routes: replace sh to bash

/bin/sh in most systems will be a symbolic link to others shell.
Usually this link points to /bin/bash and in some distro they point to another
shell. For instance Ubuntu links sh to dash and so on.

With this patch we avoid compability problems that we might have in
distros that sh does not link to bash.
