A desktop file is standardized configuration file for Linux desktops
that describe how to represent a program in the menus (complete with
multiple language support), and how to launch it. So you can't just
launch it directly because it doesn't mean anything to the command
line. It should however be showing up in your menus now and so you can
put it in your favorites and easily launch it that way.
That being cause, you can kinda turn it into an executable by adding
something like the following to the very top of the desktop file:
#!/usr/bin/kioclient5 exec
That will tell the system to execute the desktop file with kioclient...
of course you need to be running KDE for that to work correctly. I'm
not sure what the GNOME equivalent of that command is.
Personally I would just pretty alt+F2 or alt+space may work as well and
just start to type "Sandboxed Web Browser" and you may only have to
type Sand or so before you can press enter and have it launch.
Alternatives to starting it from the command line:
Create a file called sandfox in /usr/local/bin/ and put the following
into it.
#!/bin/bash
/usr/bin/firejail --apparmor firefox $@
Then set it to be executable and then you can execute sandfox from anywhere.
You could also set and alias with:
alias sandfox="/usr/bin/firejail --apparmor firefox"
That will allow you to type sandfox and internally it will replace that
with "/usr/bin/firejail --apparmor firefox". That should also work in
most places equally well, but only for your username.
That's a one shot way of making that available. If you want it to be
permanent you'll need to add that line to your .bashrc file with:
echo alias sandfox='"/usr/bin/firejail --apparmor firefox"' >>~/.bashrc
I can't remember what your original goals were, so I hope the above
isn't completely shooting the dark.
