| May 2, 2016 at 6:50 | comment | added | Vombat | Open your .bashrc and comment out every line there. Keep only a single line containing a command like echo "test" or similar. Save and close. Then run bash and immediately echo $_. This last echo should print test in the output. | |
| May 2, 2016 at 0:00 | comment | added | Tim | Thanks. (1) can you explain the third case with examples? (2) When I open a new gnome terminal tab, the output of echo $_ is EDITOR, and why is it?
