**-h, --help**  
Shows the help text for `pcluster-config convert`.

**-c *CONFIG\$1FILE*, --config-file *CONFIG\$1FILE***  
Specifies the path of the configuration file to read.  
Defaults to `~/.parallelcluster/config`.  
For more information, see [Configuring AWS ParallelCluster](getting-started-configuring-parallelcluster.md).

**-t *CLUSTER\$1TEMPLATE*, --cluster-template *CLUSTER\$1TEMPLATE***  
Indicates the [`[cluster]` section](cluster-definition.md) to use. If this argument is not specified, `pcluster-config convert` will use the [`cluster_template`](global.md#cluster-template) setting in the [`[global]` section](global.md). If that isn't specified, then the `[cluster default]` section is used.

**-o *OUTPUT\$1FILE*, --output *OUTPUT\$1FILE***  
Specifies the path of the converted configuration file to be written. By default, the output is written to `STDOUT`.

Example:

```
$ pcluster-config convert -t alpha -o ~/.parallelcluster/multiinstance
```

Converts the cluster configuration specified in the `[cluster alpha]` section of `~/.parallelcluster/config`, writing the converted configuration file to `~/.parallelcluster/multiinstance`.
