NOME
userdel - Rimuove l'account di un utente ed i file relativiSINOSSI
- userdel [opzioni] LOGIN
DESCRIZIONE
- The userdel command modifies the system account files, deleting all entries that refer to the user name LOGIN. The named user must exist.
OPZIONI
Il comando userdel accetta le seguenti opzioni:
-f, --force
- This option forces the removal of the user account, even if the user is still logged in. It also forces userdel to remove the user's home directory and mail spool, even if another user uses the same home directory or if the mail spool is not owned by the specified user. If USERGROUPS_ENAB is defined to yes in /etc/login.defs and if a group exists with the same name as the deleted user, then this group will be removed, even if it is still the primary group of another user.
Note: This option is dangerous and may leave your system in an inconsistent state.
-h, --help
- Mostra un messaggio di aiuto ed esce.
-r, --remove
- I file nella home directory dell'utente verranno rimossi insieme alla home directory stessa. I file collocati in altri file system dovranno essere ricercati e rimossi manualmente.
The mail spool is defined by the MAIL_DIR variable in the login.defs file.
CONFIGURATION
The following configuration variables in /etc/login.defs change the behavior of this tool:
MAIL_DIR (string)
- The mail spool directory. This is needed to manipulate the mailbox when its corresponding user account is modified or deleted. If not specified, a compile-time default is used.
MAIL_FILE (string)
- Defines the location of the users mail spool files relatively to their home directory.
The MAIL_DIR and MAIL_FILE variables are used by useradd, usermod, and userdel to create, move, or delete the user's mail spool.
If MAIL_CHECK_ENAB is set to yes, they are also used to define the MAIL environment variable.
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.
USERDEL_CMD (string)
- If defined, this command is run when removing a user. It should remove any at/cron/print jobs etc. owned by the user to be removed (passed as the first argument).
USERGROUPS_ENAB (boolean)
- Enable setting of the umask group bits to be the same as owner bits (examples: 022 -> 002, 077 -> 007) for non-root users, if the uid is the same as gid, and username is the same as the primary group name.
If set to yes, userdel will remove the user's group if it contains no more members, and useradd will create by default a group with the name of the user.

AVVISI/CAVEAT
userdel non permetterà di rimuovere alcun account se l'utente è attualmente connesso. Occorre uccidere qualunque processo in esecuzione che appartenga ad un account che si sta rimuovendo. Non è possibile rimuovere nessun attributo NIS su un client NIS.
Non è possibile rimuovere nessun attributo NIS su un client NIS. Questo deve essere fatto sul server NIS.
If USERGROUPS_ENAB is defined to yes in /etc/login.defs, userdel will delete the group with the same name as the user. To avoid inconsistencies in the passwd and group databases, userdel will check that this group is not used as a primary group for another user, and will just warn without deleting the user otherwise. The -f option can force the deletion of this group.
