+# unwrap
+
+The `unwrap` command unwraps a wrapped secret from Vault by the given token. The
+result is the same as the "vault read" operation on the non-wrapped secret. If
+no token is given, the data in the currently authenticated token is unwrapped.
+
+## Examples
+
+Unwrap the data in the cubbyhole secrets engine for a token:
+
+```text
+$ vault unwrap 3de9ece1-b347-e143-29b0-dc2dc31caafd
+```
+
+Unwrap the data in the active token:
+
+```text
+$ vault auth 848f9ccf-7176-098c-5e2b-75a0689d41cd
+$ vault unwrap # unwraps 848f9ccf...
+```
+
+## Usage
+
+The following flags are available in addition to the [standard set of
+flags](/docs/commands/index.html) included on all commands.
+
+### Output Options
+
+- `-field` `(string: "")` - Print only the field with the given name. Specifying
+  this option will take precedence over other formatting directives. The result
+  will not have a trailing newline making it idea for piping to other processes.
+
+- `-format` `(string: "table")` - Print the output in the given format. Valid
+  formats are "table", "json", or "yaml". This can also be specified via the
+  `VAULT_FORMAT` environment variable.
