Duplicate argument '--command'/'--commands' exception while executing CLI command in JBoss EAP 6 ?

Issue

We are trying to connect to JBoss EAP instance using the jboss-cli.sh script specifying a username, password, and command on the command line, but it failed with exception

Duplicate argument '--command'/'--commands' 

Can you tell me how to run a command like the following from a non-interactive command line?

$JBOSS_HOME/bin/jboss-cli.sh --connect --controller=host:9999 --command="undeploy" --username=user --password=password

$JBOSS_HOME/bin/jboss-cli.sh --connect --controller=host:9999 --user=user --password=pass  --file /home/cli_input
