Check These Out
Lists out all classes used in all *.html files in the currect directory. usefull for checking if you have left out any style definitions, or accidentally given a different name than you intended. ( I have an ugly habit of accidentally substituting camelCase instead of using under_scores: i would name soemthing counterBox instead of counter_box)
WARNING: assumes you give classnames in between double quotes, and that you apply only one class per element.

Enhanced version: fixes sorting by human readable numbers, and filters out non MB or GB entries that have a G or an M in their name.
example:
--------------------------------------------------------------------------------------------
user@ubuntu:~/workspace/SVN/haystak-repos/trunk/internal/src$ addpi
--------------------------------------------------------------------------------------------
Now that directory is in the list of fast access directories.
You can switch to it anytime like this:
--------------------------------------------------------------------------------------------
user@ubuntu:~$ pi internal`
user@ubuntu:~/workspace/SVN/haystak-repos/trunk/internal/src$ --------------------------------------------------------------------------------------------
Please note the backquote ( the symbol that shares its key with ~ in the keyboard )
pi will switch you to that directory.
To see the list of all fast access directories you have to say "cat ~/.pi"
