Please fix the third command,
$ echo -e 'a1\nb2\nc3\nb2'|sort -n|sort -u
a1
b2
c3
$ echo -e 'a1\nb2\nc3\nb2'|sort -u|sort -n
a1
b2
c3
$ echo -e 'a1\nb2\nc3\nb2'|sort -nu
a1
or warn right there on the man page.
Sure, you say
-u, --unique
with -c, check for strict ordering; without -c, output
only the first of an equal run
but still warn that the above will happen if one tries to combine
anything with -u.
