rof

rof is a launcher script to avoid launching multiple instances of the same window. The name stands for [r]un [o]r set [f]ocus).

While playing with my collection of Tint2 executors one of things I hated most was that commands assigned to mouse events would execute again and again after each click, even if previous instances were already running. The behavior I expected was: launch the command if not yet running, else just bring focus to the command window. Having no better idea on how to achieve this, I wrote this short script. It searches the process ID of the name given, then tries to find a window by the process ID. If found, it'll be given focus, instead of running the command again.

Dependencies:

xorg-xprop, wmctrl (valid for Arch Linux; package names may vary in other distributions)

Usage:

rof [-P process_name] command

Use rof command to simply run if the command and the process name are the same.

Provide the optional process name, for instance if the command is a script which runs another command:

rof -P zenity zenity-set-volume.sh

launches the script which opens a zenity box, with arguments: zenity --scale --value ${lvl} --title "Volume" --text "Set master volume level"

Sample:

The script may be useful in a Tint2 executor left/right click commands:
