    This is in the right direction, but would be much better if it showed at least a minimal working example from the question. Commented Jul 27, 2017 at 10:21
  • I tried it with the code I saw from the example but still, the PO numbers are aligned in the left side of the screen. (printf "ISA GS Trans Sender_ID Receiver_ID INV_PO_NUMBER ASN_PO_NUMBER\n${isa} ${gs} ${trans} ${sender} ${receiver} ${bigponumber} ${asnponumber}\n") | column -t Commented Jul 28, 2017 at 5:26
  • I think the problem is with empty var which do not fill the column, you should ether try to fill blank with other characters or try with a different separator using the -s option Commented Jul 28, 2017 at 8:17
  • Take a look at the command in bigponumber & asnponumber zgrep -oP 'BIG.[\w\s\d-]*.[\w\s\d]*.[\w\s\d]*.\K[\w\s\d-]*' < $LINE | sort -u. It outputs all the data gathered from the content of $LINE(text.file). Most of the time it has more than a hundred output. That I see is the problem because every output of data prints in default position which is in the left side of the screen. Commented Jul 28, 2017 at 9:07
