  The script I use to upload a new version of XML::Twig to my site:

  #!/usr/bin/perl
  use XML::Twig;
  
  my $MIRROR_DIR = "/web/mirror/infotree/xmltwig";
  my $WEB_DIR    = "mirlin:/web/infotree/";
  
  my $version  = $XML::Twig::VERSION; # can't get this from the shell!
  my $tar      = "XML-Twig-$version.tar.gz";
  my $dev_text = "twig_dev.txt";
  my $dev_html = "twig_dev.html";
  my $readme   = "XML-Twig-$version.README";
  
  system "make clean; rm Twig.pm; perl speedup Twig.pm.slow > Twig.pm;

  Like you, I do my calculations from the shell using Perl, but I at least turned the "perl -le 'print...'" into a shell alias to make it easier to type ;)

      I've known about bc before, but somehow I can't wrap my head around it... I know, it's probably due to my stupidity as I can't say it looks that difficult.

      Maybe I'm not good at simple things, maybe that's why I now work where I do.

      Hmmmmmm...

  My calculator is perl -de 1. Earlier this semester I had a bit of a disaster in software engineering class as I was sitting on the front row doing COCOMO calculations for the class and coming up with the wrong answer because I didn't understand the use of Perl's ** operator. :)

  Occassionlly I use shell scripts for build processes. Usually they grow into a perl thing though. Always using a system() wrapper that dies nicely on errors.
  
  For calculations I use "bc". The 3 second bc guide will instruct you to use
  
  scale=10
  
  as your first command.
  
  I also use awk '{print $1}' once in a while instead of "perl ... (split)[0]". Why? No clue. :-) The fingers are doing it.

  I've been using dc for years. It got to the point where I had an xterm alias in my WindowMaker menu for dc that I used constantly.

  Unfortunately, I don't have a three-key shortcut to bring up dc on OS X yet...
