There are several+ flavors of "glob" (various DOS globbers, BSD glob, POSIX glob) and there are differences and that sometimes matters a lot! For example some DOS globbers don't work with filenames with spaces in them!

Internally within my code, I don't use glob, preferring to open a directory and use grep{} with a regex to filter out what I want as shown below (note: file test operators can also be added to the grep, etc). This method is multi-platform and works with Perl 5.6 (even Win 98 ports). Independent of command line expansion issues (there is a good post about that already), this sort of thing happens all the time, e.g. I want to know the .backup files for my application in directory X.

Basically use glob() only when forced to do so.

#!/usr/bin/perl -w use strict; #print all files ending in .pl within C:/Temp directory my $dir = 'C:/Temp'; opendir (DIR, $dir) || die "couldn't open $dir"; my @files = grep {/\.pl$/}readdir DIR; print "@files";
