Excerpt from the man page of ksh:

${parameter#pattern}
${parameter##pattern}

If the shell pattern matches the beginning of the value of parame-
ter, then the value of this expansion is the value of the parameter
with the matched portion deleted. Otherwise the value of this
parameter is substituted. In the first form the smallest matching
pattern is deleted and in the second form the largest matching pat-
tern is deleted. When parameter is @, *, or an array variable with
subscript @ or *, the substring operation is applied to each ele-
ment in turn.

${parameter%pattern}
${parameter%%pattern}

If the shell pattern matches the end of the value of parameter,
then the value of this expansion is the value of the parameter with
the matched part deleted. Otherwise substitute the value of parame-
ter. In the first form the smallest matching pattern is deleted,
and in the second form the largest matching pattern is deleted.
When parameter is @, *, or an array variable with subscript @ or *,
the substring operation is applied to each element in turn.

tcl_stringcasematch

Tcl_StringMatch(3)					      Tcl Library Procedures						Tcl_StringMatch(3)

__________________________________________________________________________________________________________________________________________________

NAME

       Tcl_StringMatch, Tcl_StringCaseMatch - test whether a string matches a pattern

SYNOPSIS

       #include <tcl.h>

       int
       Tcl_StringMatch(string, pattern)

       int
       Tcl_StringCaseMatch(string, pattern, nocase)

ARGUMENTS

       char	    *string	       (in)	 String to test.

       char	    *pattern	       (in)	 Pattern to match against string.  May contain special characters from the set *?[].

       int	    nocase	       (in)	 Specifies whether the match should be done case-sensitive (0) or case-insensitive (1).
_________________________________________________________________

DESCRIPTION

       This  utility  procedure  determines  whether  a  string  matches  a given pattern.  If it does, then Tcl_StringMatch returns 1.  Otherwise
       Tcl_StringMatch returns 0.  The algorithm used for matching is the same algorithm used in the ``string match'' Tcl command and  is  similar
       to the algorithm used by the C-shell for file name matching;  see the Tcl manual entry for details.					   |

       In  Tcl_StringCaseMatch,  the algorithm is the same, but you have the option to make the matching case-insensitive.  If you choose this (by |
       passing nocase as 1), then the string and pattern are essentially matched in the lower case.

KEYWORDS

       match, pattern, string
