Try this:

#!/usr/bin/perl -w foreach (@ARGV){ $name = $_ ; $name =~ s/_/-/; rename($_, $name); print "$_ renamed to $name\n"; } usage: *.zzz

Use File::Copy.

use File::Copy; use strict; my($sourcedir) = shift || die "No source dir"; opendir(DIR,"$sourcedir"); foreach (grep !/^\.\.?$/,readdir DIR) { if (/^(\S+)_(\S+)\.(\S+)$/) { if (move($_,"$1-$2.$3")) { print "Moved $_ to $1-$2.$3\n"; } else { print "Error moving $_ to $1-$2.$3\n"; } } }

#!/usr/bin/perl -w # rename all files with a certain extention in a directory use strict; my $dirname; $dirname = '/substitue_your_path_here'; opendir(DIR, $dirname) or die "Can't opendir $dirname: $!"; while ( defined (my $file = readdir DIR) ) { # ignore current and parent directory . and .. next if $file =~ /^\.\.?$/; my $new = $file; # substitute new file extension $new =~ s/\.old_extension$/\.new_extension/; rename($file,$new) }

You can use Rename files safely which will make sure that no files are erased in the process.

    [holli]: nice. i never thought of hosting a script on the site
    [LanX]: It's not a perfect solution, since it means invoking the monastery several times, but IMHO still better than hosting on another server
    [holli]: i'm surprised it even executes. the server sends text/plain AND a content-dispositio n header
    [holli]: this really really should not be executed as Javascript
    erix's head is getting content indisposed
    [holli]: maybe try a GET instead?
    [moritz]: I must say, when I was very active on perlmonks, I got really used to the markup and all the workflows
    [moritz]: and then I didn't post for a while, and then tried to answer a question. It nearly drove me nuts
    [moritz]: when you try to quote part of a question, you have to know/guess/reverse -engineer what kind of markup they used
