Dear fellow Fedoreans,
How can I make sure that only one instance of gkrellm runs. When I start one of my machines run several instances of gkrellm. I chose in the configuration run only one, but that does not work :(

As you can see there are several gkrellm's running :(
Cameron shared a script with me:
#!/bin/bash
#
pidfile=$HOME/.grkrellm.pid
if [ -s "$pidfile" ] && pid=$(<"$pidfile") && kill -0 "$pid" 2>/dev/null
then
echo GKrellM already running, pid=$pid, not starting a new one.
else
gkrellm & # start gkrellm
echo $! >"$pidfile" # save the pid
fi
And it finds that gkrellm is already running so it quits. The script works, but I have to find a way to eliminate the extra gkrellm's.
How can I prevent the other gkrellm's and run only one?
TIA,
Antonio
