Command line options have been fashioned to be similar -to those used by the Sun/shadow commands: useradd, usermod, userdel, -groupadd, groupmod, groupdel, but combines all operations within the -single command `pw'. - -User add mode also provides a means of easily setting system useradd -defaults (see pw.conf.5), so that adding a user is as easy as issuing -the command "pw useradd <loginid>". Creation of a unique primary -group for each user and automatic membership in secondary groups -is fully supported. - -This program may be FreeBSD specific, but should be trivial to port to -other bsd4.4 variants. - -Author and maintainer: David L.

superuser an easy to use and standardized way of adding, -modifying and removing users and groups. -Note that -.Nm -only operates on the local user and group files. -.Tn NIS -users and groups must be -maintained on the -.Tn NIS -server. -The -.Nm -utility handles updating the -.Pa passwd , -.Pa master.passwd , -.Pa group -and the secure and insecure -password database files, and must be run as root. -.Pp -The first one or two keywords provided to -.Nm -on the command line provide the context for the remainder of the arguments. -The keywords -.Ar user -and -.Ar group -may be combined with -.Ar add , -.Ar del , -.Ar mod , -.Ar show , -or -.Ar next -in any order. -(For example, -.Ar showuser , -.Ar usershow , -.Ar show user , -and -.Ar user show -all mean the same thing.) -This flexibility is useful for interactive scripts calling -.Nm -for user and group database manipulation. -Following these keywords, you may optionally specify the user or group name or numeric -id as an alternative to using the -.Fl n Ar name , -.Fl u Ar uid , -.Fl g Ar gid -options. -.Pp -The following flags are common to most or all modes of operation: -.Pp -.Bl -tag -width "-G grouplist" -.It Fl V Ar etcdir -This flag sets an alternate location for the password, group and configuration files, -and may be used to maintain a user/group database in an alternate location. -If this switch is specified, the system -.Pa /etc/pw.conf -will not be sourced for default configuration data, but the file pw.conf in the -specified directory will be used instead (or none, if it does not exist). -The -.Fl C -flag may be used to override this behaviour. -As an exception to the general rule where options must follow the operation -type, the -.Fl V -flag may be used on the command line before the operation keyword. -.It Fl C Ar config -By default, -.Nm -reads the file -.Pa /etc/pw.conf -to obtain policy information on how new user accounts and groups are to be created. -The -.Fl C -option specifies a different configuration file. -While most of the contents of the configuration file may be overridden via -command-line options, it may be more convenient to keep standard information in a -configuration file. -.It Fl q -Use of this option causes -.Nm -to suppress error messages, which may be useful in interactive environments where it -is preferable to interpret status codes returned by -.Nm -rather than messing up a carefully formatted display. -.It Fl N -This option is available in -.Ar add -and -.Ar modify -operations, and tells -.Nm -to output the result of the operation without updating the user or group -databases. -You may use the -.Fl P -option to switch between standard passwd and readable formats. -.It Fl Y -Using this option with any of the update modes causes -.Nm -to run -.Xr make 1 -after changing to the directory -.Pa /var/yp . -This is intended to allow automatic updating of -.Tn NIS -database files. -If separate passwd and group files are being used by -.Tn NIS , -then use the -.Fl y Ar path -option to specify the location of the -.Tn NIS -passwd database so that -.Nm -will concurrently update it with the system password -databases. -.El -.Sh USER OPTIONS -The following options apply to the -.Ar useradd -and -.Ar usermod -commands: -.Pp -.Bl -tag -width "-G grouplist" -.It Fl n Ar name -Specify the user/account name. -.It Fl u Ar uid -Specify the user/account numeric id. -.Pp -Usually, you only need to provide one or the other of these options, as the account -name will imply the uid, or vice versa. -However, there are times when you need to provide both. -For example, when changing the uid of an existing user with -.Ar usermod , -or overriding the default uid when creating a new account. -If you wish -.Nm -to automatically allocate the uid to a new user with -.Ar useradd , -then you should -.Em not -use the -.Fl u -option. -You may also provide either the account or userid immediately after the -.Ar useradd , -.Ar userdel , -.Ar usermod -or -.Ar usershow -keywords on the command line without using the -.Fl n -or -.Fl u -options. -.El -.Pp -.Bl -tag -width "-G grouplist" -.It Fl c Ar comment -This field sets the contents of the passwd GECOS field, which normally contains up -to four comma-separated fields containing the user's full name, office or location, -and work and home phone numbers. -These sub-fields are used by convention only, however, and are optional. -If this field is to contain spaces, you need to quote the comment itself with double -quotes -.Ql \&" . -Avoid using commas in this field as these are used as sub-field separators, and the -colon -.Ql \&: -character also cannot be used as this is the field separator for the passwd -file itself. -.It Fl d Ar dir -This option sets the account's home directory. -Normally, you will only use this if the home directory is to be different from the -default determined from -.Pa /etc/pw.conf -- normally -.Pa /home -with the account name as a subdirectory. -.It Fl e Ar date -Set the account's expiration date. -Format of the date is either a UNIX time in decimal, or a date in -.Ql dd-mmm-yy[yy] -format, where dd is the day, mmm is the month, either in numeric or alphabetic format -('Jan', 'Feb', etc) and year is either a two or four digit year. -This option also accepts a relative date in the form -.Ql \&+n[mhdwoy] -where -.Ql \&n -is a decimal, octal (leading 0) or hexadecimal (leading 0x) digit followed by the -number of Minutes, Hours, Days, Weeks, Months or Years from the current date at -which the expiration date is to be set. -.It Fl p Ar date -Set the account's password expiration date. -This field is similar to the account expiration date option, except that it -applies to forced password changes. -This is set in the same manner as the -.Fl e -option. -.It Fl g Ar group -Set the account's primary group to the given group. -.Ar group -may be defined by either its name or group number. -.It Fl G Ar grouplist -Set additional group memberships for an account. -.Ar grouplist -is a comma, space or tab-separated list of group names or group numbers. -The user's name is added to the group lists in -.Pa /etc/group , -and -removed from any groups not specified in -.Ar grouplist . -Note: a user should not be added to their primary group with -.Ar grouplist . -Also, group membership changes do not take effect for current user login -sessions, requiring the user to reconnect to be affected by the changes. -.It Fl L Ar class -This option sets the login class for the user being created. -See -.Xr login.conf 5 -and -.Xr passwd 5 -for more information on user login classes. -.It Fl m -This option instructs -.Nm -to attempt to create the user's home directory. -While primarily useful when adding a new account with -.Ar useradd , -this may also be of use when moving an existing user's home directory elsewhere on -the file system. -The new home directory is populated with the contents of the -.Ar skeleton -directory, which typically contains a set of shell configuration files that the -user may personalize to taste. -Files in this directory are usually named -.Pa dot . Ns Aq Ar config -where the -.Pa dot -prefix will be stripped. -When -.Fl m -is used on an account with -.Ar usermod , -existing configuration files in the user's home directory are -.Em not -overwritten from the skeleton files. -.Pp -When a user's home directory is created, it will by default be a subdirectory of the -.Ar basehome -directory as specified by the -.Fl b -option (see below), bearing the name of the new account. -This can be overridden by the -.Fl d -option on the command line, if desired. -.It Fl M Ar mode -Create the user's home directory with the specified -.Ar mode , -modified by the current -.Xr umask 2 . -If omitted, it is derived from the parent process' -.Xr umask 2 . -This option is only useful in combination with the -.Fl m -flag. -.It Fl k Ar dir -Set the -.Ar skeleton -directory, from which basic startup and configuration files are copied when -the user's home directory is created. -This option only has meaning when used with the -.Fl d -or -.Fl m -flags. -.It Fl s Ar shell -Set or changes the user's login shell to -.Ar shell . -If the path to the shell program is omitted, -.Nm -searches the -.Ar shellpath -specified in -.Pa /etc/pw.conf -and fills it in as appropriate. -Note that unless you have a specific reason to do so, you should avoid -specifying the path - this will allow -.Nm -to validate that the program exists and is executable. -Specifying a full path (or supplying a blank "" shell) avoids this check -and allows for such entries as -.Pa /nonexistent -that should be set for accounts not intended for interactive login. -.It Fl h Ar fd -This option provides a special interface by which interactive scripts can -set an account password using -.Nm . -Because the command line and environment are fundamentally insecure mechanisms -by which programs can accept information, -.Nm -will only allow setting of account and group passwords via a file descriptor -(usually a pipe between an interactive script and the program). -.Ar sh , -.Ar bash , -.Ar ksh -and -.Ar perl -all possess mechanisms by which this can be done. -Alternatively, -.Nm -will prompt for the user's password if -.Fl h Ar 0 -is given, nominating -.Em stdin -as the file descriptor on which to read the password. -Note that this password will be read only once and is intended -for use by a script rather than for interactive use. -If you wish to have new password confirmation along the lines of -.Xr passwd 1 , -this must be implemented as part of an interactive script that calls -.Nm . -.Pp -If a value of -.Ql \&- -is given as the argument -.Ar fd , -then the password will be set to -.Ql \&* , -rendering the account inaccessible via password-based login. -.It Fl H Ar fd -Read an encrypted password string from the specified file descriptor. -This is like -.Fl h , -but the password should be supplied already encrypted in a form -suitable for writing directly to the password database. -.El -.Pp -It is possible to use -.Ar useradd -to create a new account that duplicates an existing user id. -While this is normally considered an error and will be rejected, the -.Fl o -option overrides the check for duplicates and allows the duplication of -the user id. -This may be useful if you allow the same user to login under -different contexts (different group allocations, different home -directory, different shell) while providing basically the same -permissions for access to the user's files in each account. -.Pp -The -.Ar useradd -command also has the ability to set new user and group defaults by using the -.Fl D -option. -Instead of adding a new user, -.Nm -writes a new set of defaults to its configuration file, -.Pa /etc/pw.conf . -When using the -.Fl D -option, you must not use either -.Fl n Ar name -or -.Fl u Ar uid -or an error will result. -Use of -.Fl D -changes the meaning of several command line switches in the -.Ar useradd -command. -These are: -.Bl -tag -width "-G grouplist" -.It Fl D -Set default values in -.Pa /etc/pw.conf -configuration file, or a different named configuration file if the -.Fl C Ar config -option is used. -.It Fl b Ar dir -Set the root directory in which user home directories are created. -The default value for this is -.Pa /home , -but it may be set elsewhere as desired. -.It Fl e Ar days -Set the default account expiration period in days. -Unlike use without -.Fl D , -the argument must be numeric, which specifies the number of days after creation when -the account is to expire. -A value of 0 suppresses automatic calculation of the expiry date. -.It Fl p Ar days -Set the default password expiration period in days. -.It Fl g Ar group -Set the default group for new users. -If a blank group is specified using -.Fl g Ar \&"" , -then new users will be allocated their own private primary group -with the same name as their login name. -If a group is supplied, either its name or uid may be given as an argument. -.It Fl G Ar grouplist -Set the default groups in which new users are granted membership. -This is a separate set of groups from the primary group, and you should avoid -nominating the same group as both primary and extra groups. -In other words, these extra groups determine membership in groups -.Em other than -the primary group. -.Ar grouplist -is a comma-separated list of group names or ids, and are always -stored in -.Pa /etc/pw.conf -by their symbolic names. -.It Fl L Ar class -This option sets the default login class for new users. -.It Fl k Ar dir -Set the default -.Em skeleton -directory, from which prototype shell and other initialization files are copied when -.Nm -creates a user's home directory. -See description of -.Fl k -for naming conventions of these files. -.It Xo -.Fl u Ar min , Ns Ar max , -.Fl i Ar min , Ns Ar max -.Xc -These options set the minimum and maximum user and group ids allocated for new accounts -and groups created by -.Nm . -The default values for each is 1000 minimum and 32000 maximum. -.Ar min -and -.Ar max -are both numbers, where max must be greater than min, and both must be between 0 -and 32767. -In general, user and group ids less than 100 are reserved for use by the system, -and numbers greater than 32000 may also be reserved for special purposes (used by -some system daemons). -.It Fl w Ar method -The -.Fl w -option sets the default method used to set passwords for newly created user accounts. -.Ar method -is one of: -.Pp -.Bl -tag -width random -offset indent -compact -.It no -disable login on newly created accounts -.It yes -force the password to be the account name -.It none -force a blank password -.It random -generate a random password -.El -.Pp -The -.Ql \&random -or -.Ql \&no -methods are the most secure; in the former case, -.Nm -generates a password and prints it to stdout, which is suitable where you issue -users with passwords to access their accounts rather than having the user nominate -their own (possibly poorly chosen) password. -The -.Ql \&no -method requires that the superuser use -.Xr passwd 1 -to render the account accessible with a password. -.It Fl y Ar path -This sets the pathname of the database used by -.Tn NIS -if you are not sharing -the information from -.Pa /etc/master.passwd -directly with -.Tn NIS . -You should only set this option for -.Tn NIS -servers. -.El -.Pp -The -.Ar userdel -command has only three valid options. -The -.Fl n Ar name -and -.Fl u Ar uid -options have already been covered above. -The additional option is: -.Bl -tag -width "-G grouplist" -.It Fl r -This tells -.Nm -to remove the user's home directory and all of its contents. -The -.Nm -utility errs on the side of caution when removing files from the system. -Firstly, it will not do so if the uid of the account being removed is also used by -another account on the system, and the 'home' directory in the password file is -a valid path that commences with the character -.Ql \&/ . -Secondly, it will only remove files and directories that are actually owned by -the user, or symbolic links owned by anyone under the user's home directory. -Finally, after deleting all contents owned by the user only empty directories -will be removed. -If any additional cleanup work is required, this is left to the administrator. -.El -.Pp -Mail spool files and crontabs are always removed when an account is deleted as these -are unconditionally attached to the user name. -Jobs queued for processing by -.Ar at -are also removed if the user's uid is unique and not also used by another account on the -system. -.Pp -The -.Ar usershow -command allows viewing of an account in one of two formats. -By default, the format is identical to the format used in -.Pa /etc/master.passwd -with the password field replaced with a -.Ql \&* . -If the -.Fl P -option is used, then -.Nm -outputs the account details in a more human readable form. -If the -.Fl 7 -option is used, the account details are shown in v7 format. -The -.Fl a -option lists all users currently on file. -Using -.Fl F -forces -.Nm -to print the details of an account even if it does not exist. -.Pp -The command -.Ar usernext -returns the next available user and group ids separated by a colon. -This is normally of interest only to interactive scripts or front-ends -that use -.Nm . -.Sh GROUP OPTIONS -The -.Fl C -and -.Fl q -options (explained at the start of the previous section) are available -with the group manipulation commands. -Other common options to all group-related commands are: -.Bl -tag -width "-m newmembers" -.It Fl n Ar name -Specify the group name. -.It Fl g Ar gid -Specify the group numeric id. -.Pp -As with the account name and id fields, you will usually only need -to supply one of these, as the group name implies the uid and vice -versa. -You will only need to use both when setting a specific group id -against a new group or when changing the uid of an existing group. -.It Fl M Ar memberlist -This option provides an alternative way to add existing users to a -new group (in groupadd) or replace an existing membership list (in -groupmod). -.Ar memberlist -is a comma separated list of valid and existing user names or uids. -.It Fl m Ar newmembers -Similar to -.Fl M , -this option allows the -.Em addition -of existing users to a group without replacing the existing list of -members. -Login names or user ids may be used, and duplicate users are -silently eliminated. -.It Fl d Ar oldmembers -Similar to -.Fl M , -this option allows the -.Em deletion -of existing users from a group without replacing the existing list of -members. -Login names or user ids may be used, and duplicate users are -silently eliminated. -.El -.Pp -.Ar groupadd -also has a -.Fl o -option that allows allocation of an existing group id to a new group. -The default action is to reject an attempt to add a group, and this option overrides -the check for duplicate group ids. -There is rarely any need to duplicate a group id. -.Pp -The -.Ar groupmod -command adds one additional option: -.Pp -.Bl -tag -width "-m newmembers" -.It Fl l Ar name -This option allows changing of an existing group name to -.Ql \&name . -The new name must not already exist, and any attempt to duplicate an existing group -name will be rejected. -.El -.Pp -Options for -.Ar groupshow -are the same as for -.Ar usershow , -with the -.Fl g Ar gid -replacing -.Fl u Ar uid -to specify the group id. -The -.Fl 7 -option does not apply to the -.Ar groupshow -command. -.Pp -The command -.Ar groupnext -returns the next available group id on standard output. -.Sh USER LOCKING -The -.Nm -utility -supports a simple password locking mechanism for users; it works by -prepending the string -.Ql *LOCKED* -to the beginning of the password field in -.Pa master.passwd -to prevent successful authentication. -.Pp -The -.Ar lock -and -.Ar unlock -commands take a user name or uid of the account to lock or unlock, -respectively. -The -.Fl V , -.Fl C , -and -.Fl q -options as described above are accepted by these commands. -.Sh NOTES -For a summary of options available with each command, you can use -.Dl pw [command] help -For example, -.Dl pw useradd help -lists all available options for the useradd operation. -.Pp -The -.Nm -utility allows 8-bit characters in the passwd GECOS field (user's full name, -office, work and home phone number subfields), but disallows them in -user login and group names. -Use 8-bit characters with caution, as connection to the Internet will -require that your mail transport program supports 8BITMIME, and will -convert headers containing 8-bit characters to 7-bit quoted-printable -format. -.Xr sendmail 8 -does support this. -Use of 8-bit characters in the GECOS field should be used in -conjunction with the user's default locale and character set -and should not be implemented without their use. -Using 8-bit characters may also affect other -programs that transmit the contents of the GECOS field over the -Internet, such as -.Xr fingerd 8 , -and a small number of TCP/IP clients, such as IRC, where full names -specified in the passwd file may be used by default. -.Pp -The -.Nm -utility writes a log to the -.Pa /var/log/userlog -file when actions such as user or group additions or deletions occur. -The location of this logfile can be changed in -.Xr pw.conf 5 . -.Sh FILES -.Bl -tag -width

-.Nm pw.conf -.Nd format of the pw.conf configuration file -.Sh DESCRIPTION -The file -.In /etc/pw.conf -contains configuration data for the -.Xr pw 8 -utility. -The -.Xr pw 8 -utility is used for maintenance of the system password and group -files, allowing users and groups to be added, deleted and changed. -This file may be modified via the -.Xr pw 8 -command using the -.Ar useradd -command and the -.Fl D -option, or by editing it directly with a text editor. -.Pp -Each line in -.Pa /etc/pw.conf -is treated either a comment or as configuration data; -blank lines and lines commencing with a -.Ql \&# -character are considered comments, and any remaining lines are -examined for a leading keyword, followed by corresponding data. -.Pp -Keywords recognized by -.Xr pw 8 -are: -.Bl -tag -width password_days -offset indent -compact -.It defaultpasswd -affect passwords generated for new users -.It reuseuids -reuse gaps in uid sequences -.It reusegids -reuse gaps in gid sequences -.It nispasswd -path to the -.Tn NIS -passwd database -.It skeleton -where to obtain default home contents -.It newmail -mail to send to new users -.It logfile -log user/group modifications to this file -.It home -root directory for home directories -.It homemode -permissions for home directory -.It shellpath -paths in which to locate shell programs -.It shells -list of valid shells (without path) -.It defaultshell -default shell (without path) -.It defaultgroup -default group -.It extragroups -add new users to this groups -.It defaultclass -place new users in this login class -.It minuid -.It maxuid -range of valid default user ids -.It mingid -.It maxgid -range of valid default group ids -.It expire_days -days after which account expires -.It password_days -days after which password expires -.El -.Pp -Valid values for -.Ar defaultpasswd -are: -.Bl -tag -width password_days -offset indent -compact -.It no -disable login on newly created accounts -.It yes -force the password to be the account name -.It none -force a blank password -.It random -generate a random password -.El -.Pp -The second and third options are insecure and should be avoided if -possible on a publicly accessible system. -The first option requires that the superuser run -.Xr passwd 1 -to set a password before the account may be used. -This may also be useful for creating administrative accounts. -The final option causes -.Xr pw 8 -to respond by printing a randomly generated password on stdout. -This is the preferred and most secure option. -The -.Xr pw 8 -utility also provides a method of setting a specific password for the new -user via a filehandle (command lines are not secure). -.Pp -Both -.Ar reuseuids -and -.Ar reusegids -determine the method by which new user and group id numbers are -generated. -A -.Ql \&yes -in this field will cause -.Xr pw 8 -to search for the first unused user or group id within the allowed -range, whereas a -.Ql \&no -will ensure that no other existing user or group id within the range -is numerically lower than the new one generated, and therefore avoids -reusing gaps in the user or group id sequence that are caused by -previous user or group deletions. -Note that if the default group is not specified using the -.Ar defaultgroup -keyword, -.Xr pw 8 -will create a new group for the user and attempt to keep the new -user's uid and gid the same. -If the new user's uid is currently in use as a group id, then the next -available group id is chosen instead. -.Pp -On -.Tn NIS -servers which maintain a separate passwd database to -.Pa /etc/master.passwd , -this option allows the additional file to be concurrently updated -as user records are added, modified or removed. -If blank or set to 'no', no additional database is updated. -An absolute pathname must be used. -.Pp -The -.Ar skeleton -keyword nominates a directory from which the contents of a user's -new home directory is constructed. -This is -.Pa /usr/share/skel -by default. -The -.Xr pw 8 Ns 's -.Fl m -option causes the user's home directory to be created and populated -using the files contained in the -.Ar skeleton -directory. -.Pp -To send an initial email to new users, the -.Ar newmail -keyword may be used to specify a path name to a file containing -the message body of the message to be sent. -To avoid sending mail when accounts are created, leave this entry -blank or specify -.Ql \&no . -.Pp -The -.Ar logfile -option allows logging of password file modifications into the -nominated log file. -To avoid creating or adding to such a logfile, then leave this -field blank or specify -.Ql \&no . -.Pp -The -.Ar home -keyword is mandatory. -This specifies the location of the directory in which all new user -home directories are created. -.Pp -The -.Ar homemode -keyword is optional. -It specifies the creation mask of the user's home directory and is modified by -.Xr umask 2 . -.Pp -The -.Ar shellpath -keyword specifies a list of directories - separated by colons -.Ql \&: -- which contain the programs used by the login shells. -.Pp -The -.Ar shells -keyword specifies a list of programs available for use as login -shells. -This list is a comma-separated list of shell names which should -not contain a path. -These shells must exist in one of the directories nominated by -.Ar shellpath . -.Pp -The -.Ar defaultshell -keyword nominates which shell program to use for new users when -none is specified on the -.Xr pw 8 -command line. -.Pp -The -.Ar defaultgroup -keyword defines the primary group (the group id number in the -password file) used for new accounts. -If left blank, or the word -.Ql \&no -is used, then each new user will have a corresponding group of -their own created automatically. -This is the recommended procedure for new users as it best secures each -user's files against interference by other users of the system -irrespective of the -.Em umask -normally used by the user. -.Pp -The -.Ar extragroups -keyword provides an automatic means of placing new users into groups within -the -.Pa /etc/groups -file. -This is useful where all users share some resources, and is preferable -to placing users into the same primary group. -The effect of this keyword can be overridden using the -.Fl G -option on the -.Xr pw 8 -command line. -.Pp -The -.Ar defaultclass -field determines the login class (See -.Xr login.conf 5 ) -that new users will be allocated unless overwritten by -.Xr pw 8 . -.Pp -The -.Ar minuid , -.Ar maxuid , -.Ar mingid , -.Ar maxgid -keywords determine the allowed ranges of automatically allocated user -and group id numbers. -The default values for both user and group ids are 1000 and 32000 as -minimum and maximum respectively. -The user and group id's actually used when creating an account with -.Xr pw 8 -may be overridden using the -.Fl u -and -.Fl g -command line options. -.Pp -The -.Ar expire_days -and -.Ar password_days -are used to automatically calculate the number of days from the date -on which an account is created when the account will expire or the -user will be forced to change the account's password. -A value of -.Ql \&0 -in either field will disable the corresponding (account or password) -expiration date. -.Sh LIMITS -The maximum line length of -.Pa /etc/pw.conf -is 1024 characters. -Longer lines will be skipped and treated -as comments. -.Sh FILES
