Hi,
here is a problem I'm working on. It's not PERL-specific, rather it is a
problem in sorting followed by grouping.
Suppose I have a set of lines that have tab-delimited text, thus:
1 w 3 wer
2 a 4 rte
4 w 2 weg
6 d 4 fhg
5 d 7 dfl
6 w 4 ald
8 a 3 dsl

I would like to first sort the lines based on the 2nd token (w,a, w, d, etc)
and then group the lines based on the 2nd token.

At the end of this sorting/grouping I should have the lines grouped thus:
2 a 4 rte
8 a 3 dsl

6 d 4 fhg
5 d 7 dfl

Does anyone know what happened to this website: http://web.archive.org/web/20041123005900/http://www.raycosoft.com/rayco/support/perl_tutor...
It says its not available. I thought it was a great reference and explained the diffs between map and grep and even sort.
Does anyone have a softcopy of its data that you can send me?

thank you!
