.SH "NOM"
chsh \- Changer l\*(Aqinterpr\('eteur de commandes initial
.SH "SYNOPSIS"
.HP \w'\fBchsh\fR\ 'u
\fBchsh\fR [\fIoptions\fR] [\fILOGIN\fR]
.SH "DESCRIPTION"
.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 "OPTIONS"
.PP
The options which apply to the
\fBchsh\fR
command are:
.PP
\fB\-h\fR, \fB\-\-help\fR
.RS 4
Afficher un message d\*(Aqaide et quitter\&.
.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\&. Only absolute paths are supported\&.
.RE
.PP
\fB\-s\fR, \fB\-\-shell\fR\ \&\fISHELL\fR
.RS 4
Nom du nouvel interpr\('eteur de commandes initial (\(Fo\ \&login shell\ \&\(Fc) de l\*(Aqutilisateur\&. Si ce champ est vide, le syst\(`eme s\('electionnera l\*(Aqinterpr\('eteur de commandes initial par d\('efaut\&.
.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 "NOTE"
.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 "CONFIGURATION"
.PP
The following configuration variables in
/etc/login\&.defs
change the behavior of this tool:
.SH "FICHIERS"
.PP
/etc/passwd
.RS 4
Informations sur les comptes des utilisateurs\&.
.RE
.PP
/etc/shells
.RS 4
Liste des interpr\('eteurs de commandes initiaux valables\&.
.RE
.PP
/etc/login\&.defs
.RS 4
Configuration de la suite des mots de passe cach\('es \(Fo\ \&shadow password\ \&\(Fc\&.
.RE
.SH "VOIR AUSSI"
.PP
\fBchfn\fR(1),
\fBlogin.defs\fR(5),
\fBpasswd\fR(5)\&.
