Hi Guys,
I know how to use the sort, -k to sort two files, but face the problem where need to sort differient fields in differient files.
FileA:
20090610 23:58:59 444
20090610 23:52:13 555
20090611 00:00:02 6
FileB:
1 63660 5807 Wed 10/06/2009 23:54:58
4 63660 5807 Wed 10/06/2009 23:59:58
33 63660 5807 Wed 11/06/2009 23:54:58
###################
So For FileA, field1 and field2 sort date, and for FileB, sort date by field date. As we can see fileA and B date are in differient fields, how to sort these two files?
Thanks
