CHSH(1)

NOME
chsh - cambia la shell di login

SINOSSI

chsh [options] [LOGIN]

DESCRIZIONE

The chsh command 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.

OPZIONI

The options which apply to the chsh command are:

-h, --help
    Mostra un messaggio di aiuto ed esce.

-R, --root CHROOT_DIR
    Apply changes in the CHROOT_DIR directory and use the configuration files from the CHROOT_DIR directory. Only absolute paths are supported. No SELINUX support.

-s, --shell SHELL
    Il nome della nuova shell di login dell'utente. Lasciando questo campo vuoto si fa in modo che il sistema selezioni la shell di login predefinita.

If the -s option is not selected, chsh 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 [ ] marks.

NOTA

The only restriction placed on the login shell is that the command name must be listed in /etc/shells.

If the invoker is the superuser any value may be added regardless what is defined in the configuration files. An account with a restricted login shell may not change her login shell. For this reason, placing /bin/rsh in /etc/shells is discouraged since accidentally changing to a restricted shell would prevent the user from ever changing her login shell back to its original value.

CONFIGURAZIONE

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

CHSH_AUTH (boolean)
    If yes, the chsh program 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.

FILE

/etc/passwd
    Informazioni sugli account utente.

/etc/shells
    Elenco delle shell di login ammesse.

/etc/login.defs
