[MacPerl-Forum] testing for file existence, listing files in specific dir, OS9

[Philip MacMenamin]

Hi, 

I have a script which I wrote on my linux machine, but has to run on MacOS9s. 
In this script I need to test to see if files exist: 
if (-e $myFileName)

and I need to copy or move files around with in this directory. 
`mv $oldFileName $newName`;

How do I go about this in MacPerl?

Thanks, 
Philip.
