At this point, if you want to avoid using shell you have only option
which is to use posix.fork() and posix.exec() which is too verbose and
not optional (as Florian Weimer says, posix_spawn() can be implemented
more efficiently than usual fork() / execve() sequence).
Typical use-case is shown below.
-- Before
pid = posix.fork()
if pid == 0 then
assert(posix.exec("/foo/bar"))
elseif pid > 0 then
posix.wait(pid)
end
-- After
assert(posix.spawn("/foo/bar"))
