Each line holds a\nsingle value pair in the form option = value. Double or single quotes\nare allowed around the value, as is whitespace around the equals sign.\nComment lines must have a hash sign (#) in the first column.\n\nThe valid configuration options are:\n\nDSHELL The login shell to be used for all new users. Defaults to\n/bin/bash.\n\nDHOME The directory in which new home directories should be created.\nDefaults to /home.\n\nGROUPHOMES\nIf this is set to yes, the home directories will be created as\n/home/[groupname]/user. Defaults to no.\n\nLETTERHOMES\nIf this is set to yes, then the home directories created will\nhave an extra directory inserted which is the first letter of\nthe loginname. For example: /home/u/user. Defaults to no.\n\nSKEL The directory from which skeletal user configuration files\nshould be copied. Defaults to /etc/skel.\n\nFIRSTSYSTEMUID and LASTSYSTEMUID\nspecify an inclusive range of UIDs from which system UIDs can be\ndynamically allocated. Default to 100 - 999. Please note that\nsystem software, such as the users allocated by the base-passwd\npackage, may assume that UIDs less than 100 are unallocated.\n\nFIRSTUID and LASTUID\nspecify an inclusive range of UIDs from which normal user's UIDs\ncan be dynamically allocated. Default to 1000 - 59999.\n\nFIRSTSYSTEMGID and LASTSYSTEMGID\nspecify an inclusive range of GIDs from which system GIDs can be\ndynamically allocated. Default to 100 - 999.\n\nFIRSTGID and LASTGID\nspecify an inclusive range of GIDs from which normal group's\nGIDs can be dynamically allocated. Default to 1000 - 59999.\n\nUSERGROUPS\nIf this is set to yes, then each created user will be given\ntheir own group to use. If this is no, then each created user\nwill be placed in the group whose GID is USERSGID (see below).\nThe default is yes.\n\nUSERSGID\nIf USERGROUPS is no, then USERSGID is the GID given to all\nnewly-created users. The default value is 100.\n\nDIRMODE\nIf set to a valid value (e.g. 0755 or 755), directories created\nwill have the specified permissions as umask. Otherwise 0755 is\nused as default.\n\nSETGIDHOME\nIf this is set to yes, then home directories for users with\ntheir own group ( USERGROUPS=yes ) will have the setgid bit set.\nThis was the default setting for adduser versions << 3.13. Un-\nfortunately it has some bad side effects, so we no longer do\nthis per default. If you want it nevertheless you can still ac-\ntivate it here.\n\nQUOTAUSER\nIf set to a nonempty value, new users will have quotas copied\nfrom that user. The default is empty.\n\nNAMEREGEX\nUser and group names are checked against this regular expres-\nsion. If the name doesn't match this regexp, user and group cre-\nation in adduser is refused unless --force-badname is set. With\n--force-badname set, only weak checks are performed. The default\nis the most conservative ^[a-z][-a-z0-9]*$. When --system is\nspecified, NAMEREGEXSYSTEM is used instead.\n\nNAMEREGEXSYSTEM\nNames of system users are checked against this regular expres-\nsion. If --system is supplied and the name doesn't match this\nregexp, user creation in adduser is refused unless --force-bad-\nname is set. With --force-badname set, only weak checks are per-\nformed. The default is as for the default NAMEREGEX but also\nallowing uppercase letters.\n\nSKELIGNOREREGEX\nFiles in /etc/skel/ are checked against this regex, and not\ncopied to the newly created home directory if they match. This\nis by default set to the regular expression matching files left\nover from unmerged config files (dpkg-(old|new|dist)).\n\nADDEXTRAGROUPS\nSetting this to something other than 0 (the default) will cause\nadduser to add newly created non-system users to the list of\ngroups defined by EXTRAGROUPS (below).\n\nEXTRAGROUPS\nThis is the list of groups that new non-system users will be\nadded to. By default, this list is 'dialout cdrom floppy audio\nvideo plugdev users games'.\n", "subsections": [] }, "NOTES": { "content": "VALID NAMES\nadduser and addgroup enforce conformity to IEEE Std 1003.1-2001,\nwhich allows only the following characters to appear in group\nand user names: letters, digits, underscores, periods, at signs\n(@) and dashes. The name may no start with a dash. The \"$\" sign\nis allowed at the end of usernames (to conform to samba).\n\nAn additional check can be adjusted via the configuration param-\neter NAMEREGEX to enforce a local policy.\n", "subsections": [] }, "FILES": { "content": "/etc/adduser.conf\n", "subsections": [] }, "SEE ALSO": { "content": "addgroup(8), adduser(8), delgroup(8), deluser(8), deluser.conf(5)\n\nDebian GNU/Linux Version 3.118ubuntu5 adduser.conf(5)", "subsections": [] } } } }
