It is probably worth pointing out that the two proposals for "reverse sorting"
a wordlist:
(A) rev|sort|rev [contributed by timcanon.co.uk (Tim F O'Donoghue)]; and
(B) sort -r applied to a sorted, uniq'ed wordlist [contributed by
Martin Wynne <LNP5MWcms1.leeds.ac.uk>] differ in substance.
For example, if (A) is applied to a file that contains
ax
axa
axb
it returns
axa
axb
ax
while if (B) is applied to the same file, it returns
axb
axa
ax
The -r option for sort reverses sort's collating sequence; it has no effect on
the sequence of characters within each word.
The (A) method seems to be what the author of the awk script
[Chris Culy <cculyvaxa.weeg.uiowa.edu>] had in mind by "reverse sort," but I
would expect rev to run considerably faster than any equivalent awk script.
