changing default file associations in gnome 3

[namphcar22]

How do I change the default file associations in F15/gnome 3? My system is currently set to open .tex files with emacs. But I prefer TeXworks, and while TeXworks shows up in the "Open With" menu, it would be convenient if double-clicking on a tex file opened it in TeXworks. In gnome2, the "Open with-->Other application" option let me select the default program associated with a particular type of file, but this functionality seems to be gone in Gnome 3. Do I have to edit some config file?

I have the same question, I use Mathematica software but I can't asign *.nb files with the program, it even doesn't appear on the Applications part of the shell.

Right-click->Properties->Open With->Set as default (lower right). I don't know how to do it if the application you want to use doesn't show up.

I would attach a screenshot but it is 13px too tall

Thanks. I'm marking this as solved.

Hello, I have a little bit bigger problem. I want to associate .mkv with xine. However xine-ui is not listed in applications list for associations (it's listed in menus etc.).
Does anyone have an idea dow to do that?

I also want to open a file with a program that is locally installed and I open it via command line. I don't have the option to put the path of the program to open the file like in gnome 2 ("use custom command"). Is there a workaround to this problem??

Cheers,
Germán.

- First look for the program (.desktop) in /usr/share/applications.
- Edit the program file so that the Exec line looks like:
Exec=yourprogram %U
- Now the program should show up in application list

THIS. Worked on Fedora 20. Thanks.

EDIT: ****, didn't mean to bump up such an old thread. Sorry.

Addendum if the program is not going to open URLs then %f and %F may be more appropriate.

Exec=Command Line
The command line to start the application. If the application can open files the %f placeholder should be specified. When a file is dropped on the application launcher the %f is replaced with the file path of the dropped file. If multiple files can be specified on the command line the %F placeholder should be used instead of %f. If the application is able to open URLs in addition to local files then %u or %U can be used instead of %f or %F.

Hi All,

Fedora 25 Spin: Cinnamon

After some research I ended up here (this forum)

https://unix.stackexchange.com/quest...ations-gnome-3 (last one)

I removed Firefox completely and I'm using Iron Browser.
After moving the iron-browser.desktop file (created with menu libre) to /usr/share/applications, it was
not showing in Preferred Applications

It seems that using DNF for installation,you will find the application in the application list of Preferred Applications.
For Iron Browser, I had only a tar file for Fedora, After un-tar, I moved the directory to /opt.

In the directory /usr/share/applications you have a file called "mimeapps.list". Using Nano I replaced firefox.desktop with iron-browser.desktop and restart my laptop

And it is showing in the application list and selected for Web : Iron Browser
