1. Schwartzian Transform

   • Well-known to Unix shell programmers:

         # Sort file names by file size

         ls -l | sort -n +4 | awk '{print $NF}'

         # Sort output of SOMETHING from most frequent to least

         SOMETHING | uniq -c 
           | sort -nr | awk '{$1=""; print}'

• I first gave this talk at Perl Conference 2 in 1998

• At last, I have an audience that will appreciate this slide
