Thunar allows users to add custom actions to the file and folder context menus (by the use of the thunar-uca plugin, part of the Thunar distribution, in the plugins/ subdirectory). You can set up new actions in the Custom Actions dialog, available via the Configure custom actions... item in the Edit menu.

This page serves as an introduction to the Custom Actions plugin, and includes a list of useful examples.

• Adding a Custom Action
• Using mnemonics to open Custom Actions
• Examples
  • Search files with catfish
  • Work with archives (tar, gzip, etc)
  • Play/Enqueue music files
  • Convert PNGs to JPEGs
  • Rotate JPEGs
  • Open terminal here
  • Open root terminal here
  • Open thunar as root here
  • Edit file as root
  • Create a symbolic link
  • Create a hardlink
  • View disk usage of the current directory
  • Open file in terminal text editor
  • Compare selected files/directories
  • Change OpenDocument-supported formats
  • Download video subtitles
  • Rename subtitles easily
  • Move files into a new folder
  • Create Shared Thumbnails
  • Use 'bulk rename' on a single file
  • Trust multiple desktop files at once
• List of assorted custom actions (from Ubuntu documentation)

This section provides a step-by-step introduction to the Custom Actions plugin, demonstrating how to add a simple action. We start by opening the Custom Actions dialog as explained above. In the dialog, click on the first button in the list of buttons (the one labeled with the +). The Create Action dialog will appear, as shown in the screenshot below.

Create Custom Action Dialog

On the first page, enter Create symlink in Name: Enter ln -Ts %f %n“ (link)” for the Command: (the %f will be replaced with the path to the selected file, as explained in the dialog), and select an icon by clicking Icon: (in the screenshot emblem-symbolic-link was used).

Optionally, you can specify a Submenu:, in order to group multiple custom actions into the same menu.

  cmd "foo %f bar" (wrong) ->; cmd "foo "%f" bar" (correct)

  cmd "foo %f bar" (wrong) ->; f=%f; cmd "foo $f bar" (correct)

  for f in %F; do cmd "foo $f bar"; done

Now, continue with the second page (the Appearance Conditions page).

We want to create an action that is only applicable to folders, so select the Folders options and unselect the options for the other file types. Next you can specify a File Pattern to display the action only for text files that match a certain pattern. In the example, we set the file pattern to * (which matches all filenames) to indicate that the action should be displayed for all folders.

That's all. Click OK to close the Create Action dialog. The new action, labeled Search with Catfish will appear in the Custom Actions list.

Now close the Custom Actions dialog, select a folder in Thunar and open the context menu (right-click on the file icon). The newly created Search with Catfish action will appear in the context menu, as shown in the screenshot below.

When you create a Thunar Custom Action you can set the name with an underscore “_” before a letter to use it as mnemonic. When you right click in a Thunar view, you can type the letter to access your custom action.

Here are a few useful examples of custom actions. Feel free to extend this list.

• Name: Search files in folder
• Command: catfish %f
• File pattern: *
• Appears if selection contains: Directories

Note: For this action, you'll need to have catfish installed, which is part of the catfish package.

• Name: Create tar.gz from folder

Hint: You may prefer the Thunar Archive Plugin, which does pretty much the same thing with less manual setup required on your part. It's either included with your distribution (in the case of Xubuntu), or available as a separate package (thunar-archive-plugin in Debian Etch). You might also need the xarchiver or “squeeze” package for things to work quite right.
