     Output prefixes: `+` (add), `-` (delete), `M` (modify), `R` (rename). Use `-p`, `-t` for pagination.
     Manage diff jobs: `ozone sh snapshot listDiff /vol1/bucket1`, `ozone sh snapshot cancelDiff <jobId>`.
 
+*   **List Snapshot Diff Jobs:** Lists snapshot diff jobs for a bucket.
+    ```shell
+    ozone sh snapshot listDiff /vol1/bucket1
+    ```
+    By default, lists jobs with `in_progress` status. Use `--job-status` to filter by specific status:
+    ```shell
+    # List jobs with specific status (queued, in_progress, done, failed, rejected)
+    ozone sh snapshot listDiff /vol1/bucket1 --job-status done
+    ```
+    Use `--all-status` to list all jobs regardless of status:
+    ```shell
+    # List all snapshot diff jobs regardless of status
+    ozone sh snapshot listDiff /vol1/bucket1 --all-status
+    ```
+    **Note:** The difference between `--all-status` and `-all` (or `-a`):
+    * `--all-status`: Controls which jobs to show based on status (lists all jobs regardless of status)
+    * `-all` (or `-a`): Controls the number of results returned (pagination option, removes pagination limit, **not related to snapdiff job status**)
+
+    For example:
+    ```shell
+    # List all jobs regardless of status, with pagination limit removed
+    ozone sh snapshot listDiff /vol1/bucket1 --all-status -all
+    # Or limit results to 10 items
+    ozone sh snapshot listDiff /vol1/bucket1 --all-status -l 10
+    ```
+
 *   **Rename Snapshot:**
     ```shell
     ozone sh snapshot rename /vol1/bucket1 <oldName> <newName>
