is_running detection implementation

[thetrompf]

Wouldn't it better to leverage the /proc filesystem to figure out if the process is running instead of "parsing" ps output with awk and grep?

is_running() {
    [ -d "/proc/$(get_pid)" ] 
}

Good idea. Can you submit a PR?

Yes I can, I'll to it tonight
