This doesn't work properly. Look at this snippet: cat test.sh readlink -f /proc/$$/exe echo $SHELL zsh test.sh /bin/zsh /bin/bash When running a script the $SHELL variable will not change, whereas the PID will, so it's more reliable.

echo $0 is the best

echo $0 returns the name of the current shell or program. Pop it into a script and run it and it will return the name of the script not the name of the shell. echo $SHELL is more reliable.

"echo $0" in guake returns "-" and in gnome-terminal returns "-bash". If you run "exec -a csh bash", then in $0 you have "csh"
