`die "$file does not exist!\n" unless -e $file; my @perms; push @perms, 'read' if -r $file; push @perms, 'write' if -w $file; push @perms, 'execute' if -x $file; print @perms ? "You have @perms perms\n" : "You got zip\n";` [download] cheers tachyon	[reply] [d/l]

Looks like you just did this tyke's homework. Bad Tachyon. ------------------------------------- Nothing is too wonderful to be true -- Michael Faraday	[reply] [d/l]

Actually he has since added a clarification that places him on Win32, so he probably really wants Dave Roth's Win32::Perms cheers tachyon	[reply]

Also a good place to introduce `_` even if it's not saving much here (discussed in JediWizard's perldoc.com link; _ is a hard thing to search for). `die "$file does not exist!\n" unless -e $file; my @perms; push @perms, 'read' if -r _; push @perms, 'write' if -w _; push @perms, 'execute' if -x _; if ( @perms ) { printf "You have %s perms\n", join(", ", @perms); } else { print "You got zip\n"; }` [download]	[reply] [d/l] [select]

In solving this problem for my Perl 101 class, I used the file test operators. ---- I Go Back to Sleep, Now. OGB	[reply]

You can be a little more detailed or link me to a node or page I can look at this? I have no idea what to even search for and I searched "file test operators". Thanks	[reply]

You'll need to quote that file path in the command line usage you want. Otherwise it will be broken on spaces. After Compline, Zaxo	[reply]
