Is there some trick that would allow one to use bc (or some other standard utility) to return the standard deviation of an arbitrary number of numbers? For convenience, let's say that the numbers are stored in a Bash variable in the following way:

myNumbers="0.556
1.456
45.111
7.812
5.001"

So, the answer I'm looking for would be in a form such as the following:

standardDeviation="$(echo "${myNumbers}" | <insert magic here>)"
bash variables standard-deviation
