On a fairly regular basis I need to fire off a quick, no-output command ... like: killall ssh kill -HUP `pidof Sonos` knock server.com 20 40 60 umount /dev/md0 and so on ... these are very simple, one line unix commands that have no output, and I don't really need to fire up terminal, run it, close terminal, etc. I'd really love to just hit F10 or something and type into a dialog that comes up (or pops up on the bottom of the screen, etc.) Does anyone know of any applications or addons that give me that functionality ? In a way it is like the start menu -> run function in windows - just a place to type in a quick one-off command... Thanks for any suggestions.
