NAME
       shells - pathnames of valid login shells

DESCRIPTION
       /etc/shells  is  a  text  file which contains the full pathnames of valid login shells.  This
       file is consulted by chsh(1) and available to be queried by other programs.

       Be aware that there are programs which consult this file to find out if a user  is  a  normal
       user;  for  example,  FTP  daemons traditionally disallow access to users with shells not in‐
       cluded in this file.

FILES

EXAMPLES
       /etc/shells may contain the following paths:

           /bin/sh
