Print matching fields (if they exist) from two text files
Hi everyone,
Given two files (test1 and test2) with the following contents: test1: and test2:
I need to do some kind of join to obtain this result:
In short:
Join on 1st field of both files.
If a value in field #1 exists in test2, replace field #2 in test1 with field #2 in test2.
Else, leave field #2 in test1 intact.
I tried with the following join command:
but it only complies with requirement 2 above and leaves non-matching fields empty:
Any ideas will be more than welcome.
Thanks in advance.
