I was emptying the trash on my machine (Debian 8 Jessie with the MATE desktop) and then did some other operation. Long story short, the whole file explorer is frozen. I can't seem to find anything in htop because I don't know what the file explorer's process is called. How can I restart the file explorer only?

The process is called caja.

I didn't find out until after I sudo apt-get install gnome-system-monitor and saw the little file cabinet icon next to a process called caja. Killing that worked. Now I know the process is called caja and can of course also see it in htop now after a restart.


If the explorer can get itself out by itself:

caja --quit
nautilus --quit

the desktop will restart automatically.
