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. E.g.: ftp daemons  traditionally  disallow
       access to users with shells not included in this file.

EXAMPLES
       /etc/shells may contain the following paths:

	      /bin/sh
	      /bin/csh

FILES
       /etc/shells
