.SH "名称"
newusers \- 批量更新和创建新用户
.SH "大纲"
.HP \w'\fBnewusers\fR\ 'u
\fBnewusers\fR [\fI选项\fR] [\fI文件\fR]
.SH "描述"
.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
这是用户的用户名。
.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
.PP
\fIpw_passwd\fR
.RS 4
此字段将被加密然后用于加密后密码的新值。
.RE
.PP
\fIpw_uid\fR
.RS 4
此字段用于定义用户的 UID。
.sp
If the field is empty, a new (unused) UID will be defined automatically by
\fBnewusers\fR\&.
.sp
如果此字段包含一个数字,此数字会用于 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
如果一个现有用户更改了 UID,此用户的文件所有权需要手动修复。
.RE
.PP
\fIpw_gid\fR
.RS 4
此字段用于定义用户的主组 ID。
.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
如果此字段是一个数字,此数字会被用作此用户的主组 ID。如果没有对应此 GID 的现有组,将会使用此 GID 创建一个新组,名称和用户名相同。
.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
此字段复制到用户的 GECOS 字段。
.RE
.PP
\fIpw_dir\fR
.RS 4
此字段用于定义用户的主目录。
.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\&.
.RE
.PP
\fIpw_shell\fR
.RS 4
此字段定义了用户的 shell。对此字段不进行任何检查。
.RE
.PP
\fBnewusers\fR
first tries to create or change all the specified users, and then write these changes to the user or group databases\&. If an error occurs (except in the final writes to the databases), no changes are committed to the databases\&.
.PP
此命令一般用于在大型的应用环境中,对大量账户进行一次性更新。
