JavaScript

Linky

Well, this is lame.

      javascript:alert('<a href="'+location.href+'">'+document.title+'</a>');
      

Ubuntu Shell Script

up.sh

A script that runs aptitude to update installed packages.

      #!/bin/sh

      # Returns just the user ID number from the id command.
      getUID() {
          id $1 | sed -e 's/(.*$//' -e 's/^uid=//'
      }

      if [ "`getUID`" -gt 100 ]; then
        echo "ERROR: Insufficient privileges. Use sudo."
        exit 1
      fi

      echo "(BEGIN UPDATE)"

      aptitude update

      echo "(UPDATE DONE)"
      sleep 3
      echo "(BEGIN UPGRADE)"

      aptitude safe-upgrade

      echo "(UPGRADE DONE)"
      exit 0
      

Obviously there is not much code on this page. I have tended to post code on my blog at BlueCog.com instead of here.
