Commands for channel remove and export are not proper formatted

In Application Platform Installation Methods in the chapter 2.5. Managing JBoss EAP installation channels in Red Hat JBoss Enterprise command are not proper formatted. 

jboss-eap-installation-manager channel remove --channel-name <CHANNEL_NAME> --dir eap-8

it should be 

./jboss-eap-installation-manager.sh channel remove --channel-name <CHANNEL_NAME> --dir eap-8 

could you please check it?
