here's a script that Unix Guru Universe sent out today as a "good" script to use to rename a bunch of files with a simple regex as an ARG to determine how to rename. thought it may be fun to GOLF it =)

#!/usr/bin/perl # rename: renames files according to the expr given on the command lin +e. # The expr will usually be a 's' or 'y' command, but can be any valid # perl command if it makes sense. Takes a list of files to work on or # defaults to '*' in the current directory. # e.g. # rename 's/\.flip$/.flop/' # rename *.flip to *.flop # rename s/flip/flop/ # rename *flip* to *flop* # rename 's/^s\.(.*)/$1.X/' # switch sccs filenames around # rename 's/$/.orig/' */*.[ch] # add .orig to your source fil +es in */ # rename 'y/A-Z/a-z/' # lowercase all filenames in . # rename 'y/A-Z/a-z/ if -B' # same, but just binaries! # rename chop *~ # restore all ~ backup files use Getopt::Std; my ($subst, $name); if (!&getopts("nfq") || $#ARGV == -1) { die "Usage: rename [-fnq] <perl expression> [file file...] -f : Force the new filename even if it exists already -n : Just print what would happen, but don't do the command -q : Don't print the files as they are renamed e.g. : rename 's/\.c/.c.old/' * rename -q 'y/A-Z/a-z/' *\n"; } $subst = shift; # Get perl command to work on @ARGV = <*> if $#ARGV < 0; # Default to complete directory foreach $name (@ARGV) { $_ = $name; eval "$subst;"; die $@ if $@; next if -e $_ && !$opt_f; # Skip if the file exists if asked to. mext if $_ eq $name; if ($opt_n) { print "mv $name $_\n"; next; } print "mv $name $_\n" if !$opt_q; rename($name,$_) or warn "Can't rename $name to $_, $!\n"; }
