.SH "SYNOPSIS"
.HP \w'\fBnewusers\fR\ 'u
\fBnewusers\fR [\fIoptions\fR] [\fIfile\fR]
.SH "DESCRIPTION"
.PP
The
\fBnewusers\fR
command reads a
\fIfile\fR
(or the standard input by default) and uses this information to update a set of existing users or to create new users\&. Each line is in the same format as the standard password file (see
\fBpasswd\fR(5)) with the exceptions explained below:
.PP
pw_name:pw_passwd:pw_uid:pw_gid:pw_gecos:pw_dir:pw_shell
.PP
\fIpw_name\fR
.RS 4
C\*(Aqest le nom de l\*(Aqutilisateur\&.
.sp
It can be the name of a new user or the name of an existing user (or a user created before by
\fBnewusers\fR)\&. In case of an existing user, the user\*(Aqs information will be changed, otherwise a new user will be created\&.
.RE

.RE
.PP
\fIpw_uid\fR
.RS 4
Ce champ est utilis\('e pour d\('efinir l\*(AqUID de l\*(Aqutilisateur\&.
.sp
If the field is empty, a new (unused) UID will be defined automatically by
\fBnewusers\fR\&.
.sp
Si ce champ contient un nombre, ce nombre sera utilis\('e comme UID\&.
.sp
If this field contains the name of an existing user (or the name of a user created before by
\fBnewusers\fR), the UID of the specified user will be used\&.
.sp
Si l\*(AqUID d\*(Aqun utilisateur existant est modifi\('e, vous devrez configurer vous\-m\(^eme le propri\('etaire des fichiers de l\*(Aqutilisateur\&.
.RE
.PP
\fIpw_gid\fR
.RS 4
Ce champ est utilis\('e pour d\('efinir l\*(Aqidentifiant du groupe primaire de l\*(Aqutilisateur\&.
.sp
If this field contains the name of an existing group (or a group created before by
\fBnewusers\fR), the GID of this group will be used as the primary group ID for the user\&.
.sp
Si ce champ est un nombre, ce nombre sera utilis\('e comme identifiant de groupe primaire de cet utilisateur\&. Si aucun groupe n\*(Aqexiste avec ce GID, un nouveau groupe sera cr\('e\('e avec ce GID et le nom de l\*(Aqutilisateur\&.
.sp
If this field is empty, a new group will be created with the name of the user and a GID will be automatically defined by
\fBnewusers\fR
to be used as the primary group ID for the user and as the GID for the new group\&.
.sp
If this field contains the name of a group which does not exist (and was not created before by
\fBnewusers\fR), a new group will be created with the specified name and a GID will be automatically defined by
\fBnewusers\fR
to be used as the primary group ID for the user and GID for the new group\&.
.RE
.PP
\fIpw_gecos\fR
.RS 4
Ce champ est copi\('e dans le champ GECOS de l\*(Aqutilisateur\&.
.RE
.PP
\fIpw_dir\fR
.RS 4
Ce champ est utilis\('e pour d\('efinir le r\('epertoire personnel de l\*(Aqutilisateur\&.
.sp
If this field does not specify an existing directory, the specified directory is created, with ownership set to the user being created or updated and its primary group\&. Note that
\fInewusers does not create parent directories \fR
of the new user\*(Aqs home directory\&. The newusers command will fail to create the home directory if the parent directories do not exist, and will send a message to stderr informing the user of the failure\&. The newusers command will not halt or return a failure to the calling shell if it fails to create the home directory, it will continue to process the batch of new users specified\&.
.sp
If the home directory of an existing user is changed,
\fBnewusers\fR
does not move or copy the content of the old directory to the new location\&. This should be done manually\&.

\fIpw_shell\fR

\fBSYS_UID_MIN\fR\-\fBSYS_UID_MAX\fR
range, defined in
login\&.defs, instead of
\fBUID_MIN\fR\-\fBUID_MAX\fR
(and their

counterparts for the creation of groups)\&.
.RE
.PP
\fB\-R\fR, \fB\-\-root\fR\ \&\fICHROOT_DIR\fR

.sp
You can only use this option with crypt method:
\fISHA256\fR \fISHA512\fR
.sp
By default, the number of rounds for SHA256 or SHA512 is defined by the SHA_CRYPT_MIN_ROUNDS and SHA_CRYPT_MAX_ROUNDS variables in
/etc/login\&.defs\&.
.sp
A minimal value of 1000 and a maximal value of 999,999,999 will be enforced for SHA256 and SHA512\&. The default is 5000\&.
