.TH CHSH 1
|
|
.SH NAME
|
|
chsh \- change login shell
|
|
.SH SYNOPSIS
|
|
.TP 5
|
|
\fBchsh\fR
|
|
[\fB-s \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 their 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
|
|
their 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 their login
|
|
shell back to its original value.
|
|
.PP
|
|
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 field, or leave the line blank to use
|
|
the current value.
|
|
The current value is displayed between a pair of \fB[ ]\fR marks.
