Of these, cksum does *not* state that it "shall conform to the Base
Definitions volume of IEEE Std 1003.1-2001, Section 12.2, Utility Syntax
Guidelines." (all the others do). Just for the record, Microsoft's
Services for Unix 3.5 and OpenBSD 3.1 behave like this:

                   SFU               OpenBSD
bc -              name             name
cksum -          name             name
expand -         name             name
file -           stdin            stdin
fold -           name             name
grep foo -     name              stdin
head -          name              name
nl -             stdin            n/a
od -             name              name
sep p -         name              name
wc -             name              name

(and for me, GNU file - is stdin)
