cool pieces of codes

How cute, it’s self-modifying code.

Just a small issue with the python example, if run as a script it will rename itself.

Python:

from os import listdir, rename, path
 
for i, name in enumerate(listdir(".")):
    rename(name, "pysolfc%d%s" % (i+1, path.splitext(name)[1]))

or, a bit too clever perhaps:

from os import listdir, rename, path
 
any(rename(name, "pysolfc%d%s" % (i+1, path.splitext(name)[1]))
    for i, name in enumerate(listdir(".")))

Python’s penalized by explicit import of subsystems (the number of “built-ins” is relatively small), and less powerful formatting. But three lines are three lines… ;-)

#!/usr/bin/ruby
 
require 'fileutils'
 
Dir.glob(ARGV[0]).each_with_index do |fn, i|
  FileUtils.mv(fn, File.join(File.dirname(fn), "pysol#{i+1}" + File.extname(fn)))
end

man rename

I haven’t done anything in perl in a while, but your post got me motivated ;-). So here’s a solution in perl:

#!/usr/bin/env perl
use warnings;
use strict;
 
my $i=1;
foreach $_ (@ARGV) {
    if( $_ =~ /(jpeg|jpg|png|gif)/ ) {
        rename($_, "pysolfc" . $i++ . ".$1");
    }
}

Yea, if you’re looking for the ultimate in renaming, you should check out zmv.

@smoon, nice, after seeing your solution I am wondering what led me to use printf. Seems the first thing that came to my mind wasn’t the most obvious ;-).
