[SOLVED] command to change default application to open file

[afora]

I know how to change it via GUI - the interface is pretty familiar to Windows.

However, I searched and struggled to find to do this programmatically as a script command. Can anyone suggest a way? I'm trying to associate Mirage with all image filetypes.

Many thanks!

I bet one of these commands might do it!

Code: Select all

gvfs-mime
mimeopen
mimetype
update-mime
update-mime-database  (edit: pretty sure not this one)
xdg-mime
xfce4-mime-settings (xfce4 only?)
xdg-mime

You might also look at adding/modifying some text to/in:

Code: Select all

~/.config/mimeapps.list

...like cat a file of new defaults onto the end...but I'll bet right now that that's too easy. (The file is divided up into segments)

I'm new to Linux, and I'm not quite sure how to use any of those...

Can you suggest a complete command which will take care of this?

Open the file ~/.config/mimeapps.list with the text editor.

Search for image - you'll find bmp, gif, jpeg, png and tiff e.g., image/gif=xviewer.desktop

Change xviewer to mirage

That's fantastic, thank you for your help.

Just curious - as this is only for images - is it possible to change associated application with other file types? Say, mp3s? Or text files? Or an arbitrary file type?

You can try the lines that start with audio and video or add one for mp3 since there isn't one there.

Not sure about the others

You know there is a preferred applications dialog

Just installed easytag. Now .opus files open in EasyTag not VLC (as I usually have it).
mimeapps.list is unchanged and still points to VLC.
Found that the easy way to correct this is to right-click the file in Nemo, select: Open With - Other Application, select the application (VLC in this case), then "Set as default".
Now works correcty. So mimeapps.list can't be the only place where this info is stored.
[Double Solved]!!

I believe that manual file association as you are describing would be automatically reflected in `mimeapps.list`. You may either need to restart your system or run a update command on this first to see it.
