From: Ben Crocker <bcrocker@xxxxxxxxxx>
SC2001: See if you can use ${variable//search/replace} instead.
SC2046: Quote this to prevent word splitting.
SC2086: Double quote to prevent globbing and word splitting.
SC2162: read without -r will mangle backslashes.
SC2181: Check exit code directly with e.g. 'if mycmd;', not indirectly with $?.
Disable:
SC2010: Don't use ls | grep. Use a glob or a for loop with a condition to allow non-alphanumeric filenames.
as any alternative is worse, i.e. harder to understand. Filenames are known
to be well-formed (i.e. no blanks or special characters) in our situation.
