Convert rows to columns using AWK
Hi , I am struck while coding AWK script. Need your help to convert rows into columns. I should copy only those rows which are marked to Y in a file and ignore N rows. Please help me find a solution.

input file

Code:
1|abc|Y
2|cdf|Y
3|efg|N
4|xyz|Y

my output should be something like this

Code:
abc|cdf|xyz

Thanks in advance
Rashmi

Code:
awk -F\| 'END {
  print r
  }
$NF == "Y" {
  r = r ? r FS $2 : $2
  }' infile

Or using less memory, but with an extra trailing FS:

Code:
awk -F\| 'END {
  print x
  }
$NF == "Y" {
  printf "%s", $2 FS
  }' infile
