| 7347 | 2111 @deffn {Command} clear [options] pattern @dots{}\n\ |
| 3361 | 2112 Delete the names matching the given patterns from the symbol table. The\n\ |
| 2113 pattern may contain the following special characters:\n\ | |
| 4016 | 2114 \n\ |
| 3361 | 2115 @table @code\n\ |
| 2116 @item ?\n\ | |
| 2117 Match any single character.\n\ | |
| 668 | 2118 \n\ |
| 3361 | 2119 @item *\n\ |
| 2120 Match zero or more characters.\n\ | |
| 2121 \n\ | |
| 2122 @item [ @var{list} ]\n\ | |
| 2123 Match the list of characters specified by @var{list}. If the first\n\ | |
| 2124 character is @code{!} or @code{^}, match all characters except those\n\ | |
| 2125 specified by @var{list}. For example, the pattern @samp{[a-zA-Z]} will\n\ | |
| 2126 match all lower and upper case alphabetic characters.\n\ | |
| 2127 @end table\n\ | |
| 2128 \n\ | |
| 2129 For example, the command\n\ | |
| 593 | 2130 \n\ |
| 3361 | 2131 @example\n\ |
| 2132 clear foo b*r\n\ | |
| 2133 @end example\n\ | |
| 2134 \n\ | |
| 2135 @noindent\n\ | |
| 2136 clears the name @code{foo} and all names that begin with the letter\n\ | |
| 2137 @code{b} and end with the letter @code{r}.\n\ | |
| 668 | 2138 \n\ |
| 3361 | 2139 If @code{clear} is called without any arguments, all user-defined\n\ |
| 2140 variables (local and global) are cleared from the symbol table. If\n\ | |
| 2141 @code{clear} is called with at least one argument, only the visible\n\ | |
| 2142 names matching the arguments are cleared. For example, suppose you have\n\ | |
| 2143 defined a function @code{foo}, and then hidden it by performing the\n\ | |
| 2144 assignment @code{foo = 2}. Executing the command @kbd{clear foo} once\n\ | |
| 2145 will clear the variable definition and restore the definition of\n\ | |
| 2146 @code{foo} as a function. Executing @kbd{clear foo} a second time will\n\ | |
| 2147 clear the function definition.\n\ | |
| 2148 \n\ | |
| 7347 | 2149 The following options are available in both long and short form\n\ |
| 2150 @table @code\n\ | |
| 2151 @item -all, -a\n\ | |
| 2152 Clears all local and global user-defined variables and all functions\n\ | |
| 2153 from the symbol table.\n\ | |
| 2154 \n\ | |
| 2155 @item -exclusive, -x\n\ | |
| 2156 Clears the variables that don't match the following pattern.\n\ | |
| 2157 \n\ | |
| 2158 @item -functions, -f\n\ | |
| 2159 Clears the function names and the built-in symbols names.\n\ | |
| 2160 @item -global, -g\n\ | |
| 2161 Clears the global symbol names.\n\ | |
| 2162 @item -variables, -v\n\ | |
