Much to my surprise, I seem to have found a bug in "sort."
Option "-b" turns off the inclusion of white space in a sort. However,
this also seems to be the default, and I can find no way to turn it on.
What I'm doing is sorting amateur radio call signs. They have the
format:
(prefix) (number) (suffix)
The prefix can be one or two letters, and the field normally sorted by
is the suffix.
The data I'm trying to sort is organized as such:
N9TLS
KG9LX
N4FOZ
KB9PRR
(TLS, LX, FOZ, and PRR are to be sorted in the example.)
I need to sort by the fourth character, including white space, but
"sort" (with only "+4" or "-k 4" option) ignores the spaces or, if
substituted, punctuation marks.
