Filename to variable

[Plight]

Hi there.

I am in need of a way to check that the same file exists within two different directories using a filename as a variable.

Here is the process which requires it:

The script is reaches out (via ftp) and pulls down a file(s) and delete it afterwards. This is halfhazard because in the instance it doesnt pull down the file, yet still deletes it, we are up a creek. I am looking to pull it down to a temp location and then verify that file exists in the location in which it needs to be present to process before deleting it, adding a little extra layer for security.

The script itself is finished. If I put a file name in manually it works perfect. I just need a way to pump the filename into the variable.

Anyone know how to grab a filename and turn it into a variable?
