## Syntax {#syntax}

The [`mc support top locks`](#command-mc.support.top.locks) command lists the ten oldest [locks](/administration/object-management/object-retention/#minio-object-locking) on a MinIO deployment.

The command outputs the age of the lock, type of lock, owner, and resource. The output resembles the following:

```shell
Since                 Type    Owner                 Resource
13 hours ago          WRITE   10.68.100.18:9000     .minio.sys/leader.lock
13 hours ago          WRITE   10.68.100.18:9000     .minio.sys/callhome/runCallhome.lock
13 hours ago          WRITE   10.68.100.23:9000     .minio.sys/new-drive-healing/0/0
```

**EXAMPLE**

The following command displays the current in-progress S3 API calls on the [alias](/glossary/#term-alias) `myminio`.

```shell
mc support top locks myminio/
```

**SYNTAX**

The command has the following syntax:

```shell
mc [GLOBALFLAGS] support top locks  \
                 [--stale]          \
                 TARGET
```

- Brackets `[]` indicate optional parameters.
- Parameters sharing a line are mutually dependent.
- Parameters separated using the pipe `|` operator are mutually exclusive.

Copy the example to a text editor and modify as-needed before running the command in the terminal/shell.
