SHELLS(5)                 OpenBSD Programmer's Manual                SHELLS(5)

NAME
     shells - shell database

DESCRIPTION
     The shells file contains a list of valid shells available on the system.
     A shell is a command line interpreter that reads user input and executes
     commands.  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 char-
     acters up to the end of the line are not interpreted by the routines
     which search the file.  Blank lines are also ignored.

     The chpass(1) program will not let regular users change their default
     shell to one not listed in the shells file.  The ftpd(8) daemon denies
     access to users who are not using one of the listed shells.

FILES
     /etc/shells

SEE ALSO
     chpass(1), login(1), getusershell(3), nologin(8)

HISTORY
     The shells file format appeared in 4.3BSD-Tahoe.
