Mac OS X 10.5 (Leopard) introduced a new, 3D, reflective Dock. For those of us who prefer the Dock to be a little less distracting, this command is the answer. The Dock will be rendered in the same style as when pinned to the left- or right-hand side of the screen. Replace YES with NO to restore the 3D Dock.

This command is suitable to use as application launching command for a desktop shortcut. It checks if the application is already running by pgrepping its process ID, and offer user to kill the old process before starting a new one. It is useful for a few x11 application that, if re-run, is more likely a mistake. In my example, x2vnc is an x11 app that does not quit when its connection is broken, and would not work well when a second process establish a second connection after the first broken one. The LC_ALL=C for xmesseng is necessary for OpenSUSE systems to avoid a bug. If you don't find needing it, remove the "env LC_ALL=C" part

The other 2 commands that are listed will also kill the egrep process and any libexec processes because the .exe isn't escaped so it is really using . meaning anything containing exe. The command i posted escapes the (dot) in .exe and then filters the actual egrep process so that it doesn't get killed before the other processes being killed. Also added the -9 switch for kill to send sigterm to the processes, in case people are wondering why processes aren't getting killed after running just kill . This should work better for people :)

I use this loop for a variety of things. If a process won't die, I try to ask it nicely to let it die gracefully, and then i use killall and kill -9 to end its life. This will run the program killall and then start it again when it completes, indefinately.
