| 7347 | 2023 @deffn {Command} clear [options] pattern @dots{}\n\ |
| 3361 | 2024 Delete the names matching the given patterns from the symbol table. The\n\ |
| 2025 pattern may contain the following special characters:\n\ | |
| 4016 | 2026 \n\ |
| 3361 | 2027 @table @code\n\ |
| 2028 @item ?\n\ | |
| 2029 Match any single character.\n\ | |
| 668 | 2030 \n\ |
| 3361 | 2031 @item *\n\ |
| 2032 Match zero or more characters.\n\ | |
| 2033 \n\ | |
| 2034 @item [ @var{list} ]\n\ | |
| 2035 Match the list of characters specified by @var{list}. If the first\n\ | |
| 2036 character is @code{!} or @code{^}, match all characters except those\n\ | |
| 2037 specified by @var{list}. For example, the pattern @samp{[a-zA-Z]} will\n\ | |
| 2038 match all lower and upper case alphabetic characters.\n\ | |
| 2039 @end table\n\ | |
| 2040 \n\ | |
| 2041 For example, the command\n\ | |
| 593 | 2042 \n\ |
| 3361 | 2043 @example\n\ |
| 2044 clear foo b*r\n\ | |
| 2045 @end example\n\ | |
| 2046 \n\ | |
| 2047 @noindent\n\ | |
| 2048 clears the name @code{foo} and all names that begin with the letter\n\ | |
| 2049 @code{b} and end with the letter @code{r}.\n\ | |
| 668 | 2050 \n\ |
| 3361 | 2051 If @code{clear} is called without any arguments, all user-defined\n\ |
| 2052 variables (local and global) are cleared from the symbol table. If\n\ | |
| 2053 @code{clear} is called with at least one argument, only the visible\n\ | |
| 2054 names matching the arguments are cleared. For example, suppose you have\n\ | |
| 2055 defined a function @code{foo}, and then hidden it by performing the\n\ | |
| 2056 assignment @code{foo = 2}. Executing the command @kbd{clear foo} once\n\ | |
| 2057 will clear the variable definition and restore the definition of\n\ | |
| 2058 @code{foo} as a function. Executing @kbd{clear foo} a second time will\n\ | |
| 2059 clear the function definition.\n\ | |
| 2060 \n\ | |
| 7347 | 2061 The following options are available in both long and short form\n\ |
| 2062 @table @code\n\ | |
| 2063 @item -all, -a\n\ | |
| 2064 Clears all local and global user-defined variables and all functions\n\ | |
| 2065 from the symbol table.\n\ | |
| 2066 \n\ | |
| 2067 @item -exclusive, -x\n\ | |
| 2068 Clears the variables that don't match the following pattern.\n\ | |
| 2069 \n\ | |
| 2070 @item -functions, -f\n\ | |
| 2071 Clears the function names and the built-in symbols names.\n\ | |
| 2072 @item -global, -g\n\ | |
| 2073 Clears the global symbol names.\n\ | |
| 2074 @item -variables, -v\n\ | |
| 2075 Clears the local variable names.\n\ | |
