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 subtitles with periscope
  • Rename subtitles easily
  • Move files into a new folder
• 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 Print File action, which uses xfprint to print text files. 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 Action Dialog

On the first page, enter Search with Catfish in Name: and search in Description: Enter catfish %f 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 the system-search.svg icon was used).

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…
• Command: gnome-search-tool –path=%f
• File pattern: *
• Appears if selection contains: Directories

Note: For this action, you'll need to have gnome-search-tool installed, which is part of the gnome-utils package. This program also has a lot of other nice command-line options which you could use to create even more specialized actions.

• Name: Search files inside…
• 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: Extract here (bzip2)
• Command: tar xjf %n
• File pattern: *.tar.bz2;*.tbz2
• Appears if selection contains: Other Files

• Name: Extract here (zip)
• Command: unzip %f
• File pattern: *.zip
• Appears if selection contains: Other Files

• Name: Create tar.gz from folder
• Command: tar czvf %n.tar.gz %n
• File pattern: *
• Appears if selection contains: Directories

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.

• Name: Play with XMMS
• Command: xmms %F
• File pattern: *
• Appears if selection contains: Directories, Audio Files
• Name: Enqueue in XMMS
• Command: xmms -e %F
• File pattern: *
• Appears if selection contains: Directories, Audio Files

Hint: Works exactly the same with Audacious.

• Name: Burn with K3B
• Command: k3b --cdimage %f
• File pattern: *.iso
• Appears if selection contains: Other Files

• Name: View with GQview
• Command: gqview %f
• File pattern: *
• Appears if selection contains: Directories, Image Files

Note: This tip also works just as well with GThumb

• Name: To JPEG
• Command: convert %f -quality 75 %f.jpg
• File pattern: *.png
• Appears if selection contains: Image Files

Hint: `basename %f .png`.jpg (be careful–those are backticks) will strip the old .png extension off of the original filename.

• Name: Rotate Clockwise
• Command: for file in %F; do tempfile=$(mktemp); (jpegtran -copy all -rotate 90 $file > $tempfile); mv -f $tempfile $file; rm -f $tempfile; done
• File pattern: *.jpg;*.JPG;*.jpeg;*.JPEG
• Appears if selection contains: JPEG Image Files

Note: jpegtran is available as part of the libjpeg or libjpeg-progs packages of most distributions. Unlike using “convert”, the complicated loop structure is necessary with “jpegtran”: “jpegtran -rotate 90 -outfile %F %F” will produce a 0kb file.

Here an example how rotation can be scripted with “convert”.

• Name: Open terminal here
• Command: for f in %F; do if [ -d "$f" ]; then exo-open --working-directory "$f" --launch TerminalEmulator; elif [ -z "$default" ]; then default=1; exo-open --launch TerminalEmulator; fi done
• File pattern: *
• Appears if selection contains: any

Note: If non-directory files are selected, a terminal in the current directory will be opened Note: For each selected folder, a terminal on that folder is opened

• Name: Open a root terminal here
• Command: gksu “xfce4-terminal –default-working-directory=%f”
• File pattern: *
• Appears if selection contains: Directories

Note: You should rewrite the command with normal straight quotes.

• Name: Open a root Thunar here
• Command: gksu thunar %f
• File pattern: *
• Appears if selection contains: Directories

Note: Some distributions no longer include gksu. Use pkexec instead.

• Name: Edit as root
• Command: gksu put-your-favourite-text-editor-here %f
• File pattern: *
• Appears if selection contains: Text files

Note: You'll need to replace put-your-favourite-text-editor-here with your favourite text editor (e.g. mousepad or geany). Also, see previous note about gksu.

• Name: Create symlink
• Command: ln -s %f “%n (symlink)”
• File pattern: *
• Appears if selection contains: Directories, other files

For fans of the Windows “SendTo Extensions” power toy. This tip requires the xclip program, which you may need to install using your distribution's package manager.

• Name: Copy Pathname to Clipboard
• Description: Copies file's full pathname to the X PRIMARY selection
• Command: echo -n %f | xclip -i
• File pattern: *
• Appears if selection contains: any

• Name: Set as desktop background
• Command:

  xfconf-query -c xfce4-desktop -p /backdrop/screen0/monitor0/image-path -s %f

• File pattern: *
• Appears if selection contains: Image Files

• Name: Disk Usage
• Command: baobab %d
• File pattern: *
• Appears if selection contains: Tick all the boxes

Note: The idea is to get a visual picture of the current directory and any subdirectories. You could also use fsview or filelight, but the visuals are crisper in baobab.

• Name: Open in Terminal
• Command: xfce4-terminal -x nano %f
• File pattern: *
• Appearance Conditions: Text files

Since nano isn't a GUI app, you must start it in a terminal window.

• Name: Compare
• Command: meld %F
• File pattern: *

• Name: Export to PDF
• Command: unoconv -f pdf %F
• File pattern: *.doc;*.docx;*.odt;*.odp;*.pps;*.ppt;*.xls;*.xlsx;*.ods;*.pptx
• Appears if selection contains: Other files

You can go on, try man unoconv for details.

• Name: Download subtitles
• Command: periscope -l en %F && zenity –info –title “Done” –text “Subtitles downloaded successfully” || zenity –error –title “Error” –text “Subtitles not downloaded successfully”
• File pattern: *
• Appears if selection contains: Video Files

Note: You will need python-periscope package. Get it here. You'll also need zenity package. This command will try to get the English subtitles, change -l en to something else (fr, de, pt-br, …). You should rewrite the command with normal straight quotes.

• Name: Rename subtitles
