Thanks Omega,
I stumbled upon the backtick operator a couple of days ago but the problem that I was having was that my mysqldump is not in the same directory as my web directory.
So what I did was us the backtick operator to ls -al through to the system directory of my host and find where they kept the mysql folder.
I did, and used the above formula and it worked fine.
Thanks again for your help,
Steve.
