I am having trouble terminating applications started from the terminal - for example, I used:
cd /usr/bin and ls to determine that the gimp app is here.

I then started gimp by typing "gimp" - started successfully.

BUT, I cant stop / exit the program. There is no "$" sign from which to start (indicating that the process is running, I suppose).

I have tried: (gimp:23558): GEGL-gegl-operation.c-WARNING \*\*: Cannot change name of operation class 0x29DFB70 from "gimp:point-layer-mode" to "gimp:anti-erase-mode"

kill
pwd
kill
exit
q
quit
Q
QUIT
TERM
SIGTERM

None of these work - neither would I expect them to because there is no "$" sign to begin from.
