Public bug reported:
The --reverse option is supposed to reverse the sense of comparisons, but does
not affect numeric ('g' or 'n') sorts.
With the input filed 02 q
l 10 f
abc 01 x
abc 01 y
abc 01 z
n 10 u
d 02 m
d 02 b
b 10 c
I get the same results with either of
sort --reverse -k2n
sort -k2n
namely
abc 01 x
abc 01 y
abc 01 z
d 02 b
d 02 m
d 02 q
b 10 c
l 10 f
n 10 u
But if I do
sort --reverse -k2
I get
n 10 u
l 10 f
b 10 c
d 02 q
d 02 m
d 02 b
abc 01 z
abc 01 y
abc 01 x
And the same things happen with or without leading zeroes on field 2.
