NAME

chsh - change login shell 

SYNOPSIS

chsh [options] [LOGIN]
 

DESCRIPTION

Thechshcommand 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 superuser may change the login shell for any account. 

OPTIONS

The options which apply to thechshcommand are:

-h, --help

Display help message and exit.

-R, --root CHROOT_DIR

Apply changes in theCHROOT_DIRdirectory and use the configuration files from theCHROOT_DIRdirectory.

-s, --shell SHELL

The name of the user's new login shell. Setting this field to blank causes the system to select the default login shell.

If the-soption is not selected,chshoperates 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[ ]marks. 

NOTE

The only restriction placed on the login shell is that the command name must be listed in/etc/shells, unless the invoker is the superuser, and then any value may be added. An account with a restricted login shell may not change her login shell. For this reason, placing/bin/rshin/etc/shellsis discouraged since accidentally changing to a restricted shell would prevent the user from ever changing her login shell back to its original value. 

CONFIGURATION

The following configuration variables in/etc/login.defschange the behavior of this tool:

CHSH_AUTH (boolean)

Ifyes, thechshprogram will require authentication before making any changes, unless run by the superuser.

LOGIN_STRING (string)

The string used for prompting a password. The default is to use "Password: ", or a translation of that string. If you set this variable, the prompt will not be translated.

If the string contains%s, this will be replaced by the user's name.

 

FILES

/etc/passwd

User account information.

/etc/shells

List of valid login shells.

/etc/login.defs

Shadow password suite configuration.
