copied!<p>The Perl snippet is intriguing, and since Perl is present in most Linux distros, quite useful, but...It doesn't do the job completely. Specifically, there is a problem in translating the URL/URI format from UTF-8 into path Unicode. Let me give an example of the problem. The original URI may be:</p> <pre><code>file:///home/username/Music/Jean-Michel%20Jarre/M%C3%A9tamorphoses/01%20-%20Je%20me%20souviens.mp3 </code></pre> <p>The corresponding path would be:</p> <pre><code>/home/username/Music/Jean-Michel Jarre/Métamorphoses/01 - Je me souviens.mp3 </code></pre> <p><code>%20</code> became space, <code>%C3%A9</code> became 'é'. Is there a Linux command, bash feature, or Perl script that can handle this transformation, or do I have to write a humongous series of sed substring substitutions? What about the reverse transformation, from path to URL/URI?</p> <p>(Follow-up)</p> <p>Looking at <a href="http://search.cpan.org/~gaas/URI-1.54/URI.pm" rel="nofollow noreferrer">http://search.cpan.org/~gaas/URI-1.54/URI.pm</a>, I first saw the as_iri method, but that was apparently missing from my Linux (or is not applicable, somehow). Turns out the solution is to replace the "->path" part with "->file". You can then break that further down using basename and dirname, etc. The solution is thus:</p> <pre><code>path=$( echo "$url" | perl -MURI -le 'chomp($url = <>); print URI->new($url)->file' ) </code></pre> <p>Oddly, using "->dir" instead of "->file" does NOT extract the directory part: rather, it formats the URI so it can be used as an argument to mkdir and the like.</p> <p>(Further follow-up)</p> <p>Any reason why the line cannot be shortened to this?</p> <pre><code>path=$( echo "$url" | perl -MURI -le 'print URI->new(<>)->file' ) </code></pre>
