open terminal run command python

Question

I am trying to open a terminal and run a command in it. I am using

os.system("gnome-terminal -e 'bash -c \"exec bash; MY_COMMAND; exec bash\" '")

This opens up a new terminal, but the command is not executed.

Answer 1

The exec command replaces the currently running process with a new one, so if you have an exec in a list of commands to run, as soon as exec is run, nothing else will run. So you're replacing 'bash -c \"exec bash; MY_COMMAND; exec bash\" ' with bash, and then nothing after the exec bash is running. Try this instead:

os.system("gnome-terminal -e 'bash -c \"MY_COMMAND\" '")

or if you need a terminal to stay open, try this:

os.system("gnome-terminal -e 'bash -c \"MY_COMMAND; sleep 1000000\" '")

of if you want the terminal to stay open and be in a bash shell, try this:

os.system("gnome-terminal -e 'bash -c \"MY_COMMAND; bash\" '")
