copied!<p><a href="http://www.freedesktop.org/wiki/Specifications" rel="nofollow noreferrer">http://www.freedesktop.org/wiki/Specifications</a> is probably a good place to start. I find these quite hard to follow most of the time, but sometimes you can figure it out. Specifically, the "Desktop Entry Specification".</p> <p>Also, I don't think you'll be able to use any aliases from <code>.bashrc</code>, at least not without writing some kind of wrapper script. I think it needs to be an executable file. Of course, you could just use the good old symlinks- to- same + what's- my- name trick...</p> <p>(Which, for reference, goes like this:</p> <ol> <li>Make a script which uses its own name as a parameter.</li> <li>Make symlinks to said script using the parameter values as the link names.)</li> </ol> <hr> <h1>Investigating...</h1> <p>Some casual investigation reveals that creating these is fairly simple if you use Nautilus, (at least the version I have):</p> <ol> <li>Bring up the context menu for some random file, and use "Open With"->"Open with Other Application".</li> <li>Unfold the "Use a custom command" and type in something like: <ol> <li><code>xterm -e 'bash -c "unzip -l %f; sleep 5"'</code></li> </ol></li> <li>This results in <ol> <li>the command being run (so don't type <code>rm -rf</code>)</li> <li>a file in <code>~/.local/share/applications/</code> called <code>xterm-usercreated.desktop</code></li> </ol></li> </ol> <p>Here at least, I get the follow file:</p> <pre><code>[Desktop Entry] Encoding=UTF-8 Name=xterm MimeType=application/zip; Exec=xterm -e 'bash -c "unzip -l %f; sleep 5"' %f Type=Application Terminal=false NoDisplay=true </code></pre> <p>4: Looking at the system xterm .desktop I find this:</p> <pre><code>[Desktop Entry] Type=Application Encoding=UTF-8 Name=XTerm GenericName= Comment=XTerm: terminal emulator for X Icon=/usr/share/pixmaps/xterm-color_32x32.xpm Exec=xterm Terminal=false Categories=X-Debian-Applications-Terminal-Emulators; </code></pre> <p>5: Editing the .usercreated.desktop file to this:</p> <pre><code>[Desktop Entry] Type=Application Encoding=UTF-8 Name=xtermz Exec=xterm -e 'bash -c "unzip -l %f; sleep 5"' %f Terminal=false Categories=X-Local-WTF </code></pre> <p>6: Run xdg-desktop-menu forceupdate --mode user</p> <p>7: "xtermz" now shows up in the list... Success!</p> <p>8: Yuck! This also makes it appear in the main menu, under "Other". Weird!</p> <hr> <h2>Some notes:</h2> <ul> <li>In my Debian/testing, <code>xdg-desktop-menu</code> and friends (notably <code>xdg-icon-resource</code>) live in the <code>xdg-utils</code> package.</li> <li>You should be able to create a <code>.desktop</code> file from scratch.</li> <li>You should be able to install the <code>.desktop</code> file using <code>xdg-desktop-menu install</code> blah blah</li> </ul>
