SC2212

Use 'false' instead of empty [/[[ conditionals.

Problematic code:

if [ ]
then
  echo "Temporarily disabled"
fi

Correct code:

if false
then
  echo "Temporarily disabled"
fi

Rationale:

[ ] is a somewhat obscure way of expressing falsehood, and the behavior is likely intended to allow the incorrectly quoted command [ $var ] to still work when the variable is unset.

POSIX has a more descriptive command false for this.

Exceptions:

None. This is a stylistic suggestion, and has no effect on how the script works.
