Off-topic: what's the point of the extra $(..) here? I haven't seen this
construct before together with the '<' operator, but then again I've long
since accepted that I'll never understand all of bash (or equivalent).
It is a way to substitute the result of something executing in a
subshell. an alternative to backticks
echo $(ls)
is equivalent to
echo `ls`
