Terminator: single window, focus on launch

I am configuring Terminator for my desktop. I use the Ctrl + Alt + T shortcut to launch it. Since I want only a single instance running, I use run-one terminator as the launcher command.

Now if an Terminator instance is running, a new instance isn`t launched, but the existing instance does not get focused.

Any ideas as to how I could get the Terminator window to get focus?

Here is a method that works without run-one assuming wmctrl is available:

wmctrl -xa terminator.Terminator || terminator

This assumes the default window class name is being used. You can get creative if you want and use a custom class name when launching terminator. This will allow you to keep your terminator shortcut separate from a normal terminator instance:

wmctrl -xa MyCustomTerminator.Terminator || terminator -c MyCustomTerminator

This just builds on Denis' answer without the need for run-one.

Try to install wmctrl : sudo apt-get install wmctrl
now the command wmctrl -a STRING gives focus to a window containing STRING in its title
so your final command will be:

run-one terminator; wmctrl -a Terminator

Here is the hack I have settled upon using run-one and xdotool

In /home/(user)/my_scripts/single_terminator_instance.sh

#!/usr/bin/bash

# run a single instance of terminator
/usr/bin/run-one /usr/bin/terminator

# search for the terminator window and focus!!!
/usr/bin/xdotool search --onlyvisible --class terminator windowactivate

Then

1. Change Terminator shortcut command in Main Menu to point to the above script
2. In Keyboard shortcuts, Ctrl + Alt + T activates the script

While searching across the i'net, I also chanced upon this

Since I am new to bash scripts, I welcome any refinements to the hack!
