Public bug reported:
In the following examples, I expect /usr/bin/sort to always put '.'
(0x2E) before 'a' (0x61)
$ echo -e 'ab\naa\n.a' |sort
.a
aa
ab
$ echo -e 'aba\naaa\n.aa' |sort
.aa
aaa
aba
$ echo -e 'abb\naaa\n.ab' |sort
aaa
.ab
abb
The difference between examples 2 and 3 is the third byte of each line
is one bit higher, and for some reason this makes the first byte "."
simultaneously after "a" and before "a" in sort order. That's should be
contradictory, and this is repeatable.
This also happens when other punctuation marks are the first byte (remember 'a'
is 0x61)
$ echo -e 'abb\naaa\n!ab' |sort # ! = 0x21
$ echo -e 'abb\naaa\n_ab' |sort # _ = 0x5F
$ echo -e 'abb\naaa\n{ab' |sort # { = 0x7B , so not only for bytes that are <
0x61
