Is my disk too crowded ?

[Charles Blair <c-blair@illinois.edu>]

   I have been recently noticing that the find
command is taking a long time, and my /usr (see df
output below) is 73% full.  Should I do something?

   libreoffice seems to be using a lot of space, and
I only use it to read .doc files other people send me.
I don't use the spreadsheet or database features.
Is some reduced-functionality version available?
