Question File Existence Question (Urgent)

G'day all

Just wondering if anyone can help me, is it possible, within a Bourne Shell script, to check if a entered file exists? Smilie

An example would be (And this is the reason why I'm asking) If I was to write a super-basic backup script, and the user entered a filename, what sort of code would be suitable to check whether or not the file is actually there.

Thankyou all for your help

Cheers and Beers (If your old enough)
