I'm pretty sure I've been schlepping this one along in my homedir as ~/bin/rename for well over two decades now that's genesis is about six years after the original.

#!/usr/bin/perl -w # # This script was developed by Robin Barker (Robin.Barker@npl.co.uk), # from Larry Wall's original script eg/rename from the perl source. # # This script is free software; you can redistribute it and/or modify + it # under the same terms as Perl itself. # # Larry(?)'s RCS header: # RCSfile: rename,v Revision: 4.1 Date: 92/08/07 17:20:30 # # $RCSfile: rename,v $$Revision: 1.5 $$Date: 1998/12/18 16:16:31 $ # # $Log: rename,v $ # Revision 1.5 1998/12/18 16:16:31 rmb1 # moved to perl/source # changed man documentation to POD # # Revision 1.4 1997/02/27 17:19:26 rmb1 # corrected usage string # # Revision 1.3 1997/02/27 16:39:07 rmb1 # added -v # # Revision 1.2 1997/02/27 16:15:40 rmb1 # *** empty log message *** # # Revision 1.1 1997/02/27 15:48:51 rmb1 # Initial revision # use strict; use Getopt::Long; Getopt::Long::Configure('bundling'); my ($verbose, $no_act, $force, $op); die "Usage: rename [-v] [-n] [-f] perlexpr [filenames]\n" unless GetOptions( 'v|verbose' => \$verbose, 'n|no-act' => \$no_act, 'f|force' => \$force, ) and $op = shift; $verbose++ if $no_act; if (!@ARGV) { print "reading filenames from STDIN\n" if $verbose; @ARGV = <STDIN>; chop(@ARGV); } for (@ARGV) { my $was = $_; eval $op; die $@ if $@; next if $was eq $_; # ignore quietly if (-e $_ and !$force) { warn "$was not renamed: $_ already exists\n"; } elsif ($no_act or rename $was, $_) { print "$was renamed as $_\n" if $verbose; } else { warn "Can't rename $was $_: $!\n"; } } __END__ =head1 NAME rename - renames multiple files =head1 SYNOPSIS B<rename> S<[ B<-v> ]> S<[ B<-n> ]> S<[ B<-f> ]> I<perlexpr> S<[ I<fil +es> ]> =head1 DESCRIPTION C<rename> renames the filenames supplied according to the rule specified as the first argument. The I<perlexpr> argument is a Perl expression which is expected to modify the C<$_> string in Perl for at least some of the filenames specified. If a given filename is not modified by the expression, it will not be renamed. If no filenames are given on the command line, filenames will be read via standard input. For example, to rename all files matching C<*.bak> to strip the extens +ion, you might say rename 's/\.bak$//' *.bak To translate uppercase names to lower, you'd use rename 'y/A-Z/a-z/' * =head1 OPTIONS =over 8 =item B<-v>, B<--verbose> Verbose: print names of files successfully renamed. =item B<-n>, B<--no-act> No Action: show what files would have been renamed. =item B<-f>, B<--force> Force: overwrite existing files. =back =head1 ENVIRONMENT No environment variables are used. =head1 AUTHOR Larry Wall =head1 SEE ALSO mv(1), perl(1) =head1 DIAGNOSTICS If you give an invalid Perl expression you'll get a syntax error. =head1 BUGS The original C<rename> did not check for the existence of target filen +ames, so had to be used with care. I hope I've fixed that (Robin Barker). =cut
