settings -You can change the state of a few variables in Readline by -using the @code{set} command within the init file. Here is how you -would specify that you wish to use @code{vi} line editing commands: - -@example -set editing-mode vi -@end example - -Right now, there are only a few variables which can be set; -so few, in fact, that we just list them here: - -@table @code - -@item editing-mode -@vindex editing-mode -The @code{editing-mode} variable controls which editing mode you are -using. By default, Readline starts up in Emacs editing mode, where -the keystrokes are most similar to Emacs. This variable can be -set to either @code{emacs} or @code{vi}. - -@item horizontal-scroll-mode -@vindex horizontal-scroll-mode -This variable can be set to either @code{On} or @code{Off}. Setting it -to @code{On} means that the text of the lines that you edit will scroll -horizontally on a single screen line when they are longer than the width -of the screen, instead of wrapping onto a new screen line. By default, -this variable is set to @code{Off}. - -@item mark-modified-lines -@vindex mark-modified-lines -This variable, when set to @code{On}, says to display an asterisk -(@samp{*}) at the start of history lines which have been modified. -This variable is @code{off} by default. - -@item bell-style -@vindex bell-style -Controls what happens when Readline wants to ring the terminal bell. -If set to @code{none}, Readline never rings the bell. If set to -@code{visible}, Readline uses a visible bell if one is available. -If set to @code{audible} (the default), Readline attempts to ring -the terminal's bell. - -@item comment-begin -@vindex comment-begin -The string to insert at the beginning of the line when the -@code{vi-comment} command is executed. The default value -is @code{"#"}. - -@item meta-flag -@vindex meta-flag -If set to @code{on}, Readline will enable eight-bit input (it -will not strip the eighth bit from the characters it reads), -regardless of what the terminal claims it can support. The -default value is @code{off}. - -@item convert-meta -@vindex convert-meta -If set to @code{on}, Readline will convert characters with the -eigth bit set to an ASCII key sequence by stripping the eigth -bit and prepending an @key{ESC} character, converting them to a -meta-prefixed key sequence. The default value is @code{on}. - -@item output-meta -@vindex output-meta -If set to @code{on}, Readline will display characters with the -eighth bit set directly rather than as a meta-prefixed escape -sequence. The default is @code{off}. - -@item completion-query-items -@vindex completion-query-items -The number of possible completions that determines when the user is -asked whether he wants to see the list of possibilities. If the -number of possible completions is greater than this value, -Readline will ask the user whether or not he wishes to view -them; otherwise, they are simply listed. The default limit is -@code{100}. - -@item keymap -@vindex keymap -Sets Readline's idea of the current keymap for key binding commands. -Acceptable @code{keymap} names are -@code{emacs}, -@code{emacs-standard}, -@code{emacs-meta}, -@code{emacs-ctlx}, -@code{vi}, -@code{vi-move}, -@code{vi-command}, and -@code{vi-insert}. -@code{vi} is equivalent to @code{vi-command}; @code{emacs} is -equivalent to @code{emacs-standard}. The default value is @code{emacs}. -The value of the @code{editing-mode} variable also affects the -default keymap. - -@item show-all-if-ambiguous -@vindex show-all-if-ambiguous -This alters the default behavior of the completion functions. If -set to @code{on}, -words which have more than one possible completion cause the -matches to be listed immediately instead of ringing the bell. -The default value is @code{off}. - -@item expand-tilde -@vindex expand-tilde -If set to @code{on}, tilde expansion is performed when Readline -attempts word completion. The default is @code{off}. - -@end table - -@item Key Bindings -The syntax for controlling key bindings in the init file is -simple. First you have to know the name of the command that you -want to change. The following pages contain tables of the command name, -the default keybinding, and a short description of what the command -does. - -Once you know the name of the command, simply place the name of the key -you wish to bind the command to, a colon, and then the name of the -command on a line in the init file. The name of the key -can be expressed in different ways, depending on which is most -comfortable for you. - -@table @asis -@item @w{@var{keyname}: @var{function-name} or @var{macro}} -@var{keyname} is the name of a key spelled out in English. For example: -@example -Control-u: universal-argument -Meta-Rubout: backward-kill-word -Control-o: ">&output" -@end example - -In the above example, @samp{C-u} is bound to the function -@code{universal-argument}, and @samp{C-o} is bound to run the macro -expressed on the right hand side (that is, to insert the text -@samp{>&output} into the line). - -@item @w{"@var{keyseq}": @var{function-name} or @var{macro}} -@var{keyseq} differs from @var{keyname} above in that strings -denoting an entire key sequence can be specified, by placing -the key sequence in double quotes. Some GNU Emacs style key -escapes can be used, as in the following example, but the -special character names are not recognized. - -@example -"\C-u": universal-argument -"\C-x\C-r": re-read-init-file -"\e[11~": "Function Key 1" -@end example - -In the above example, @samp{C-u} is bound to the function -@code{universal-argument} (just as it was in the first example), -@samp{C-x C-r} is bound to the function @code{re-read-init-file}, and -@samp{ESC [ 1 1 ~} is bound to insert the text @samp{Function Key 1}. -The following escape sequences are available when specifying key -sequences: - -@table @code -@item @kbd{\C-} -control prefix -@item @kbd{\M-} -meta prefix -@item @kbd{\e} -an escape character -@item @kbd{\\} -backslash -@item @kbd{\"} -@key{"} -@item @kbd{\'} -@key{'} -@end table - -When entering the text of a macro, single or double quotes should -be used to indicate a macro definition. Unquoted text -is assumed to be a function name. Backslash -will quote any character in the macro text, including @key{"} -and @key{'}. -For example, the following binding will make @kbd{C-x \} -insert a single @key{\} into the line: -@example -"\C-x\\": "\\" -@end example - -@end table -@end table - -@node Conditional Init Constructs -@subsection Conditional Init Constructs - -Readline implements a facility similar in spirit to the conditional -compilation features of the C preprocessor which allows key -bindings and variable settings to be performed as the result -of tests. There are three parser directives used. - -@ftable @code -@item $if -The @code{$if} construct allows bindings to be made based on the -editing mode, the terminal being used, or the application using -Readline. The text of the test extends to the end of the line; -no characters are required to isolate it. - -@table @code -@item mode -The @code{mode=} form of the @code{$if} directive is used to test -whether Readline is in @code{emacs} or @code{vi} mode. -This may be used in conjunction -with the @samp{set keymap} command, for instance, to set bindings in -the @code{emacs-standard} and @code{emacs-ctlx} keymaps only if -Readline is starting out in @code{emacs} mode. - -@item term -The @code{term=} form may be used to include terminal-specific -key bindings, perhaps to bind the key sequences output by the -terminal's function keys. The word on the right side of the -@samp{=} is tested against the full name of the terminal and the -portion of the terminal name before the first @samp{-}. This -allows @var{sun} to match both @var{sun} and @var{sun-cmd}, -for instance. - -@item application -The @var{application} construct is used to include -application-specific settings. Each program using the Readline -library sets the @var{application name}, and you can test for it. -This could be used to bind key sequences to functions useful for -a specific program. For instance, the following command adds a -key sequence that quotes the current or previous word in Bash: -@example -$if bash -# Quote the current or previous word -"\C-xq": "\eb\"\ef\"" -$endif -@end example -@end table - -@item $endif -This command, as you saw in the previous example, terminates an -@code{$if} command. - -@item $else -Commands in this branch of the @code{$if} directive are executed if -the test fails. -@end ftable - -@node Bindable Readline Commands -@section Bindable Readline Commands - -@menu -* Commands For Moving:: Moving about the line. -* Commands For History:: Getting at previous lines. -* Commands For Text:: Commands for changing text. -* Commands For Killing:: Commands for killing and yanking. -* Numeric Arguments:: Specifying numeric arguments, repeat counts. -* Commands For Completion:: Getting Readline to do the typing for you. -* Keyboard Macros:: Saving and re-executing typed characters -* Miscellaneous Commands:: Other miscellaneous commands. -@end menu - -@node Commands For Moving -@subsection Commands For Moving -@ftable @code -@item beginning-of-line (C-a) -Move to the start of the current line. - -@item end-of-line (C-e) -Move to the end of the line. - -@item forward-char (C-f) -Move forward a character. - -@item backward-char (C-b) -Move back a character. - -@item forward-word (M-f) -Move forward to the end of the next word.

If a numeric argument is supplied, -the output is formatted in such a way that it can be made part -of an @var{inputrc} file. - -@ifset BashFeatures -@item display-shell-version (C-x C-v) -Display version information about the current instance of Bash. - -@item shell-expand-line (M-C-e) -Expand the line the way the shell does when it reads it. This -performs alias and history expansion as well as all of the shell -word expansions. - -@item history-expand-line (M-^) -Perform history expansion on the current line. - -@item insert-last-argument (M-., M-_) -A synonym for @code{yank-last-arg}. - -@item operate-and-get-next (C-o) -Accept the current line for execution and fetch the next line -relative to the current line from the history for editing. Any -argument is ignored. - -@item emacs-editing-mode (C-e) -When in @code{vi} editing mode, this causes a switch back to -emacs editing mode, as if the command @code{set -o emacs} had -been executed. - -@end ifset - -@end ftable - -@node Readline vi Mode -@section Readline vi Mode - -While the Readline library does not have a full set of @code{vi} -editing functions, it does contain enough to allow simple editing -of the line. The Readline @code{vi} mode behaves as specified in -the Posix 1003.2 standard. - -@ifset BashFeatures -In order to switch interactively between @code{Emacs} and @code{Vi} -editing modes, use the @code{set -o emacs} and @code{set -o vi} -commands (@pxref{The Set Builtin}). -@end ifset -@ifclear BashFeatures -In order to switch interactively between @code{Emacs} and @code{Vi} -editing modes, use the command M-C-j (toggle-editing-mode). -@end ifclear -The Readline default is @code{emacs} mode. - -When you enter a line in @code{vi} mode, you are already placed in -`insertion' mode, as if you had typed an @samp{i}. Pressing @key{ESC} -switches you into `command' mode, where you can edit the text of the -line with the standard @code{vi} movement keys, move to previous -history lines with @samp{k}, and following lines with @samp{j}, and -so forth.
