shells(4)

NAME

     shells - shell database

SYNOPSIS

     /etc/shells

DESCRIPTION

     The shells file contains a list of the shells on the system.
     Applications  use  this file to determine whether a shell is
     valid. See getusershell(3C). For each shell  a  single  line
     should  be present, consisting of the shell's path, relative
     to root.

     A hash mark (#) indicates the beginning of a comment; subse-
     quent  characters  up  to the end of the line are not inter-
     preted by the routines which search the  file.  Blank  lines
     are also ignored.

     The  following  default  shells  are  used   by   utilities:
     /bin/bash,   /bin/csh,   /bin/jsh,   /bin/ksh,   /bin/pfcsh,
     /bin/pfksh,   /bin/pfsh,   /bin/sh,   /bin/tcsh,   /bin/zsh,
     /sbin/jsh,     /sbin/sh,     /usr/bin/bash,    /usr/bin/csh,
     /usr/bin/jsh, /usr/bin/ksh, /usr/bin/pfcsh,  /usr/bin/pfksh,
     /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh.
     Note that /etc/shells overrides the default list.

     Invalid shells in /etc/shells may cause unexpected  behavior
     (such as being unable to log in by way of ftp(1)).
