USERNEU(8) User Contributed Perl Documentation USERNEU(8)NAMEuserneu - A perl script to automatically create a batch of user
accounts
SYNOPSISuserneu [ -dhrsy ] [ -i input file ] [ -g primary group ]
[ -b [base directory for $HOME] ] [ -S [smbpasswd binary] ] [ -o [Out‐
put file] ] [ -m [minimum password length] ] [ -x [maximum pass‐
word length] ] [ -D [descriptors] ] [ -G [member groups] ]
[ -t [delimiter] ]
DESCRIPTIONuserneu processes a list of usernames and other information and creates
user accounts based on that. The available command line options are:
-d Enable the "dupe engine" which tries to "bruteforce" a username
that doesn't exist yet by appending one or two random characters
to already existing usernames it encounters. This is disabled by
default.
-h Display usage information.
-r Create strong passwords which means completely random strings of
misc case letters, special characters and numbers with a length of
10 characters (if no different length is specified using the -m
and -x switches). By default this is disabled and the script cre‐
ates passwords that are only composed of random lowercase letters
with a length of 8 characters.
-s Create Samba accounts in addition to traditional unix accounts. By
default this is disabled.
-y Append the "school year" to the GECOS field which is the period
between some day in September and some day in July and is there‐
fore composed of two calender years. I only included this because
I originally wrote this script for creating user accounts on my
school's network. If you need this option you probably know what
I'm talking about, if not you can safely ignore this as it is dis‐
abled by default anyway.
-i [input file]
This option is only relevant if the script is called as userneu.
It takes the location of the input file from which to read the
user information as argument.
-g [primary group]
Specify the primary group for the users to be created, defaults to
'users'.
-G [member group1;member group2;...]
Specify a semicolon separated list of member groups for the users
to be created.
-B [directory]
Specify the directory where the home directories of the created
users will be placed. Defaults to "/home/$group" where $group is
the primary group of the users.
-S [location of smbpasswd(8)]
Specify the location of smbpasswd(8). Defaults to
"/usr/local/bin/smbpasswd". This implies -s.
-o [output file]
Specify the location of the output file in which account informa‐
tion is stored. Defaults to 'useraccounts' CAUTION: This file con‐
tains cleartext passwords and should be well protected. Although
the script changes it's mode to 0600 it is no good idea to keep it
arround longer than needed.
-m [minimum password length]
Specify the minimum password length. This overrides the default
value of 8 characters (no -r option given) or 10 characters (-r
option given).
-x [maximum passsword length]
Specify the maximum password length. This overrides the default
value of 8 characters (no -r option given) or 10 characters (-r
option given).
-D [descriptor1;descriptor2;...]
Specify a semicolon separated list of descriptors for the fields
in the input. The length of this list has to match the actual
fields being present.
-f [configuration file
Specify the location of the configuration file. Defaults to
/etc/userneu.conf.
-t [delimiter]
Specify the delimiter for the fields in the input file as perl
regular expression (slash delimited). The default is "/\t/", which
means the fields are separated by tabs. This is only relevant if
the script is called as 'userneu'.
