Bash Command Question

[mjheagle8]

i want to use feh to display the current amarok album art, which is given when i run the command
dcop amarok player coverImage
how do i tell feh to open that?
here's what i tried, but it didnt work:


mike@mike-laptop:~$ feh -g 40x40 "dcop amarok player coverImage"
feh WARNING: dcop amarok player coverImage does not exist - skipping
feh - No loadable images specified.
Use feh --help for detailed usage information

thanks in advance for any and all help!

I'm not sure what dcop does, but does

feh -g 40x40 < dcop amarok player coverImage
do anything?

Try using backticks. It substitutes the output of one command as a parameter to another.


feh -g 40x40 `dcop amarok player coverImage`

okay, that works. how would i be able to execute that command every 15-30 seconds or so? i'm trying watch and that's not working.

Hmm... this seems to work:



while true; do
feh -g 40x40 `dcop amarok player coverImage` &
pid=$!
sleep 20 # Or however many seconds you want it to run
kill $pid
done
