I am trying to join 2 large files(1 file is 699M and other is 20GB). Both the files have only 2 columns. The command I am using is:
join -1 2 -2 1 -t , -o 1.2,0,2.2 file1 file2. When I try the command using a smaller
file1, the command works fine. I tried printing
$? to see if the exit code is non zero, but it is not.
How can I debug to find out the reason?
Some info: O.S: RHEL5 Arch: x86_64
