Synopsis
condor_off [-help -version]
condor_off[-graceful -fast -peaceful] [-debug] [-pool centralmanagerhostname[:portnumber]] [-name hostnamehostname-addr
"<a.b.c.d:port>""<a.b.c.d:port>"-constraint expression-all] [-daemon daemonname]
Description
condor_offshuts down a set of the Condor daemons running on a set of one or more machines. It does this cleanly so that checkpointable jobs
may gracefully exit with minimal loss of work.
The command condor_offwithout any arguments will shut down all daemons except condor_master. The condor_mastercan then handle both local
and remote requests to restart the other Condor daemons if need be. To restart Condor running on a machine, see the condor_oncommand.
With the -daemon masteroption, condor_offwill shut down all daemons including the condor_master. Specification using the -daemonoption will
shut down only the specified daemon.
For security purposes (authentication and authorization), this command requires an administrator's level of access. See section 3.6.1on
page for further explanation.

% condor_off cinnamon cloves vanilla -daemon collector
