[one-users] examples of "pre", "post" and "clean" scripts for VNM

[José Valerio]

Hello,

I would like to see some examples of the "pre", "post" and "clean" 
scripts that one can make on VNM, I saw for example the scripts on 
/var/lib/one/remotes/vnm/ebtables and they are ruby scripts...

let's say for example that I want to execute some shell commands before 
deploying my VM, how could write this on the "pre" script?

I'm using OpenNebula 3.4

thanks in advance
