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; subsequent
characters up to the end of the line are not interpreted 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/ksh93, /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/ksh93, /usr/bin/pfcsh,
/usr/bin/pfksh, /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh,
/usr/bin/zsh, and /usr/sfw/bin/zsh. /etc/shells overrides the default
list.


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