Invoking rsync from a script with null parameters
I'm working on a bash backup script using rsync.
(kubuntu precise 12.04, rsync 3.0.9-1ubuntu1)
To avoid having a number of slightly different rsync commands, I would
like to use shell variables as part of the rsync command. I.e.:
DRYRUN="-n"
rsync "${DRYRUN}" more parameters ...
This does not work if DRYRUN="" - apparently because this command becomes
rsync
