Shell Programming and Scripting

Hi all

I need specific fields from a file to be tabulated into a single file.
I have a file with the following :-

FIELD1 InfoA FIELD2 InfoB
FILED3 InfoC

FIELD1 InfoD FIELD2 InfoE
FIELD3 InfoF

The output I would like is as follows :-
InfoA|InfoB|InfoC
InfoD|InfoE|InfoF

Any ideas. I have though of using grep and cut to create a file for each field and then use sed to read each line and echo it into a single line, however have not been able to.

Thx

J

file:

Code:

FIELD1 InfoA FIELD2 InfoB
FILED3 InfoC

FIELD1 InfoD FIELD2 InfoE
FIELD3 InfoF

result:

Code:

InfoA InfoB InfoC
InfoD InfoE InfoF

Code:

awk ' {
        if(NR % 3 == 0) {continue}        
        if(NF > 2) 
        {
                    printf("%s %s ", $2, $4)
                    continue
        }
        printf("%s\n", $2)        
      } ' filename

Jim's code appeared to be correct, so I condensed it:

Code:

4==NF { printf "%s|%s|", $2, $4 }
2==NF { print $2 }
