one of the real benefits with cfengine is the methodology requires. You
are required to implement changes, rather than just executing them. It
leaves a trace of your work and what is actually done. So even if you
have a single script that need to be run once it makes sense to use
your cfengine configuration for this. If you still want to do this
at a specific time or with ssh, you do something like this:

import:
  remote_manual::
    cf.tasks

cf.tasks

copy:
  /some/masterfile1
    dest=/path/to/script1
    server=$(policyhost)
    type=checksum

  /some/masterfile2
    dest=/path/to/script1
    server=$(policyhost)
    type=checksum

shellcommands::
  Yr2003.July.Day10.Hr13.remote_manual::
    "/path/to/script1" ...

  Yr2003.July.Day10.Hr10.remote_manual::
    "/path/to/script2" ...

  Yr2003.June.Day15.Hr16.remote_manual::
    "/path/to/script1" ...

Mark might tell you to use cfservd on each host and run cfrun, but that
might not work for you, and you'll do this with ssh and call cfagent
(maybe with sudo from a non-privileged user on the remote side).

ssh -t remotehost "/usr/sbin/cfagent -Dremote_manual -K -q -v"
