Hi Scrutinizer.

Thank you for the code suggestion. I tried your code above with the input_file.txt attached but I didn't get any data in the output file.

This is what I executed:

Code:
awk -v search_col_pos=33 -v search_str_len=2 -v segment_type="UF" '
  function cond_print(record) { 
    if (substr(record, search_col_pos, search_str_len) ~ segment_type) print record
  }
  !/^[0-9]{25}/ {
    prev=prev RS $0
    next
  }
  {
    if(NR>1) cond_print(prev);
    prev=$0
  } 
  END {
    cond_print(prev)
  }
' input_file.txt > output_file.txt

Can you please help?

Hi, your previous sample contains "UF" at position 29, not at 33 . And this sample does not contain "UF" at all.
