useradd: create a new user or update default new user information

Useradd is a low level utility for adding users. On Debian, administrators should usually use adduser(8) instead. When invoked without the -D option, the useradd command creates a new user account using the values specified on the. Make sure that you do not use spaces between any of the group names. If there is a space, the useradd command will think that you are specifying the username to use. For example, if we were to create our user called pimylifeup and wanted to add it to multiple groups such as admins, www-data, and git. Useradd -G admins,www-data,git pimylifeup. Every Mac has at least one account that allows you to use your computer. However, if multiple people need to use your Mac, you probably don’t want to share the same account, which can be like trying to share the same pair of pants. To protect your files and settings, you should create a separate.

By default the command useradd doesn't create home directories, but for a daemon I recommend you to use the system option and change the shell to a non-existent one so no one can login with said account (in ssh for example): sudo useradd -r -s /bin/false USERNAME. MacOS uses a directory service to administrate users. The adduser command equivalent for Mac is: dscl.create /User/USERNAMEHERE You may need admin privledges, therefore sudo will be needed like so.create /User/USERNAMEHERE Followed.

Useradd For Mac Catalina

Command to display useradd manual in Linux: $ man 8 useradd

NAME

useradd - create a new user or update default new user information

SYNOPSIS

By default, a group will also be created for the new user (see-g,-N,-U, andUSERGROUPS_ENAB).

OPTIONS

The options which apply to theuseraddcommand are:

-b, --base-dirBASE_DIR

The default base directory for the system if-dHOME_DIRis not specified.BASE_DIRis concatenated with the account name to define the home directory. If the-moption is not used,BASE_DIRmust exist.

If this option is not specified,useraddwill use the base directory specified by theHOMEvariable in/etc/default/useradd, or/homeby default.

Need for speed mac 2016. -c, --commentCOMMENT

-d, --home-dirHOME_DIR

LOGINname toBASE_DIRand use that as the login directory name. The directoryHOME_DIRdoes not have to exist but will not be created if it is missing.

-D, --defaults

-e, --expiredateEXPIRE_DATE

The date on which the user account will be disabled. The date is specified in the formatYYYY-MM-DD.

If not specified,useraddwill use the default expiry date specified by theEXPIREvariable in/etc/default/useradd, or an empty string (no expiry) by default.

-f, --inactiveINACTIVE

The number of days after a password expires until the account is permanently disabled. A value of 0 disables the account as soon as the password has expired, and a value of -1 disables the feature.

If not specified,useraddwill use the default inactivity period specified by theINACTIVEvariable in/etc/default/useradd, or -1 by default.

-g, --gidGROUP

The group name or number of the user's initial login group. The group name must exist. A group number must refer to an already existing group.

If not specified, the behavior ofuseraddwill depend on theUSERGROUPS_ENABvariable in/etc/login.defs. If this variable is set toyes(or-U/--user-groupis specified on the command line), a group will be created for the user, with the same name as her loginname. If the variable is set tono(or-N/--no-user-groupis specified on the command line), useradd will set the primary group of the new user to the value specified by theGROUPvariable in/etc/default/useradd, or 100 by default.

-G, --groupsGROUP1[,GROUP2,..[,GROUPN]]]

Display help message and exit.

-k, --skelSKEL_DIR

The skeleton directory, which contains files and directories to be copied in the user's home directory, when the home directory is created byuseradd.

This option is only valid if the-m(or--create-home) option is specified.

If this option is not set, the skeleton directory is defined by theSKELvariable in/etc/default/useraddor, by default,/etc/skel.

If possible, the ACLs and extended attributes are copied.

-K, --keyKEY=VALUE

Overrides/etc/login.defsdefaults (UID_MIN,UID_MAX,UMASK,PASS_MAX_DAYSand others).

Example:-KPASS_MAX_DAYS=-1can be used when creating system account to turn off password aging, even though system account has no password at all. Multiple-Koptions can be specified, e.g.:-KUID_MIN=100-KUID_MAX=499

-l, --no-log-init

Do not add the user to the lastlog and faillog databases.

By default, the user's entries in the lastlog and faillog databases are reset to avoid reusing the entry from a previously deleted user.

For the compatibility with previous Debian'suseradd, the-Ooption is also supported.

-m, --create-home

Create the user's home directory if it does not exist. The files and directories contained in the skeleton directory (which can be defined with the-koption) will be copied to the home directory.

By default, if this option is not specified andCREATE_HOMEis not enabled, no home directories are created.

-M, --no-create-home

CREATE_HOME) is set toyes.

-N, --no-user-group

Do not create a group with the same name as the user, but add the user to the group specified by the-goption or by theGROUPvariable in/etc/default/useradd.

The default behavior (if the-g,-N, and-Uoptions are not specified) is defined by theUSERGROUPS_ENABvariable in/etc/login.defs.

-o, --non-unique

Allow the creation of a user account with a duplicate (non-unique) UID.

This option is only valid in combination with the-uoption.

Google maps app for mac.

-p, --passwordPASSWORD

The encrypted password, as returned bycrypt(3). The default is to disable the password.

Note:This option is not recommended because the password (or encrypted password) will be visible by users listing the processes.

You should make sure the password respects the system's password policy.

-r, --system

Create a system account.

System users will be created with no aging information in/etc/shadow, and their numeric identifiers are chosen in theSYS_UID_MIN-SYS_UID_MAXrange, defined in/etc/login.defs, instead ofUID_MIN-UID_MAX(and theirGIDcounterparts for the creation of groups).

Note thatuseraddwill not create a home directory for such a user, regardless of the default setting in/etc/login.defs(CREATE_HOME). You have to specify the-moptions if you want a home directory for a system account to be created.

-R, --rootCHROOT_DIR

The name of the user's login shell. The default is to leave this field blank, which causes the system to select the default login shell specified by theSHELLvariable in/etc/default/useradd, or an empty string by default.

-u, --uidUID

The numerical value of the user's ID. This value must be unique, unless the-ooption is used. The value must be non-negative. The default is to use the smallest ID value greater than or equal toUID_MINand greater than every other user.

See also the-roption and theUID_MAXdescription.

-U, --user-group

Create a group with the same name as the user, and add the user to this group.

The default behavior (if the-g,-N, and-Uoptions are not specified) is defined by theUSERGROUPS_ENABvariable in/etc/login.defs.

-Z, --selinux-userSEUSER

Changing the default values

When invoked with only the-Doption,useraddwill display the current default values. When invoked with-Dplus other options,useraddwill update the default values for the specified options. Valid default-changing options are:

-b, --base-dirBASE_DIR

The path prefix for a new user's home directory. The user's name will be affixed to the end ofBASE_DIRto form the new user's home directory name, if the-doption is not used when creating a new account.

This option sets theHOMEvariable in/etc/default/useradd.

-e, --expiredateEXPIRE_DATE

The date on which the user account is disabled.

This option sets theEXPIREvariable in/etc/default/useradd.

-f, --inactiveINACTIVE

The number of days after a password has expired before the account will be disabled.

This option sets theINACTIVEvariable in/etc/default/useradd.

-g, --gidGROUP

The group name or ID for a new user's initial group (when the-N/--no-user-groupis used or when theUSERGROUPS_ENABvariable is set tonoin/etc/login.defs). The named group must exist, and a numerical group ID must have an existing entry.

This option sets theGROUPvariable in/etc/default/useradd.

-s, --shellSHELL

The name of a new user's login shell.

This option sets theSHELLvariable in/etc/default/useradd.

NOTES

The system administrator is responsible for placing the default user files in the/etc/skel/directory (or any other skeleton directory specified in/etc/default/useraddor on the command line).

CAVEATS

You may not add a user to a NIS or LDAP group. This must be performed on the corresponding server.

Similarly, if the username already exists in an external user database such as NIS or LDAP,useraddwill deny the user account creation request.

It is usually recommended to only use usernames that begin with a lower case letter or an underscore, followed by lower case letters, digits, underscores, or dashes. They can end with a dollar sign. In regular expression terms: [a-z_][a-z0-9_-]*[$]?

On Debian, the only constraints are that usernames must neither start with a dash ('-') nor plus ('+') nor tilde ('~') nor contain a colon (':'), a comma (','), or a whitespace (space: ' ', end of line: 'n', tabulation: 't', etc.). Note that using a slash ('/') may break the default algorithm for the definition of the user's home directory.

Usernames may only be up to 32 characters long.

CONFIGURATION

The following configuration variables in/etc/login.defschange the behavior of this tool:

CREATE_HOME (boolean)

Indicate if a home directory should be created by default for new users.

This setting does not apply to system users, and can be overridden on the command line.

GID_MAX (number), GID_MIN (number)

Range of group IDs used for the creation of regular groups byuseradd,groupadd, ornewusers.

The default value forGID_MIN(resp.GID_MAX) is 1000 (resp. 60000).

MAIL_DIR (string)

Amazon music for mac. MAC Music Cafe Live Music Held 9.27.20 In Middletown. The rules of replying: Be respectful. This is a space for friendly local discussions. No racist, discriminatory, vulgar or threatening. Live for Mac stands out as an excellent audio production and recording software that packs all the essential features you'd expect from an application of its kind and comes with a multitude of.

MAX_MEMBERS_PER_GROUP (number)

Maximum members per group entry. When the maximum is reached, a new group entry (line) is started in/etc/group(with the same name, same password, and same GID).

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)

The minimum number of days allowed between password changes. Any password changes attempted sooner than this will be rejected. If not specified, -1 will be assumed (which disables the restriction).

PASS_WARN_AGE (number)
