in reply to problem sorting by non-consecutive fields
This is a Perl site, not man sort.
- Sorting data that don't fit in memory
- Schwartzian Transform
- Advanced Sorting - GRT - Guttman Rosler Transform
- Complex sorting
If that doesn't help, try File::Sort or the Perl Power Tools version of sort. Either way, you'll probably need to read the manpage for sort and try it for yourself. I had the same problem figuring sort key definitions the other day - it took a few minutes tinkering before I understood it - you should try too.
If the information in this post is inaccurate, or just plain wrong, don't just downvote - please post explaining what's wrong.
That way everyone learns.
