bash or zsh?

[k8hertweck]

zsh is apparently superior, and Mac OS X now ships with zsh as default. However, bash is still default on most clusters.

Easiest option is to teach things that will be consistent between these two most common shells (ideas from Dirk):

• double square brackets
• $() instead of back ticks to access sub shell

Need to test materials on zsh and see where differences are, and how to accommodate (include explanation of differences, or ask everyone to use bash?)

• command prompt
• include links above
• for loop recall
