chsh - change default login shell
chsh login-name [shell]
chsh -r files login-name [shell]
chsh -r nisplus login-name [shell]
chsh -r nis login-name [shell]
chsh -r dce login-name [shell]
The chsh command changes the login-shell for a user's login name in
the repository (see passwd(1)).
The DCE repository (-r dce) is only available if Integrated Login has
been configured, see auth.adm(1M). If Integrated Login has been
configured, other considerations apply. A user with appropriate DCE
privileges is capable of modifying a user's shell; this is not
dependent upon superuser privileges.
If the repository is not specified; i.e., chsh [login-name], the login
shell is changed in passwd file only.
Run finger after running chsh to make sure the information was
login-name A login name of a user.
shell The absolute path name of a shell. If the file
/etc/shells exists, the new login shell must be
listed in that file. Otherwise, you can specify one
of the standard shells listed in the getusershell(3C)
manual entry. If shell is omitted, it defaults to
the POSIX shell, /usr/bin/sh.
The following option is recognized:
-r Specify the repository to which the operation is
to be applied. Supported repositories include
files, nis, nisplus, and dce.
You must have the syslog sensitivity label to execute chsh. You must
have the owner kernel authorization to change another user's login

To change the login shell for user voltaire to the default:
To change the login shell for user descartes to the C shell:
chsh descartes /usr/bin/csh
To change the login shell for user aristotle to the Korn shell in the
chsh -r dce aristotle /usr/bin/ksh
As many users may try to write the /etc/passwd file simultaneously, a
passwd locking mechanism was deviced. If this locking fails after
subsequent retrying, chsh terminates.
chsh was developed by HP and the University of California, Berkeley.
The chsh command is a hard link to passwd command. When chsh is
executed actually the passwd command gets executed with appropriate
arguments to change the user login shell in the repository specified
in command line. If no repository is specified the login shell is
changed in /etc/passwd file.
