How to check if metacity is running?

[Amnon82]

Lately sometimes metacity dosn't get startet. I've to open a terminal to start it manually. Is there a way to create a script which checks if metacity got started and if not the script will do it for me?

provided X is already started, but no other window
manager is running, try this:

if ! `ps -a | grep -s metacity`
then exec metacity
fi
