to define a variable in bash, you need to have no spaces. So when you define
the timestamp variable, it looks like this (BTW, I use $(command) instead of
the backquotes in bash, mostly because I think it's easier to see):
TIMESTAMP=$(date '+%m/%d/%y_%H:%M:%S')
When you use the variable, put the "$" in front of it to expand it in the
script (again, no spaces and no plus sign):
mv /XXX/tomcat/logs/logfile /XXX/tomcat/logs/RotatedLogs/logfile.$TIMESTAMP
The problem with your original mv line is you have the wrong number of
operators for the mv command. It thinks you are trying to use TIMESTAMP
as a directory location to move to.

you may need to export the TOMCAT_HOME variable. Where are you defining it?
In your startup files or in the script somewhere? If it's in the script, it
should work just fine by using $TOMCAT_HOME, if not, export it like this at
the time it's defined:
export TOMCAT_HOME=/XXX/tomcat

There is a TON of stuff in the bash man pages. Also, some distros provide
a bash-doc package that has even more stuff.
