  • I don't think there's an in-built option in 7-zip... Is there any specific reason you have to use 7-zip? Are alternative utilities/methods acceptable? Which version of Windows is in question?

  • In a larger scope... how is your example output any more 'machine readable', than the normal output? To me it's not any easier, as the fields don't seem delimited consistently, so the parsing/processing you'll probably have to do to the output anyway (to deal with that) could easily include skipping the first and last 'X' amount of lines... So why not just parse/process 7-zip's output (via scripting or whatever) before passing it along to the next step?

  • 7zip is ideal (but not necessary) because it works with many different types of archive formats and the list command gives just the right set of information that I need.

  • I realize I can parse the output to remove the unwanted lines, I just wanted to ask if there was a built-in way of doing this before going that route because the sum line's formatting is very similar to the regular file list lines so the regex is nontrivial.

    I wouldn't bother with Regex to remove the lines, as they will probably always be the same number/amount at top and bottom. But regardless, if your question is specifically "Can 7-zip do this?" then I'm pretty certain the answer is simply "No". If you want a solution to your actual problem, then we'll need more info so we can provide a non-7-zip solution.
