Considering the sort key: a, a01 and a02, if there s no trailing fields, the sort result looks like:
$ cat test1
a01
a
a02
$ sort test1
a
a01
a02
$
But if there are tailing fields, something goes strange:
$ cat test2
a01 7
a 12
a02 42
$ sort test2
a01 7
a02 42
a 12
$
为什么关键“a”从这种结果的顶端到底?
My sort version is "sort (GNU coreutils) 5.97".
我的网页sort 说:
*** WARNING *** The locale specified by the environment affects sort order.
Set LC_ALL=C to get the traditional sort order that uses native byte values.
And indeed, if I set LC_ALL=C and run sort on your second example, I get:
$ LC_ALL=C sort < tosort
a 12
a01 7
a02 42
Your default locate is probably something other than C.
