This assumes you are familiar with the basic usage of the Gateway Migration Utility. Following is an example of how to list every folder in an API Gateway.

/path/to/GatewayMigrationUtility.sh restman
-host apig.example.com
-port 8443
-username john.doe
-password f5VPX0yUJPg.m4BrjdgMv84UgktddJD3xA
-method GET
-path '1.0/folders'

Or the -argFile option can be used, to reduce the number of options that are used on the command line.

/path/to/GatewayMigrationUtility.sh restman
-argFile example.properties
-method GET
-path '1.0/folders'

Or, a single folder can be returned by including the folder ID.

/path/to/GatewayMigrationUtility.sh restman
-argFile example.properties
-method GET
-path '1.0/folder/ed470defe8384b2fdfcb701c3623de7a'

Or, you can use the -query option to return a single folder by including the name of the folder.

/path/to/GatewayMigrationUtility.sh restman
-argFile example.properties
-method GET
-path '1.0/folders'
-query 'name=example'

The -response option can be used to output the XML to a file.

/path/to/GatewayMigrationUtility.sh restman
-argFile example.properties
-method GET
-path '1.0/folders/ed470defe8384b2fdfcb701c3623de7a'
-response /path/to/myFolder.xml

Something like this should be returned.
