Any of your options tried does what you want them to do, so I guess your file has some "hidden" features like e.g. non-printing control characters. Try
Code:
od -tx1c temp.hash.txt

and post the result.

The default limit is 3. if 0 (zero) is specified, the result have many continuous blank lines. file The SGML source file, named either file or file.sgml FILES
