# NAME

File::DosGlob - DOS like globbing and then some

perlglob.bat - a more capable perlglob.exe replacement

# SYNOPSIS

        require 5.004;
        use File::DosGlob 'glob';  # override CORE::glob
        @perlfiles = glob  "..\\pe?l/*.p?";
        print <..\\pe?l/*.p?>;

        # from the command line
        > perl -MFile::DosGlob=glob -e "print <../pe*/*p?>"

        > perlglob ../pe*/*p?

# DESCRIPTION

A module that implements DOS-like globbing with a few enhancements. This file is also a portable replacement for perlglob.exe. 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.

When invoked as a program, it will print null-separated filenames to standard output.

While one may replace perlglob.exe with this, usage by overriding CORE::glob via importation should be much more efficient, because it avoids launching a separate process, and is therefore strongly recommended.

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

`glob()`

# BUGS

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

# HISTORY

- 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)
