  set -u

Another great thing I could have read in the effin manual.

He could have added a little reminder about the ${VAR:-default} syntax. [[ http://www.ooblick.com/text/sh/ search for Quasi-variable constructs ]]

Great read, thanks.

Or look at the manpage

       ${parameter:-word}
              Use  Default  Values.  If parameter is unset or null, the expan-
              sion of word is substituted.  Otherwise, the value of  parameter
              is substituted.

Agreed, I was just sayin for the sake of the article, he brings up the subject of unitialized variables, without mentioning this other way.
