I notice sha256sum does not correctly parse a file with a PGP header. Here is a script log:

There is a spurious extra space at the start of filenames in the larger file.
If I just extract the hash lines it works:


toby@toby-pc:/tmp/test$ egrep zip\|bz2 hashes.txt > hashes1.txt

toby@toby-pc:/tmp/test$ sha256sum -c hashes1.txt
