[FNMATCH(3am)](https://www.chedong.com/phpMan.php/man/FNMATCH/3am/markdown)                          GNU Awk Extension Modules                         [FNMATCH(3am)](https://www.chedong.com/phpMan.php/man/FNMATCH/3am/markdown)



## 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)](https://www.chedong.com/phpMan.php/man/fnmatch/3/markdown) 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)](https://www.chedong.com/phpMan.php/man/fnmatch/3/markdown).

       **FNM["FILE**___**NAME"]**
              Corresponds to the **FNM**___**FILE**___**NAME** flag as defined in [_fnmatch_(3)](https://www.chedong.com/phpMan.php/man/fnmatch/3/markdown).

       **FNM["LEADING**___**DIR"]**
              Corresponds to the **FNM**___**LEADING**___**DIR** flag as defined in [_fnmatch_(3)](https://www.chedong.com/phpMan.php/man/fnmatch/3/markdown).

### FNM["NOESCAPE"]
              Corresponds to the **FNM**___**NOESCAPE** flag as defined in [_fnmatch_(3)](https://www.chedong.com/phpMan.php/man/fnmatch/3/markdown).

### FNM["PATHNAME"]
              Corresponds to the **FNM**___**PATHNAME** flag as defined in [_fnmatch_(3)](https://www.chedong.com/phpMan.php/man/fnmatch/3/markdown).

### FNM["PERIOD"]
              Corresponds to the **FNM**___**PERIOD** flag as defined in [_fnmatch_(3)](https://www.chedong.com/phpMan.php/man/fnmatch/3/markdown).

## 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"
