-z $filename checks whether the string contained in the variable $filename is of length zero or not.
If you understand string functions in c/c++, -z $filename is the same is as the function if (strlen(filename) == 0) To check whether the file has a size greater than 0, use the construct Code:
[ -s "$filename" ]
