Modern versions of awk have a sort command. I'm not sure if it was included even in the original awk.

well. i see now, that perl is a best solution than bash. after all perl was made to process text right? :P
and perl has always been in my todo-list
the problem there would be to pipe the info to dzen
because the way dzen works, i need an never ending loop, so dzen dosnt die
is posible to do that piping from a perl script?
Certainly, but I'm not really suggesting you move to Perl just for this. There are really two schools of thought on this; skip awk, and only learn Perl; or move to Perl if you run into situations which awk cannot handle comfortably. If you need to process binary data or very large data sets, Perl was designed to overcome the limitations awk have in those areas.
But the requirements you have shown so far should be easy to handle in awk; it's just not clear from reading the code in which direction you want the script to grow, and/or I was too lazy to rewrite it all.
