From: Ben Crocker <[email protected]>

SC2006: Use $(...) notation instead of legacy backticked `...`.
SC2013: To read lines rather than words, pipe/redirect to a 'while read' loop.
SC2086: Double quote to prevent globbing and word splitting.
SC2166: Prefer [ p ] && [ q ] as [ p -a q ] is not well defined.
EVEN BETTER: use [[ p || q ]]
