Re^2: Unix shell ls vs readdir

[jffry]

Do you mean use it like this?

#!/usr/bin/perl -w

use strict;
use warnings;
use File::Find;

my @inits;

sub wanted {
    if (-l $_ && (readlink("$_") =~ /tomcat/)) {
        push @inits,  $_ ;
    }
}

find(\&wanted, '/etc/rc.d/init.d');

print join("\n", @inits);

I'm not really seeing what I'm gaining (aside from exposure to a very useful module). It seems like overkill, and I can't determine how to prevent it from recursively going into any subdirectories. The $options{'bydepth'} doesn't seem to do that from what I can understand of the docs.

If you're looking for files within a single known directory, File::Find (or the recurse method of Path::Class::Dir) will be of little value to you. Their purpose is to call a subroutine for every file under a certain point. Any filtering must be done inside your subroutine.

Options controlling depth-first or breadth-first processing of the directory tree will only effect order. No filtering would be implied.
