Since I have all of my lab machines update their OS automatically from
a cron job, I'm wondering if it's possible to do the same with public
domain software? Is there some software which I can obtain to enable
this? I could do it with wget or curl but most of the time, I cannot
think of a way to detect if the software is a new release. Does
anyone do this from the shell? Thanks for any thoughts.
