* shexp.h: Defines and prototypes for shell exp. match routines
|
||
|
|
*
|
||
|
|
*
|
||
|
|
* This routine will match a string with a shell expression. The expressions
|
||
|
|
* accepted are based loosely on the expressions accepted by zsh.
|
||
|
|
*
|
||
|
|
* o * matches anything
|
||
|
|
* o ? matches one character
|
||
|
|
* o \ will escape a special character
|
||
|
|
* o $ matches the end of the string
|
||
|
|
* o [abc] matches one occurence of a, b, or c. The only character that needs
|
||
|
|
* to be escaped in this is ], all others are not special.
|
||
|
|
* o [a-z] matches any character between a and z
|
||
|
|
* o [^az] matches any character except a or z
|
||
|
|
* o ~ followed by another shell expression will remove any pattern
|
||
|
|
* matching the shell expression from the match list
|
||
|
|
* o (foo|bar) will match either the substring foo, or the substring bar.
|
||
|
|
* These can be shell expressions as well.
|
||
|
|
*
|
||
|
|
* The public interface to these routines is documented below.
