  • when cutting-n-pasting your awk script into my environment I'm getting syntax errors; please verify your code and update the question accordingly Commented Jan 15 at 17:06
  • So you would like to extract CN=whatever.com,O=XYZ,L=Toronto,ST=Ontario,C=CA and whatever.com from the subject line? Is that it? Commented Jan 15 at 17:08
  • instead of using field numbers to describe which data you wish to display, reference the actual strings from the input; we can't tell if your understanding of field numbers is the same as our understanding of field numbers; also, have you verified RSTART contains what you think it does? also, please clearly state which of your output lines is the expected/desired result Commented Jan 15 at 17:09

    Do you absolutely need the BEGIN {F=" "; FS = "\n"; RS = ""; OFS = "\n"} configuration for purposes not shown here, or is this the complete problem statement? Commented Jan 15 at 17:21

    Regarding "would it be possible if line 18 contains..." - are you looking for a script that does something with the 18th input line or the line that starts with subject-alternative-name which just happens to be line 18 in your example, or the line following the line that starts with subject "CN..." or something else? Actually - same for "line 17" vs "staring with subject". Please edit your question to clarify how you want the lines target to be identified. Commented Jan 18 at 14:04
