Usage: nomad job revert [options] <job> <version>

Revert is used to revert a job to a prior version of the job. The available

versions to revert to can be found using "nomad job history" command.

Revert Options:

-detach

Return immediately instead of entering monitor mode. After job revert,

the evaluation ID will be printed to the screen, which can be used to

examine the evaluation using the eval-status command.
