WILDMAT(3)WILDMAT(3)NAMEwildmat - perform shell-style wildcard matching
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
special inside square brackets.
? Matches any single character.
* Matches any sequence of zero or more characters.
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.
This matches any character not in the set x...y, which is inter‐
preted as described above. For example, [^]-] matches any char‐
acter other than a close bracket or minus sign.

several times since then, most notably in comp.sources.misc in March,
Lars Mathiesen <email@example.com> 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 <firstname.lastname@example.org> added minus sign and close bracket han‐
dling in June, 1991.
