add a script to the default applications list in gnome

My previous post explains how to use a script to open vim in the terminal. I used a work-around method to set the script as the default editor for plain text files. With a bit of fiddling I added the script to the list of preferred applications:


Firstly create a new .desktop file for our script in our ~/.local/share/applications directory:
cd ~/.local/share/applications
vim /vim-gnome.desktop
Insert the following contents. Remember to replace '/PATH/TO/vim-gnome with the path to where you have the script saved. Also if you have a custom icon replace '/PATH/TO/vim.svg' with the path to your icon.

 Save the file.

~/.local/share/applications/vim-gnome.desktop is then referenced in ~/.local/share/applications/defaults.list, with:
cd ~/.local/share/applications
echo "text/plain=vim-gnome.desktop" >> defaults.list
That's it. You might need to restart nautilus or log out of gnome to see the change, I don't remember.

If you have made the changes correctly you should now see a new 'Vim Text Editor' entry in your Accessories menu, in your file properties dialog under the 'Open with' tab and in your context menu in Nautilus:


script to use terminal vim as default gnome editor http://goo.gl/OxAtC

Set terminal vim as the default editor instead of using one of the gui vims.

1. Create script:
vim vim-gnome
2. Script contents:
#!/bin/sh
ARGS="$@"
gnome-terminal -t "" -e "vim $ARGS"
3. Write buffer to file and close:
:wq
4. Make script executable:
chmod +x vim-gnome
5. Copy script to scripts directory (if you use one) eg.:
cp vim-gnome /home/lxtips/Dropbox/bin/
6. Set it as the default editor (in Ubuntu) right click the file in nautilus (ie. .bashrc) and select Properties > Open With.


7. Click Add > 'Use a custom command' and add the path to the script for example:
/home/lxtips/Dropbox/bin/vim-gnome
Repeat steps 6 and 7 for any other file types that still revert to the previous default editor.

8. Use an alternate gnome-terminal custom color scheme like the one below to match your favorite vim color scheme. If anyone knows how I might get gnome-terminal to replicate bolded text This is my attempt at Desert:

disable gnome-terminal close window warning dialog in gconf

gnome-terminal warns me if I try to close it while it is running something or logged in as root. A useful measure but also a bit annoying depending on your terminal habits. To disable the warning:


  1. Alt+F2 for the run dialog. Type 'gconf-editor' and hit enter.
  2. Navigate to apps > gnome-terminal > global.
  3. Uncheck 'confirm-window-close'.
  4. Close gconf-editor.
