FNMATCH(3am) GNU Awk Extension Modules FNMATCH(3am)
NAME
fnmatch - compare a string against a filename wildcard
SYNOPSIS
@load "fnmatch"
result = fnmatch(pattern, string, flags)
DESCRIPTION
The fnmatch extension provides an AWK interface to the fnmatch(3) rou-
tine. It adds a single function named fnmatch(3), one predefined vari-
able (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:
FNM["CASEFOLD"]
Corresponds to the fnmatch(3).
FNM["FILE_NAME"]
Corresponds to the fnmatch(3).
FNM["LEADING_DIR"]
Corresponds to the FNM_LEADING_DIR flag as defined in
fnmatch(3).
FNM["NOESCAPE"]
Corresponds to the fnmatch(3).
FNM["PATHNAME"]
Corresponds to the fnmatch(3).
FNM["PERIOD"]
Corresponds to the fnmatch(3).
NOTES
Nothing prevents AWK code from changing the predefined variable
FNM_NOMATCH, but doing so may cause strange results.
EXAMPLE
@load "fnmatch"
...
flags = or(FNM["PERIOD"], FNM["NOESCAPE"])
if (fnmatch("*.a", "foo.c", flags) == FNM_NOMATCH)
print "no match"
