# Command: job revert
The `job revert` command is used to revert a job to a prior version of the
job. The available versions to revert to can be found using [`job
history`](/docs/commands/job/history.html) command.
The revert command will use a Vault token with the following preference:
first the `-vault-token` flag, then the `$VAULT_TOKEN` environment variable.
Because the vault token used to [run](/docs/commands/job/run.html) the targeted
job version was not persisted, it must be provided to revert if the targeted
job version includes Vault policies and the Nomad servers were
[configured](/docs/configuration/vault.html#allow_unauthenticated)
to require authentication.
## Usage
```
nomad job revert [options] <job> <version>
```
The `job revert` command requires two inputs, the job ID and the version of that job
to revert to.
## General Options
<%= partial "docs/commands/_general_options" %>
## Revert Options
* `-detach`: Return immediately instead of monitoring. A new evaluation ID
will be output, which can be used to examine the evaluation using the
[eval status](/docs/commands/eval-status.html) command
* `-vault-token`: If set, the passed Vault token is sent along with the revert request
to the Nomad servers. This overrides the token found in the $VAULT_TOKEN environment
variable.
* `-verbose`: Show full information.
## Examples
Revert to an older version of a job:
```
$ nomad job history -p example
Version = 1
Stable = false
Submit Date = 07/25/17 21:27:30 UTC
Diff =
+/- Job: "example"
+/- Task Group: "cache"
+/- Task: "redis"
+/- Config {
+/- image: "redis:3.2" => "redis:4.0"
port_map[0][db]: "6379"
}
Version = 0
Stable = false
Submit Date = 07/25/17 21:27:18 UTC
$ nomad job revert example 0
==> Monitoring evaluation "faff5c30"
Evaluation triggered by job "example"
Evaluation within deployment: "e17c8592"
Allocation "4ed0ca3b" modified: node "e8a2243d", group "cache"
Evaluation status changed: "pending" -> "complete"
==> Evaluation "faff5c30" finished with status "complete"
