I have a script which runs in the background (without terminal windows or TTY) and occasionally does something.

I now want it to do another thing when it does something and it is to open a Gnome Terminal window and execute 2 commands. Actually, I only need to execute 1 command but I want to make the terminal window stay open so I can see the output of the command. The command prints both on stdout and stderr and its output changes over time, so just writing it to a file and sending some kind of notification wouldn't do the job very well.

I can get Gnome Terminal to open a window and execute 1 command:

gnome-terminal -e "sleep 10"

I chose sleep as the long-running command for simplicity. However, when adding another command, no terminal window opens:

gnome-terminal -e "echo test; sleep 10"

What's the solution to this?

gnome-terminal treats everything in quotes as one command, so in order to run many of them consecutively you need to start interpreter (usually a shell), and do stuff inside it, for instance:

gnome-terminal -e 'sh -c "echo test; sleep 10"'

BTW, you may want the window to stay open even after commands finish their job, in such case just start new shell, or replace a current with the new one:

gnome-terminal -e 'sh -c "echo test; sleep 10; exec bash"'

    # Option “-e” is deprecated and might be removed in a later version of gnome-terminal.# # Use “-- ” to terminate the options and put the command line to execute after it.# That error happens now. But if you replace -e with --, the new terminal that comes up gives an error. How to correctly use --? – eric.frederich Mar 12 at 13:09

    @eric.frederich based on this answer to a question at stackoverflow, I believe the syntax should be gnome-terminal -- /bin/sh -c 'echo test; sleep 10' – wxyz Mar 26 at 6:19
