perlfaq8#How can I convert my shell script to perl?

To do it perfectly you should learn perl and port your bash script:

• perlintro
• http://learn.perl.org
• http://perldoc.perl.org
• The tutorials section of this site

It's easy! Just use magic like so:

#!/usr/bin/perl

use strict;
use warnings;
# ^^ part of every spell

system("/path/to/script");

Wow! It really is that easy! Now just skip past this unobtrusive black box below if you like the simplicity...

I wrote a much better translator. It's self-contained:

#!/usr/bin/perl

use strict;
use warnings;

my $pipe;
open $pipe, '|-', '/bin/sh';
while (<DATA>) {
    print $pipe $_;
}
close $pipe;

__DATA__
echo "hello world"

for i in 1 2 3 4; do
  printf "this is iteration %d of the loop\n" $i
done
