Usage: nomad action [options] <action>

  Perform a predefined command inside the environment of a given context.
  Currently this acts as a wrapper around the job action command.

  When ACLs are enabled, this command requires a token with the 'alloc-exec',
  'read-job', and 'list-jobs' capabilities for a task's namespace. If
  the task driver does not have file system isolation (as with 'raw_exec'),
  this command requires the 'alloc-node-exec', 'read-job', and 'list-jobs'
  capabilities for the task's namespace.
