execute script to open terminal to run root commands

I’m looking to run a shell script by double-clicking it from desktop gui for my ubuntu server (v20).

I would like the shell script to run these commands in a terminal window when I double click it:

• sudo -i (prompt for password) then under root =
• xhost +
• unset XAUTHORITY
• export DISPLAY=:0
• ssa -local

it must run in that order as I have to do this so I can run hp ssa under root

I’ve tried all sorts of ways to get it to run, but I cannot. Any help is appreciated!

Thanks

For Gnome Terminal, which comes with a default Ubuntu install, that can be achieved with a custom profile. In the Preferences dialog, create a new profile, e.g. rootshell. On the "Command" tab of the new profile, specify your shell script as "Custom command". That can be exactly as you hinted to, however preferably include a shebang.

#!/bin/bash
sudo -i
xhost +
unset XAUTHORITY
export DISPLAY=:0
ssa -local

In your .desktop launcher, launch this custom terminal as:

Exec=gnome-terminal --window-with-profile=rootshell

Double-clicking the launcher will start Gnome Terminal with the custom profile. On startup, Gnome Terminal will run the script: your user password is asked to elevate priviledges to root. Subsequent commands are executed, and finally, you are dropped at a root prompt, with an environment customized through your script.

If you use a different terminal emulator, a similar approach will apply in most cases. However, details on how to configure will vary.
