not to belabour the obvious, but the above only gives
a quick fingerprint of which files _may_ be identical.
cmp(1) is the arbitrator of true identicalness.
that is, _I_ would never ever delete files deemed
“identical” only by a fingerprint (checksum) without
also doing a `cmp' to confirm. (and even then,
there is an issue of files which have identical
contents, but are not actually the “same” file.
let's not go there .... ;-) )
p.s. I concur with Colm's suggestion to use a decent
versioning system (which excludes CVS, IMHO) to
avoid some instances of this problem.
