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 During this first pass, users are created with a locked password (and passwords are not changed for the users which are not created)\&. A second pass is used to update the passwords using PAM\&. Failures to update a password are reported, but will not stop the other password updates\&. .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。 .SH "选项" .PP The options which apply to the \fBnewusers\fR command are: .PP \fB\-\-badname\fR\ \& .RS 4 Allow names that do not conform to standards\&. .RE .PP \fB\-h\fR, \fB\-\-help\fR .RS 4 显示帮助信息并退出。 .RE .PP \fB\-r\fR, \fB\-\-system\fR .RS 4 创建一个系统账户。 .sp System users will be created with no aging information in /etc/shadow, and their numeric identifiers are chosen in the \fBSYS_UID_MIN\fR\-\fBSYS_UID_MAX\fR range, defined in login\&.defs, instead of \fBUID_MIN\fR\-\fBUID_MAX\fR (and their \fBGID\fR counterparts for the creation of groups)\&. .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 .SH "CAVEATS" .PP 输入文件必须受到保护，因为它包含未加密的密码。 .SH "配置文件" .PP The following configuration variables in /etc/login\&.defs change the behavior of this tool: .SH "文件" .PP /etc/passwd .RS 4 用户账户信息。 .RE .PP /etc/shadow .RS 4 安全用户账户信息。 .RE .PP /etc/group .RS 4 组账户信息。 .RE .PP /etc/gshadow .RS 4 安全组账户信息。 .RE .PP /etc/login\&.defs .RS 4 Shadow 密码套件配置。 .RE .PP /etc/pam\&.d/newusers .RS 4 PAM configuration for \fBnewusers\fR\&. .RE .PP /etc/subgid .RS 4 Per user subordinate group IDs\&. .RE .PP /etc/subuid .RS 4 Per user subordinate user IDs\&. .RE .SH "参见" .PP \fBlogin.defs\fR(5), \fBpasswd\fR(1), \fBsubgid\fR(5), \fBsubuid\fR(5), \fBuseradd\fR(8)\&.
