show output from script that would be seen in terminal

Question

I have working scripts for windscribe vpn. At this time there is no GUI. They run from the desktop no problem. How do I see the output that I would see in the terminal.

I can get the notification window up but how do I get the output in there?

I don't think it matters what the commands are there must be basic command to make this happen.

Is there a better way than using notification window?

Answer 1

You could redirect the output to some files, e.g. like this:

./yourscript.sh 1> log.txt 2> errlog.txt

then you could open another terminal window and there you could do something like

tail -f log.txt

and then you should see the output there. The -f option to the tail command means that output is appended as the file grows.

Answer 2

Despite the Q saying you don't have a GUI, apparently you have a Desktop and gnome-terminal, so I'm assuming you also have zenity installed too (it's in Ubuntu by default), so you could have zenity display the output from a command, or from an entire script, like this:

script_output=$(script.sh)
zenity --info --title="Output of script" --text="$script_output"

It will save the standard output (excluding stderr, you could redirect it to stdout too if you wanted) to a variable, then have zenity open a window showing the output in a box similar to this image (but with a different title & contents) that will stay up until you press ok.

You can open a new terminal window and run the command in it, e.g. with xterm :

xterm -hold -e 'whoami'

The -hold option lets the window stay open, remove it if you want it to auto-close immediately when the process exits. You can also use sleep to let it stay open for a defined period of time after the exit, e.g. xterm -e 'whoami;sleep 2'. The part after-e` is the command or command list to be executed in the new terminal window. This must be the last option on the command line. Note that it doesn’t run a shell if you don’t tell it to do so.

Most other terminal emulators have the same or a similar option, e.g.

gnome-terminal -e 'whoami'

If there’s no equivalent to xterm’s -hold flag you can start a shell to keep the window open:

xterm -e 'whoami;bash'
