find2perl makes this easy. It takes the same arguments as the find command and produces a script for you. It comes with perl on unix, linux and Windows.
Running the command
find2perl /some/directory -name '*.gz' -exec gunzip {} \;
produces
#! /usr/bin/perl -w
eval 'exec /usr/bin/perl -S $0 ${1+"$@"}'
if 0; #$running_under_some_shell
use strict;
use File::Find ();
# Set the variable $File::Find::dont_use_nlink if you're using AFS,
# since AFS cheats.
# for the convenience of &wanted calls, including -eval statements:
use vars qw/*name *dir *prune/;
*name = *File::Find::name;
*dir = *File::Find::dir;
*prune = *File::Find::prune;
sub wanted;
sub doexec ($@);
use Cwd ();
my $cwd = Cwd::cwd();
# Traverse desired filesystems
File::Find::find({wanted => \&wanted}, '/some/directory');
exit;
sub wanted {
/^.*\.gz\z/s &&
doexec(0, 'gunzip','{}');
}
sub doexec ($@) {
my $ok = shift;
my @command = @_; # copy so we don't try to s/// aliases to consta
+nts
for my $word (@command)
{ $word =~ s#{}#$name#g }
if ($ok) {
my $old = select(STDOUT);
$| = 1;
print "@command";
select($old);
return 0 unless <STDIN> =~ /^y/;
}
chdir $cwd; #sigh
system @command;
chdir $File::Find::dir;
return !$?;
}
