Interesting.
I never got round to deleting info. I'm sure many do.
I have LFS-5.0 in everyday use. I'm backward, but not that far back.

Generally, scripting questions fit better on lfs-chat, and you are
more likely to get good answers there.
I don't do chat, largely because I talk too much.
I may join if I can make any headway with the file. But everything has
to be described in posix regexes, which are not as handy as perl imho
If I can't describe the sections in posix REs, I can't bring awk or sed
to bear on it. I want to split each line at one very awkward point.
Most of us find perl is a lot harder than awk or sed, but yes the
regexes can be "simpler". How about using some perl from the shell to
write the regexes, along the lines of
cat $1 | perl -p \
-e 's/-your-regexp-here-/-and-here-/g;'
-e 's/another-regexp/and-output/g;'
and pipe the output to awk to format it.
Or, create a little test data (in the form you expect to come out of
the regexes), hack up some awk to print it, then try a2p on the awk to
get it into perl if you are happier with that. Break the problem down
into manageable chunks. Use the tools you are most comfortable with.
