[one-users] bash scripts

[Javier Fontan]

I've been checking the distros supported (and some others that are not
supported) have bash4. It is probably not needed to maintain
compatibility with older bash versions. Can you be more specific on
the advantages the new features in bash 4 will have for the scripts?

I also would want to know more about the quirkiness in our bash
scripts to fix that and maybe create a standards document so all the
scripts use the same constructs.
