samusrgrp - add or remove users from groups in SAM database files

       This program was written by Petter N Hagen.

       This manual page was written by Javier Fernandez-Sanguino  <jfs@debian.org>,  for  the  Debian  GNU/Linux
       system (but may be used by others).

                                                 6th August 2014                                    SAMUSRGRP(8)

       This  manual  page  documents briefly the samusrgrp command.  This manual page was written for the Debian
       distribution because the original program does not have a manual page.

       samusrgrp is a non-interactive command line utility that can add or remove a user from a local group that
       exists in the SAM user database of a Microsoft Windows system (Windows  NT,  2000,  XP,  Vista,  7,  8.1,
       etc.).   This  file  is usually located at \WINDOWS\system32\config\SAM on the file system of a Microsoft
       Windows Operating System

       On success, the program does not output any informatin and the exit code is 0.

       The binary program supports multiple names. If it is called named samusrtogrp it will assume -a mode (add
       user). If it is called named samusrfromgrp it will assume -r mode (remove user).

samusrgrp-a-utheboss-g0x220SAMFILE
              Adds a user named 'theboss' to the group 0x220 (Administrators)

       samusrgrp-a-u0x3ea-g0x221SAMFILE
              Adds a user with the id '0x3aa' to the group 0x221 (Users)

       samusrgrp-r-u0x3ff-g0x221SAMFILE
              Remove a user with the id '0x3ff' from the group 0x221 (Users)

       If the username includes international (non-ASCII) characters the program will not (usually) find it. Use
       the RID number instead.

-h     Show summary of options.

       -a     The user is added to the group.  This option has to be followed by -u and -g .

       -r     The user is removed from the group.  This option has to be followed by -u and -g .

       -u<user>
              User to change. The user value can be provided as a username, or a RID number in  hexadecimal  (if
              the  username  is  preceded with '0x'). Usernames including international characters will probably
              not work.

       -g<group>
              Group to change. The group can only be given as a group number, in hexadecimal, preceded with with
              '0x'.

       -l     Lists the groups in the SAM database.

       -L     Lists the groups in the SAM database as well as their members.

       -s     Print the machine SID.

       -H     Output human readable output. The program by default will  print  a  parsable  table  unless  this
              option is used.

       -N     Do not allocate more information, only allow the editing of existing values with same size.

       -E     Do not expand the hive file (safe mode).

       -t     Print debug information of allocated blocks.

       -v     Print verbose information and debug messages.
