Open terminal window from script

Question

I want to run terminal or focus it by pressing F1 button. What I've tried to implement it:

1. Add custom shortcut to gnome keyboard settings with such command.

   wmctrl -s 4 && pgrep terminator || nohup terminator > /dev/null &`
   

   • wmctrl -s 4 switches screen,
   • then pgrep terminator checks if terminal already running,
   • nohup terminator > /dev/null & runs terminal if it is not.
     
     

   The screen switches right, but terminal not opens.

2. Place the command (as above) to executable *.sh file and specify absolute path to it in shortcut settings.
   All the same.

3. Run above command in another terminal.
   Works as expected. (screen switches, terminator opens)

4. Run script with above command:

   #!/bin/zsh                                                                      
   
   wmctrl -s 4 && pgrep terminator || nohup terminator > /dev/null &
   

   
   Not works again. Screen switches but terminator window not appears. Also there is pid number in the terminal after running the script.

It seems like the terminator closes after lunching for some reason.

What I should do to create shortcut with such actions?

Answer 1

I solved the problem by adding -x flag to pgrep. When I run my script named terminator.sh, pgrep always returns true and the last part of the command never executes. This is correct command:

wmctrl -s 4 && pgrep -x terminator || nohup terminator > /dev/null &
