I think this answer the need, but using this to populate a variable implie
anyway a fork.
realPathArray=$(realpath /bin/sh /usr/bin/X)
It would be nice if builtins intended to produce *answer* use more or less
common switch like `printf -v` behaviour.
usage: realpath [-a array] [-csv] pathname [pathname...]
options: -a NAME assign the output to shell array NAME rather than
display it on the standard output
-c check whether or not each resolved path exists
-s no output, exit status determines whether path is valid
-v produce verbose output
