    <p>My Linux system mounts some Samba shares, and some files are deposited by Windows users. The names of these files sometimes contain spaces and other undesirable characters. Changing these characters to hyphens <code>-</code> seems like a reasonable solution. Nothing else needs to be changed to handle these cleaned file names.</p> <p>A couple of questions,</p> <ul> <li><p>What other characters besides spaces, parenthesis should be translated?</p></li> <li><p>What other file attributes (besides file type (file/dir) and permissions) should be checked?</p></li> <li><p>Does Perl offer a <code>pushd</code>/<code>popd</code> equivalent, or is <code>chdir</code> a reasonable solution to traversing the directory tree?</p></li> </ul> <p>This is my Perl program</p> <pre><code>#!/bin/env perl use strict; use warnings; use File::Copy; #rename files, map characters (not allowed) to allowed characters #map [\s\(\)] to "-" my $verbose = 2; my $pat = "[\\s\\(\\)]"; sub clean { my ($name) = @_; my $name2 = $name; $name2 =~ s/$pat/\-/g; #skip when unchanged, collision return $name if (($name eq $name2) || -e $name2); #skip collisions print "r: $name\n" if ($verbose &gt; 2); rename($name, $name2); $name2; } sub pDir { my ($obj) = @_; return if (!-d $obj); return if (!opendir(DIR, $obj)); print "p: $obj/\n" if ($verbose &gt; 2); chdir($obj); foreach my $dir (readdir DIR) { next if ($dir =~ /^\.\.?$/); #skip ./, ../ pDir(clean($dir)); } close(DIR); chdir(".."); } sub main { foreach my $argv (@ARGV) { print "$argv/\n" if ($verbose &gt; 3); $argv = clean($argv); if (-d $argv) { pDir($argv); } } } &amp;main(); </code></pre> <p><em>These posts are related, but don't really address my questions,</em></p> <ul> <li><em>Use quotes: <a href="https://stackoverflow.com/questions/4285989/in-perl-how-to-handle-filenames-with-spaces">How to handle filenames with spaces?</a> (using other scripts, prefer removing need for quotes)</em></li> <li><em>File::Find <a href="https://stackoverflow.com/questions/5241692/perl-script-to-recursively-list-all-filename-in-directroy">perl script to recursively list all filename in directory</a> (yes, but I have other reasons)</em></li> <li><em>URL escaping: <a href="https://stackoverflow.com/questions/18241508/modifying-a-perl-script-which-has-an-error-handling-spaces-in-files">Modifying a Perl script which has an error handling spaces in files</a> (not urls)</em></li> <li><em>Quotemeta: <a href="https://stackoverflow.com/questions/1267669/how-can-i-safely-pass-a-filename-with-spaces-to-an-external-command-in-perl">How can I safely pass a filename with spaces to an external command in Perl?</a> (not urls)</em></li> </ul>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
