STRMATCH(3)

NAME
strmatch - match shell file patterns

SYNOPSIS

DESCRIPTION
strmatch compares the string s with the shell pattern p and returns 1 for match and 0 otherwise. submatch does a leading substring match of the shell pattern p with the string s. If m is 0 then the match is minimal, otherwise a maximal match is done. A pointer to the first character after the matched substring is returned, 0 if there is no match.

Except for & and !, each shell pattern has an equivalent egrep(1) construct.

BUGS
An unbalanced terminates the top level pattern.
Nested and constructs are non-intuitive and are computationally intensive.
