Severity: minor
File: /usr/share/man/man1/chsh.1.gz

We read

       -s, --shell SHELL
           The name of the user's new login shell. Setting this field to blank
           causes the system to select the default login shell.

However, trying it gives

# chsh -s '' nobody
chsh: Warning:  does not exist
