Comment(by drkirkby):
I've not checked in detail, but assuming the 32-bit numbers are randomly
distributed for all files, the probability of an undetected error is less
than 2.4 x 10^-10. My assumption about 'randomly distributed' may be
incorrect - a job for you mathematicians if you are so motivated! But
'cksum' was designed for this specific use. POSIX says even deliberate
deception is difficult, though probably not impossible.
Having looked at the POSIX spec, I agree the use of a tab rather than a
space is a violation, and so should be reportedto Oracle, who bought Sun.
I'll do that, though it is low on my list of priorities. The combination
of 'cksum' with 'awk' seems good to me.
