vgersh99 already answered your question but you might want to know why your code didn't work:

Well, s/\[// replaces an opening bracket with nothing (effectively deleting it) and the other substitution does the same with closing brackets. This is why only the brackets are removed, but not what they enclose.

vgersh99s code searches for an opening bracket, followed by any number of not-closing-bracket-characters, followed by a closing bracket and removes this.

I hope this helps.

WILDMAT(3)						     Library Functions Manual							WILDMAT(3)

NAME
wildmat - perform shell-style wildcard matching SYNOPSIS
int wildmat(text, pattern) char *text; char *pattern; DESCRIPTION
Wildmat is part of libinn (3). Wildmat compares the text against the pattern and returns non-zero if the pattern matches the text. The pattern is interpreted according to rules similar to shell filename wildcards, and not as a full regular expression such as those handled by the grep(1) family of programs or the regex(3) or regexp(3) set of routines. The pattern is interpreted as follows: x Turns off the special meaning of x and matches it directly; this is used mostly before a question mark or asterisk, and is not spe- cial inside square brackets. ? Matches any single character. * Matches any sequence of zero or more characters. [x...y] Matches any single character specified by the set x...y. A minus sign may be used to indicate a range of characters. That is, [0-5abc] is a shorthand for [012345abc]. More than one range may appear inside a character set; [0-9a-zA-Z._] matches almost all of the legal characters for a host name. The close bracket, ], may be used if it is the first character in the set. The minus sign, -, may be used if it is either the first or last character in the set. [^x...y] This matches any character not in the set x...y, which is interpreted as described above. For example, [^]-] matches any character other than a close bracket or minus sign. HISTORY
Written by Rich $alz <rsalz@uunet.uu.net> in 1986, and posted to Usenet several times since then, most notably in comp.sources.misc in March, 1991. Lars Mathiesen <thorinn@diku.dk> enhanced the multi-asterisk failure mode in early 1991. Rich and Lars increased the efficiency of star patterns and reposted it to comp.sources.misc in April, 1991. Robert Elz <kre@munnari.oz.au> added minus sign and close bracket handling in June, 1991. This is revision 1.10, dated 1992/04/03. SEE ALSO
