How to use commands with options in shortcuts / at startup

Running a shell command that has some options (command -opt) at startup or with a keyboard shortcut may not work, so the only solution is to create a bash script with the desired command inside and launch the script instead.
Here is what you have to do (assuming the script will be named myscript, your command is mycomm and has option -opt):

• in a Terminal (CTRL+ALT+T) type gedit myscript (or another editor instead of gedit)
• copy and paste the following code inside:
  #! /bin/bash
  mycomm -opt
• save and close
• in the Terminal type chmod +x myscript to make it executable
• move the file in /usr/bin to make it runnable: sudo cp -a myscript /usr/bin
• add /usr/bin/myscript as command to the startup processes or to your customized keyboard shortcuts.
