Thanks for being that open. Usually students' home- and coursework questions need to be posted in the in this forum under special homework rules. A thesis in a non-IT field I think is a border line case. Did you consider awk to check for NF (number of fields) equals 4 (save $1 then) or less than 4 (add saved $1 to begin-of-line then)?

There's text books on awk, and / or the man page. Look into these fora and try to understand the problems and track the solutions proposed. Start creating your own solutions to simple up to more complex problems.
