'useradd' takes care of all that. It will also add the default directory and files in the new home directory and add the appropriate entries into /etc/passwd and /etc/shadow. No need for a counter. See previous comments for more information.

If you have to use a counter, these constructs will work also.

Code:
i=$userid
i=$(($i + 1))
#OR
let i=$userid
let i=++i;

But, then you'll have to find the highest UID and GID values in /etc/passwd for regular users. That will involve reading /etc/login.defs to get UID_MIN, UID_MAX, GID_MIN, GID_MAX and reading all of /etc/passwd for maximum valid UID and GID values. It's just not worth it. 'useradd' is much easier. To create password run 'passwd $user' after 'useradd'. So that's...

Code:
# if $dept doesn't exist
#   create new group with 'groupadd'
#   gid = dept's GID
#   create dir for dept
#   'chgrp' for dir of dept
# else
#   gid = dept's GID
# fi
useradd -m -d "/home/$dept/$user" -g $gid -K UMASK=026
passwd $user

pdebuild-user-mode-linux

pdebuild-user-mode-linux(1)					     pbuilder					       pdebuild-user-mode-linux(1)

NAME

       pdebuild-user-mode-linux - pbuilder-user-mode-linux way of doing debuild

SYNOPSIS

       pdebuild-user-mode-linux [pdebuild-user-mode-linux options] -- [pbuilder-user-mode-linux options]

DESCRIPTION

       A  convenience  program	for  pbuilder-user-mode-linux which invokes pbuilder after obtaining appropriate root privilege in a Debian source
       directory.  One must be inside the source tree containing the debian directory, in order to make it work.

PDEBUILD OPTIONS

       --buildsourceroot [fakeroot]
	      The command used to gain root privilege for invoking dpkg-buildpackage

       --auto-debsign

	      Invoke debsign at the end of pdebuild process.

       --debsign-k [key-id]

	      Pass -k option to debsign to specify which keyid to sign.

       --buildresult [Directory for build results]

	      The place which build result is stored.

       --configfile [Extra config file to use]

	      The configuration file is used, but not passed on to pbuilder-user-mode-linux.

       --debbuildopts [options to pass to dpkg-buildpackage]

	      The space-delimited list of options are passed to dpkg-buildpackage.  This option appends to pbuilder option --debbuildopts and  may
	      also be used to reset the list of options by passing the empty string.

       --use-pdebuild-internal
	      Uses a different implementation of pdebuild, which calls clean and build inside the chroot, using bind-mounts.

	      pdebuild-internal tries to run debian/rules clean inside the chroot.  To achieve the goal, the working directory is passed on inside
	      the chroot, in the form of bind-mounting and debuild is run.

	      This option will not protect the working directory and its parent directories from the build scripts.

       -- [pbuilder options]

	      After the -- symbol, an arbitrary number of pbuilder options can be specified.  See  pbuilder-user-mode-linux.1  for  full  list	of
	      options.

	      There is an exception that --buildresult needs to be specified as pdebuild option before the -- to be effective.

FILES

       /etc/pbuilderrc
	      The configuration file for pbuilder-user-mode-linux, used in pdebuild-user-mode-linux.

       /usr/share/pbuilder/pbuilderrc
	      The default configuration file for pbuilder-user-mode-linux, used in pdebuild-user-mode-linux.

       ${HOME}/.pbuilderrc
	      Configuration file for pbuilder-user-mode-linux, used in pdebuild-user-mode-linux, overrides what is written in /etc/pbuilderrc
