newusers - обновляет и создаёт новые учётные записи пользователей в пакетном режиме
СИНОПСИС
newusers [options] [file]
ОПИСАНИЕ
The newusers command reads a file (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 passwd(5)) with the exceptions explained below:
pw_name:pw_passwd:pw_uid:pw_gid:pw_gecos:pw_dir:pw_shell
pw_name
It can be the name of a new user or the name of an existing user (or a user created before by newusers). In case of an existing user, the user's information will be changed, otherwise a new user will be created.
pw_passwd
pw_uid
If the field is empty, a new (unused) UID will be defined automatically by newusers.
Если в этом поле указано число, то оно будет использовано в качестве UID.
If this field contains the name of an existing user (or the name of a user created before by newusers), the UID of the specified user will be used.
Если изменяется UID существующего пользователя, то у файлов, которыми владел этот пользователь, нужно вручную переопределить владельца.
pw_gid
If this field contains the name of an existing group (or a group created before by newusers), the GID of this group will be used as the primary group ID for the user.
Если в этом поле содержится число, то это число будет использовано как ID первичной группы пользователя. Если с таким GID не существует, то будет создана новая группа с этим GID и именем пользователя.
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 newusers to be used as the primary group ID for the user and as the GID for the new group.
If this field contains the name of a group which does not exist (and was not created before by newusers), a new group will be created with the specified name and a GID will be automatically defined by newusers to be used as the primary group ID for the user and GID for the new group.
pw_gecos
pw_dir
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 newusers does not create parent directories of the new user's 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.
If the home directory of an existing user is changed, newusers does not move or copy the content of the old directory to the new location. This should be done manually.
pw_shell
newusers 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.
Во время первого прохода пользователи создаются с заблокированными паролями (у несоздаваемых пользователей пароли не изменяются). Во время второго прохода выполняется обновление паролей с помощью PAM. При возникновении ошибок при обновлении об этом сообщается, но обновление паролей продолжается.
Данная команда предназначена для работы в крупных системных средах, где за один раз обновляется несколько учётных записей.
ПАРАМЕТРЫ
The options which apply to the newusers command are:
--badname
-h, --help
-r, --system
System users will be created with no aging information in /etc/shadow, and their numeric identifiers are chosen in the SYS_UID_MIN-SYS_UID_MAX range, defined in login.defs, instead of UID_MIN-UID_MAX (and their GID counterparts for the creation of groups).
-R, --root CHROOT_DIR
ПРЕДОСТЕРЕЖЕНИЯ
Файл с входными данными должен быть защищён, так как в нём содержатся не шифрованные пароли.
НАСТРОЙКА
The following configuration variables in /etc/login.defs change the behavior of this tool:
GID_MAX (number), GID_MIN (number)
The default value for GID_MIN (resp. GID_MAX) is 1000 (resp. 60000).
HOME_MODE (number)
useradd and newusers use this to set the mode of the home directory they create.
MAX_MEMBERS_PER_GROUP (number)
The default value is 0, meaning that there are no limits in the number of members in a group.
This feature (split group) permits to limit the length of lines in the group file. This is useful to make sure that lines for NIS groups are not larger than 1024 characters.
If you need to enforce such limit, you can use 25.
Note: split groups may not be supported by all tools (even in the Shadow toolsuite). You should not use this variable unless you really need it.
PASS_MAX_DAYS (number)
PASS_MIN_DAYS (number)
PASS_WARN_AGE (number)
SUB_GID_MIN (number), SUB_GID_MAX (number), SUB_GID_COUNT (number)
The default values for SUB_GID_MIN, SUB_GID_MAX, SUB_GID_COUNT are respectively 100000, 600100000 and 65536.
SUB_UID_MIN (number), SUB_UID_MAX (number), SUB_UID_COUNT (number)
The default values for SUB_UID_MIN, SUB_UID_MAX, SUB_UID_COUNT are respectively 100000, 600100000 and 65536.
SYS_GID_MAX (number), SYS_GID_MIN (number)
The default value for SYS_GID_MIN (resp. SYS_GID_MAX) is 101 (resp. GID_MIN-1).
SYS_UID_MAX (number), SYS_UID_MIN (number)
The default value for SYS_UID_MIN (resp. SYS_UID_MAX) is 101 (resp. UID_MIN-1).
UID_MAX (number), UID_MIN (number)
The default value for UID_MIN (resp. UID_MAX) is 1000 (resp. 60000).
UMASK (number)
useradd and newusers use this mask to set the mode of the home directory they create if HOME_MODE is not set.
It is also used by pam_umask as the default umask value.
