Second Edition, Page 89, Chapter 5 -- typo

[clevengr]

The last paragraph on page on page 89 says "We use source ~/.bash_profile in line 4... ". However, that line is actually line 3 in the preceding listing.

It should actually be line 8 now (the 2nd task in the group), but you are correct! I've updated this in the manuscript and will hopefully have a book update out soon.
