[ale] changing dash to bash in ubuntu

[Michael Potter]

I had never heard of dash until this thread.
I did a little googling and it appears that dash does not support 'set
-o pipefail'.
That alone is a deal killer for me.

I have read that who are concerned about the overhead of bash should
consider pdksh.  pdksh support pipefail.
