.SH NAME
chsh \- change login shell
.SH SYNOPSIS
.TP 5
\fBchsh\fR [\fB\-s\fR \fIlogin_shell\fR] [\fIuser\fR]
.SH DESCRIPTION
\fBchsh\fR changes the user login shell. This determines the name of the
user's initial login command. A normal user may only change the login shell
for her own account, the super user may change the login shell for any
account.
.PP
The only restrictions placed on the login shell is that the command name
must be listed in \fI/etc/shells\fR, unless the invoker is the super\-user,
and then any value may be added. An account with a restricted login shell
may not change her login shell. For this reason, placing \fB/bin/rsh\fR in
\fI/etc/shells\fR is discouraged since accidentally changing to a restricted
shell would prevent the user from every changing her login shell back to its
original value.
.PP
.SH OPTIONS
If the \fB\-s\fR option is not selected, \fBchsh\fR operates in an
interactive fashion, prompting the user with the current login shell. Enter
the new value to change the shell, or leave the line blank to use the
current one. The current shell is displayed between a pair of \fB[ ]\fR
marks.
.SH FILES
\fI/etc/passwd\fR	\- user account information
.br
\fI/etc/shells\fR	\- list of valid login shells
