realpaths
Prints aboslute paths of existing files.
ABOUT
Print absolute paths of files. All paths that exist are printed.
(ie, noting softlinks and mount points can be need revealing).
realpaths(1) is a realpath(3) clone and was made due to
some realpath bugs.
unlike realpath(3), realpaths(1) does not bake or guess part of
the path: it only uses info from Linux and or libc from the
filesystem of real files. It runs about same speed though.
It's important when dealing with symlinks and mounts to use
real information...
