How to cd in shell scripting?

Hi guys,

Can anyone help me please, I have a code which will retain number of files maximum of 3 and will remove the one on top (using head -1 command). See code below:

Code:

#!/usr/bin/sh

num_of_files=`ls /home/user/USER_LOGS/ | grep UserActivity | grep UMB00 | wc -l`

if [ $num_of_files -gt 3 ]
then
remove=`ls -lrt /home/user/USER_LOGS/ | grep UserActivity | grep UMB00 | head -1 | awk '{print $8}' | rm \`xargs\``
$remove
fi

The code is located on the same directory /home/nsadm/USER_LOGS/. It functions well trying to give the output that I want, however when I already went out of the sub-directory USER_LOGS hitting the command cd which by default will bring me to /home/nsadm/, then I tried to run the script as /home/nsadm/USER_LOGS/remover.sh, the script didn't work.

I hope anyone can suggest what to do because I'm planning to place this script in CRON. By the way, I've also tried to run the script as root user because only root user can deploy entries in CRON, so as per login default directory is /root (for root user), then I ran the script /home/nsadm/USER_LOGS/remover.sh, again it didn't work.

Here's the error that I've got:

Code:

rm: cannot remove `UMB00_UserActivity_20120103_094606.log': No such file or directory
