An all shell approach would be:
Code:
{ 
  read; read
  while IFS="|" read dep rev
  do
    printf "%s\n" "$dep"
  done
} < infile

Unless you have other things that have to be done by something other than awk between your calls to awk, it would be much more efficient to do all of the work in a single awk script rather than calling awk n-1 times (where n is the number of lines in your input file).
