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)
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:
- FNM["CASEFOLD"]
-
Corresponds to the
FNM_CASEFOLD
flag as defined in
fnmatch(3).
- FNM["FILE_NAME"]
-
Corresponds to the
FNM_FILE_NAME
flag as defined in
fnmatch(3).
- FNM["LEADING_DIR"]
-
Corresponds to the
FNM_LEADING_DIR
flag as defined in
fnmatch(3).
- FNM["NOESCAPE"]
-
Corresponds to the
FNM_NOESCAPE
flag as defined in
fnmatch(3).
- FNM["PATHNAME"]
-
Corresponds to the
FNM_PATHNAME
flag as defined in
fnmatch(3).
- FNM["PERIOD"]
-
Corresponds to the
FNM_PERIOD
flag as defined in
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"
