I used the script above, yes the file ends in .sh and I saved the file in Kwrite (>save as> swmb.sh). I have no idea what i did wrong but it always opens up Kwrite instead of toggling. I set up the toggle by following your instructions (Input Actions>Command/URL) and set it to /home/user/swmb.sh where the file is.
