Re: Perl List files in directory

In addition to the others, you might also try not to reinvent the wheel. Whenever you need to search files, the 1st recommandation should be File::Find. In your case

use File::Find;

find({wanted => sub {-f and print "file = $_\n"},follow => 1},'.');

already does what you intend to do in a shorter, easier readable, more maintainable and much less errorprone way.

1st recommandation should be File::Find. In your case Are you sure about that? Because that doesn't have /opt/tmp or @files My first recommendation is always File::Find::Rule `use File::Find::Rule qw/ rule find /; my @files = find( file => maxdepth => 1, ascii => in => '/opt/tmp' );` [download]	[reply] [d/l]

O.K., you'd have to change `'.'` from my snippet to `'/opt'` or `'/opt/tmp'` or `$dir` to work it on other than current dir. Whether you use File::Find or File::Find::Rule is more a matter of taste. The maintainer of the module describes it as a is a friendlier interface to File::Find :-). Greetings, Janek Schleicher	[reply] [d/l] [select]

O.K., you'd have to change ... But where is the @files? :) Whether you use File::Find or File::Find::Rule is more a matter of taste. :) Hmm, @files? There is nothing like @files in File::Find docs ... OTOH File::Find::Rules shows a @files Its more than a matter of taste, File::Find::Rules is much much more memorable ... and friendly to noobs File::Find::Rules is like cake (sweet), where File::Find is like raw flour	[reply]

... already does what you intend... All three of the OP's examples don't descend into subdirs, this one does. Also, this code doesn't show which subdir the file was found in, so you'd probably want something like this instead: `find({wanted => sub {-f and print "file = $File::Find::name\n"},follow => 1},"/opt/tmp");`	[reply] [d/l]
