I would like a small bash script which will allow me to backup in to a tar.gz file all the files on a system modified after 14 January with exception of the files in /opt and /home/web.  Thanks in advance, Nicholas waltham

Hmm, something like
(find / -mtime 2 -print|grep -E -v ("/opt"\|"/home/web"))|gzip >backup.tar.gz

might work.

Thanks - I didn-t type that in, but I guess it needs a call to the tar program too....

#  generate the list of the files to be backed up
touch -t 01140000 /tmp/today
find / -newer /tmp/today | egrep -v "/opt|/home/web" >/tmp/filelist
rm -f /tmp/today

# if your tar supports -L option (read files to be tared from a file)
tar -cvf - -L /tmp/filelist | gzip >tar0114.tar.gz

# if your tar doesn't support reading file list you can try
tar cvf - $(cat /tmp/filelist) | gzip >tar0114.tar.gz
# but if the filelist is greater than command line max size you will receive an error

# you could obviously use cpio instead
cpio -o </tmp/filelist | gzip >cpio0114.cpio.gz

# in many cases you can pipe the list command generator with tar or cpio command
# without saving the list to a file
rm -f /tmp/filelist

Whops, forgot the tar part :)
(find / -mtime 2 -print|grep -E -v ("/opt"\|"/home/web")|tar cf -)|gzip >backup.tar.gz

This should work...
