in reply to Traversing SubDir and Execute Unix Command

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 {} \;


#! /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 $File::Find::dir; return !$?; }
