Re: join bug?

[german rigau]

Hello again,

Thanks a lot for you quick reply ...

But, BOTH files were sorted previously with default options.

address@hidden BaseConcepts]$ cat kk1
ice_cream%1:13:00::
life_style%1:07:00::
part-time%3:00:00::

address@hidden BaseConcepts]$ cat kk2
ice_cream%1:13:00:: 07510835 1 1
icecream%1:13:00:: 07510835 1 0
life_style%1:07:00:: 04875322 1 2
part-time%3:00:00:: 01131371 1 21

address@hidden BaseConcepts]$ join <(sort kk1) <(sort kk2)
life_style%1:07:00:: 04875322 1 2
part-time%3:00:00:: 01131371 1 21

address@hidden BaseConcepts]$ join -v 1 <(sort kk1) <(sort kk2)
ice_cream%1:13:00::

Then, the problem is on the "sort" command because:

address@hidden BaseConcepts]$ more kk2
ice_cream%1:13:00:: 07510835 1 1
icecream%1:13:00:: 07510835 1 0
life_style%1:07:00:: 04875322 1 2
part-time%3:00:00:: 01131371 1 21
address@hidden BaseConcepts]$ sort kk2
icecream%1:13:00:: 07510835 1 0
ice_cream%1:13:00:: 07510835 1 1
life_style%1:07:00:: 04875322 1 2
part-time%3:00:00:: 01131371 1 21

In fact, adding icecream%1:13:00: in kk1 we obtain:

address@hidden BaseConcepts]$ sort kk1
ice_cream%1:13:00::
icecream%1:13:00::
life_style%1:07:00::
part-time%3:00:00::
address@hidden BaseConcepts]$ sort kk2
icecream%1:13:00:: 07510835 1 0
ice_cream%1:13:00:: 07510835 1 1
life_style%1:07:00:: 04875322 1 2
part-time%3:00:00:: 01131371 1 21

Which could be the reason to produce two different orderings??

Thanks in advance,

German
