.SH "NOME"
chsh \- cambia la shell di login
.SH "SINOSSI"
.HP \w'\fBchsh\fR\ 'u
\fBchsh\fR [\fIopzioni\fR] [\fILOGIN\fR]
.SH "DESCRIZIONE"
.PP
The
\fBchsh\fR
command changes the user login shell\&. This determines the name of the user\*(Aqs 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\&.
.SH "OPZIONI"
.PP
The options which apply to the
\fBchsh\fR
command are:
.PP
\fB\-h\fR, \fB\-\-help\fR
.RS 4
Mostra un messaggio di aiuto ed esce\&.
.RE
.PP
\fB\-R\fR, \fB\-\-root\fR\ \&\fICHROOT_DIR\fR
.RS 4
Apply changes in the
\fICHROOT_DIR\fR
directory and use the configuration files from the
\fICHROOT_DIR\fR
directory\&.
.RE
.PP
\fB\-s\fR, \fB\-\-shell\fR\ \&\fISHELL\fR
.RS 4
Il nome della nuova shell di login dell\*(Aqutente\&. Lasciando questo campo vuoto si fa in modo che il sistema selezioni la shell di login predefinita\&.
.RE
.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 shell, or leave the line blank to use the current one\&. The current shell is displayed between a pair of
\fI[ ]\fR
marks\&.
.SH "NOTA"
.PP
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/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\&.
.SH "CONFIGURAZIONE"
.PP
The following configuration variables in
/etc/login\&.defs
change the behavior of this tool:
.PP
\fBCHSH_AUTH\fR (boolean)
.RS 4
If
\fIyes\fR, the
\fBchsh\fR
program will require authentication before making any changes, unless run by the superuser\&.
.RE
.PP
\fBLOGIN_STRING\fR (string)
.RS 4
Il testo da utilizzare per richiedere la password\&. Il valore predefinito \(`e \(FoPassword: \(Fc o una sua traduzione\&. Se si imposta questa variabile allora il testo non verr\(`a tradotto\&.
.sp
If the string contains
\fI%s\fR, this will be replaced by the user\*(Aqs name\&.
.RE
.SH "FILE"
.PP
/etc/passwd
.RS 4
Informazioni sugli account utente\&.
.RE
.PP
/etc/shells
.RS 4
Elenco delle shell di login ammesse\&.
.RE
.PP
/etc/login\&.defs
.RS 4
Configurazione del pacchetto password shadow
.RE
.SH "VEDERE ANCHE"
.PP
\fBchfn\fR(1),
\fBlogin.defs\fR(5),
\fBpasswd\fR(5)\&.
