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)

Check the manual pages for your shell (look for "if" statements), the "test" command, and integrate them...

For example:

if [ -n "$var" ]; then
echo Blap
else
echo Bloop
fi
