[GRASS-user] exit from grass after setting GRASS env variable

GRASS GRASS user
1

Hi,

i have a very simple question but i’m not able find the simple answer.

I’m following the procedure for Setting the GRASS environmental variables, in the bash environment.

Everything works grate and I’m able to access to all grass commands.

My question is how I can exit from grass and return to the bash-with-nograss.

I tested

exit
exit 1
exit 0

but all of them close the full terminal.

I would like to be able to close GRASS but have all the bash terminal available.

Any idea?

Thanks

Giuseppe

You cannot "exit" GRASS as it is not an application by itself. If you do not want to have access to the GRASS modules anymore, just unset your environment variables.

If you want to change your prompt, set PS1 to something else.

You cannot "exit" GRASS as it is not an application by itself. If you do
not want to have access to the GRASS modules anymore, just unset your
environment variables.

Alternatively, you could just spawn a separate shell (with "bash")
before setting any of the GRASS environment variables then terminate
it (with "exit") when you're finished.

A child process (normally) inherits its environment from its parent at
start-up, but any changes to the child's environment won't affect the
parent's.
