Sorry. I've lost the thread here, what is the "it" you refer to?

If you run the command

  grep nut /etc/password

you will probably receive a reply similar to


The /bin/false implies that user nut uses the default shell which can be seen on 
a Debian box with the command

  ls -alF /bin/sh
  lrwxrwxrwx 1 root root 4 Jan 24  2017 /bin/sh -> dash*

This says that Dash is the default for the command line and for scripts.  As 
Manuel has said this can be changed with the first line of a script, e.g.


says that this script uses Bash.
