## NAME
    [File::DosGlob](https://www.chedong.com/phpMan.php/perldoc/File%3A%3ADosGlob/markdown) - DOS like globbing and then some

## SYNOPSIS
        require 5.004;

        # override [CORE::glob](https://www.chedong.com/phpMan.php/perldoc/CORE%3A%3Aglob/markdown) in current package
        use [File::DosGlob](https://www.chedong.com/phpMan.php/perldoc/File%3A%3ADosGlob/markdown) 'glob';

        # override [CORE::glob](https://www.chedong.com/phpMan.php/perldoc/CORE%3A%3Aglob/markdown) in ALL packages (use with extreme caution!)
        use [File::DosGlob](https://www.chedong.com/phpMan.php/perldoc/File%3A%3ADosGlob/markdown) 'GLOBAL_glob';

        @perlfiles = glob  "..\\pe?l/*.p?";
        print <..\\pe?l/*.p?>;

        # from the command line (overrides only in main::)
        > perl -[MFile::DosGlob](https://www.chedong.com/phpMan.php/perldoc/MFile%3A%3ADosGlob/markdown)=glob -e "print <../pe*/*p?>"

## DESCRIPTION
    A module that implements DOS-like globbing with a few enhancements. It is largely compatible
    with perlglob.exe (the M$ setargv.obj version) in all but one respect--it understands wildcards
    in directory components.

    For example, "<..\\l*b\\file/*glob.p?>" will work as expected (in that it will find something
    like '..\lib\File/DosGlob.pm' alright). Note that all path components are case-insensitive, and
    that backslashes and forward slashes are both accepted, and preserved. You may have to double
    the backslashes if you are putting them in literally, due to double-quotish parsing of the
    pattern by perl.

    Spaces in the argument delimit distinct patterns, so "glob('*.exe *.dll')" globs all filenames
    that end in ".exe" or ".dll". If you want to put in literal spaces in the glob pattern, you can
    escape them with either double quotes, or backslashes. e.g. "glob('c:/"Program
    Files"/*/*.dll')", or "glob('c:/Program\ Files/*/*.dll')". The argument is tokenized using
    "[Text::ParseWords::parse_line](https://www.chedong.com/phpMan.php/perldoc/Text%3A%3AParseWords%3A%3Aparseline/markdown)()", so see [Text::ParseWords](https://www.chedong.com/phpMan.php/perldoc/Text%3A%3AParseWords/markdown) for details of the quoting rules used.

    Extending it to csh patterns is left as an exercise to the reader.

## BUGS
    Should probably be built into the core, and needs to stop pandering to DOS habits. Needs a dose
    of optimization too.

## HISTORY
    *   Support for globally overriding glob() (GSAR 3-JUN-98)

    *   Scalar context, independent iterator context fixes (GSAR 15-SEP-97)

    *   A few dir-vs-file optimizations result in glob importation being 10 times faster than using
        perlglob.exe, and using perlglob.bat is only twice as slow as perlglob.exe (GSAR 28-MAY-97)

    *   Several cleanups prompted by lack of compatible perlglob.exe under Borland (GSAR 27-MAY-97)

    *   Initial version (GSAR 20-FEB-97)
