Re^2: Need help with loops and 3 tables

No! Don't use unlink! perldoc -f unlink will tell you why:

unlink LIST
unlink Deletes a list of files. Returns the number of files success-
fully deleted.
$cnt = unlink 'a', 'b', 'c';
unlink @goners;
unlink <*.bak>;

Note: "unlink" will not delete directories unless you are supe-
ruser and the -U flag is supplied to Perl. Even if these con-
ditions are met, be warned that unlinking a directory can
inflict damage on your filesystem. Use "rmdir" instead.

If LIST is omitted, uses $_.

So long as you're not running with root permissions the underlying `unlink(2)` should fail with EPERM (per POSIX) if you try and unlink a directory. `$ perl -le 'mkdir "OHNOEZ"; unlink "OHNOEZ" or die "unlink: $!\n";rmdi +r "OHNOEZ"' unlink: Operation not permitted` [download] Your system's `rm` command's going to be making the same underlying `unlink(2)` call for the same arguments for that matter; so long as you're not running as root it's a rather spurious thing to worry about. The cake is a lie. The cake is a lie. The cake is a lie.	[reply] [d/l]
