I don't use csh, but you can probably do it with a single invocation of 
'find'.  Something like

	/usr/bin/find /dir/to/look -maxdepth 1 -name name.of.file \
		-size +1c -exec /usr/bin/ls -l {} \;

This example runs "/usr/bin/ls -l" on the file, if it exists in the 
directory and is 1 byte (or more) in size.

If you really want a csh script it will probably go something like:

	#! /bin/csh
	if ( -f /usr/filename.txt && ! -z /usr/filename.txt ) then
		. . .
	endif

but I'd really suggest you confer with the csh man-page and TEST that 
little fragment before you rely on it for anything, because as I said, I 
don't use csh.
