Question on script using awk

2131100 COVS/100C E|FWP AREAS|MIDWEST|
2131100 COVS/100C E|FWP AREAS|CONSTRUCTION|
2131100 COVS/100C E|FWP AREAS|FTC|
2131100 COVS/100C E|FWP AREAS|FWP AREAS|
2131100 COVS/100C E|FWP AREAS|CLEANING|
2131100 COVS/100C E|FWP AREAS|FCRE|
2131200 COVS/100C UPS|UPS ROOMS|CONSTRUCTION|
2131200 COVS/100C UPS|UPS ROOMS|UPS ROOMS|
2131200 COVS/100C UPS|UPS ROOMS|FCRE|
2131200 COVS/100C UPS|UPS ROOMS|EMERGENCY|

I am running a report that produces the output shown above. I am trying to use awk in the script to format the output to look like this

2131100 COVS/100C E|FWP AREAS|MIDWEST|CONSTRUCTION|FTC|FWP AREAS|CLEANING|FCRE|

All information would be on one line but the carriage return was forced when typing into the area for this post.
Basically, I want to keep only the first occurence of the information in colums 1 and 2. I then want to list the information in column 3 from left to right in the same row. I want to do this for each new number listed, ie: one row that looks like the example above for 2131100 another row for 2131200 etc...

Attached below is a copy of the AWK script which does not seem to be working properly.

Any insight on how to accomplish this would be greatly appreciated.

awk -F"|" 'BEGIN {SS_A=""}
{if (NR==1)
{SS_A=$1; printf $0}
else
{if (SS_A==$1)
{printf "|"$2}
else
{SS_A=$1;
printf "\n"$0}
}
} END {printf "\n"}' $SF_OUT

The following works for me:

Code:

#!/usr/bin/awk -f

BEGIN {
  FS="|"
  line=""
}

$1 $2 == line {
  printf $3 FS
  next
}

{
  if (line != "")
    print ""
  printf $0
  line=$1 $2
}

END {
  print ""
}

reply to awk code

thank you for the response. Any idea why the script suggested would be producing output that contains 2 occurences of the 2nd field?

Any thoughts are welcome. Also, if an example of input and/or output would be helpful I can provide them.

Thank you.

Please do provide an example of the input you used that caused a problem, as well as the output you saw. The output I get from the example input you posted originally is:
