I have two files:
s2.txt
14 3KC12828ACBA
43 8DG59242BAAD
25 8DG60566AAAF
6 8DG60912AAAF
and pbas.txt:
3AG33662AAAC
3KC12828ACBA
8DG59242BAAD
8DG60349AAAC
8DG60565AAAG
8DG60566AAAF
8DG60568AAAC
8DG60912AAAF
8DG62635AAAC
Using bash on UNIX I want to join files in order to obtain one file like that:
3AG33662AAAC
3KC12828ACBA 14
8DG59242BAAD 43
8DG60349AAAC
8DG60565AAAG
8DG60566AAAF 25
8DG60568AAAC
8DG60912AAAF 6
8DG62635AAAC
How can make that?

That's what
join
does:The options say:
-2 2
: the second file uses the second column to store the key-a 1
: output all lines from file 1, even if there's no match in file 2.
