the name of the user's initial login command. A normal user may only

If the <option>-s</option> option is not selected,
|
|
<command>chsh</command> 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 <emphasis>[ ]</emphasis> marks.

|
|
The only restriction placed on the login shell is that the command
|
|
name must be listed in <filename>/etc/shells</filename>, 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 <filename>/bin/rsh</filename> in
|
|
<filename>/etc/shells</filename> is discouraged since accidentally
|
|
changing to a restricted shell would prevent the user from ever
|
|
changing her login shell back to its original value.
