How do I set up preferred applications in Nautilus by file extension, rather than by mime type?
Solution 1:
You can use mimeopen
to set what application to use to open a file based upon it's extension.
Run mimeopen
followed by the file extension you want to change. For example, if I wanted to open .py
(python) files in Geany instead of Gedit I would run:
mimeopen .py
Which returns (on my system, this will depend slightly based on what software you have installed on your computer):
Please choose a default application for files of type text/x-python
1) Geany (geany)
2) notepad (wine-extension-txt)
3) gedit (gedit)
4) LibreOffice 4.0 Writer (libreoffice4.0-writer)
5) Other...
use application #
Inputting 1
and pressing Enter will open a blank .py
file in Geany and set all further .py
files to open in that editor.
If I put in 5
and press Enter I get the prompt:
use command:
In which case I can use a program's command to open whatever file type I am currently changing.
So I could have done:
mimeopen .py
Used 5
and put geany
as the command to get the same result:
You might notice that if you run mimeopen .py
again it will open a new .py
file in Geany (or whatever app you chose) instead of asking you what application to use. In that case you need to use the -a
handle, like this:
mimeopen -a .py
