If the file names are of the same length, you can just walk over them character by character and keep only those that are different.
#!/usr/bin/perl use warnings; use strict; my @files = qw( hhk_1sss-(hello).txt hhk_2abc-(hello).txt hhk_3xyz-(hello).txt ); my @short = @files; my $pos = 0; my $file = shift @short; while ($pos < length $file and '.' ne substr $file, $pos, 1) { my $char = substr $file, $pos, 1; if (@short == grep $char eq substr($_, $pos, 1), @short) { substr $_, $pos, 1, q() for $file, @short; } else { $pos++; } } unshift @short, $file; while (@files) { my $old = shift @files; my $new = shift @short; print "rename $old $new\n"; }

[davido]: I am not finding closing STDIN to be an adequate means of making getlogin return undef.
[Corion]: Maybe doing a double-fork (daemonizing) can make go that information away, but maybe not
[Corion]: But I think my knowledge of unix/Linux datastructures is several decades out of date, so I don't really know what information it keeps on processes
[oiskuu]: The useful bits that relate to your process can be found under /proc/self. What information are you thinking of? Tty name?
[tye]: I just daemonized and getlogin() still knew who I had been.
[tye]: perhaps loginuid ? Not that I concede that something not being in /proc means it is not useful.
