send output to /dev/null when trying to glean version
Merge branch 'devel' of esgf.org:esgf-security into devel
    Bug fix: Was sending the version number directly instead of the version command

    The key issue is that I was sending the version value version directly so the eval of the version string gives
    " <version value> command not found"
    The thing is that this value does not evalate and the current version is empty.
