checksum than the 9.x cksum command?

Updated: 04/05/01 The 9.x cksum was defective – it did not correctly implement the POSIX spec. That is understandable, because the POSIX cksum spec does not supply a test suite to easily verify an implementation is correct. The 10.x/11.x cksum is correct. Unfortunately that means it can not match 9.x cksum. Another implementation that did not match POSIX spec was in AIX 3.*; I haven’t checked AIX 4.* or Solaris. Other good implementations (they give the same answer as 10.x/11.x cksum): – GNU cksum – Solaris 7/8 – HP Software Distributor swpackage program, on both 9.x and 10.
