fnmatch — compare a string against a filename wildcard
result = fnmatch(pattern, string, flags)
The fnmatch extension provides an AWK interface to the fnmatch(3) routine. It adds a single function named fnmatch(), one predefined variable (FNM_NOMATCH), and an array of flag values named FNM.
The first argument is the filename wildcard to match, the second is the filename string, and the third is either zero, or the bitwise OR of one or more of the flags in the FNM array.
The return value is zero on success, FNM_NOMATCH if the string did not match the pattern, or a different non-zero value if an error occurred.
The flags are follows:
Corresponds to the FNM_CASEFOLD flag as defined in fnmatch(3).
Corresponds to the FNM_FILE_NAME flag as defined in fnmatch(3).
Corresponds to the FNM_LEADING_DIR flag as defined in fnmatch(3).
Corresponds to the FNM_NOESCAPE flag as defined in fnmatch(3).
Corresponds to the FNM_PATHNAME flag as defined in fnmatch(3).
Corresponds to the FNM_PERIOD flag as defined in fnmatch(3).
Nothing prevents AWK code from changing the predefined variabale FNM_NOMATCH, but doing so may cause strange results.
@load "fnmatch" ... flags = or(FNM["PERIOD"], FNM["NOESCAPE"]) if (fnmatch("*.a", "foo.c", flags) == FNM_NOMATCH) print "no match"
