Missing some spaces. this may help:

Code:
#if [ $filesize-gt$3 ]; then
 if [ $filesize -gt $3 ]; then

---------- Post updated at 09:40 AM ---------- Previous update was at 09:33 AM ----------

found another one:
Code:
#if [ $1 -ne -b]; then
 if [ $1 -ne -b ]; then

Also I think you could improve your program's organization by using a case statement, and shift. That many if-else's is difficult to look through since what's happening now directly depends on a decision made 3 pages ago, better to break into smaller blocks where you can. Remember that an if - then - exit - fi is as good as an if - else, since you can branch just by quitting.

Code:
if [ "$#" -lt 4 ]
then
        echo "Requires at least 4 parameters"
        exit 1
fi

case "$1" in
"-b")
        echo "handle -b stuff here"
        ;;
"-g")
        echo "handle -g stuff here"
        ;;
*)
        echo "First parameter must be -b or -g"
        exit 1
        ;;
esac

shift
size1="$1"
shift
size2="$1"
shift

while [ "$#" -gt 0 ]
do
        echo "Doing stuff with $1"
        shift
done

That way you don't need to keep remembering which number you need to use and can gracefully deal with more than one input directory.

And always make it 'echo rm' when you're just testing, you don't want to run rm when it's not working right!

And you should quote your variables in case the filename contains spaces. "$f" instead of just $f

SYSLOGOUT(8)						      System Manager's Manual						      SYSLOGOUT(8)

NAME
syslogout - modular centralized shell logout mechanism DESCRIPTION
syslogout is a generic approach to enable centralized shell logout actions for all users of a given system in a modular and centralized way mostly aimed at avoiding work for lazy sysadmins. It has only been tested to work with the bash shell. It basically consists of the small /etc/syslogout shell script which invokes other small shell scripts having a .bash suffix which are con- tained in the /etc/syslogout.d/ directory. The system administrator can drop in any script he wants without any naming convention other than that the scripts need to have a .bash suffix to enable automagic sourcing by the /etc/syslogout script. For shell sessions, the contents of /etc/syslogout.d/" will be sourced by every user at logout if the following lines are present in his $HOME/.bash_logout: if [ -f /etc/syslogout ]; then . /etc/syslogout fi If used for X sessions it is advisable to include the former statement into the Xreset script of the X display manager instead to prevent that closing of an terminal emulator window yields unexpected results in your running X session if your X11 terminal emulator is using a login shell. Be sure then to run it under the user-id of the X session's user. See the example files in /usr/share/doc/syslogout/ for illustration. Users not wanting /etc/syslogout to be sourced for their environment can easily disable it's automatic mechanism. It can be disabled by simply creating an empty file called $HOME/.nosyslogout in the user's home directory using e.g. the touch(1) command. Any single configuration file in /etc/syslogout.d/ can simply be overridden by any user by creating a private $HOME/.syslogout.d/ directory which may contain a user's own version of any configuration file to be sourced instead of the system default. It's names have just to match exactly the system's default /etc/syslogout.d/ configuration files. Empty versions of these files contained in the $HOME/.syslo- gout.d/ directory automatically disable sourcing of the system wide version. Naturally, users can add and include their own private scripts to be automagically executed by /etc/syslogout at logout time. OPTIONS
There are no options other than those dictated by shell conventions. Anything is defined within the configuration scripts themselves. SEE ALSO
The README files and configuration examples contained in /usr/share/doc/syslogout/ and the manual page for bash(1), xdm(1x), xdm.options(5), and wdm(1x). Recommended further reading is everything related with shell programming. If you need a similar mechanism for executing code at login time check out the related package sysprofile(8) which is a very close compan- ion to syslogout. BUGS
syslogout in its current form is mainly restricted to bash(1) syntax. In fact it is actually a rather embarrassing quick and dirty hack than anything else - but it works. It serves the practical need to enable a centralized bash configuration until something better becomes available. Your constructive criticism in making this into something better" is very welcome. Before i forget to mention it: we take patches... ;-) AUTHOR
syslogout was developed by Paul Seelig <pseelig@debian.org> specifically for the Debian GNU/Linux system. Feel free to port it to and use it anywhere else under the conditions of either the GNU public license or the BSD license or both. Better yet, please help to make it into something more worthwhile than it currently is. SYSLOGOUT(8)
