Changing the SSL Port in 10 GAS Release 2

I'm trying to change the default SSL port. The documentation says to = first alias portconfig via the comand

alias portconfig '$ORACLE_HOME/jdk/bin/java -cp \
$ORACLE_HOME/sysman/webapps/emd/WEB-INF/lib/emd.jar: \
$ORACLE_HOME/dcm/lib/dcm.jar: \
$ORACLE_HOME/sso/bin/ssoreg.jar \

oracle.sysman.ias.sta.tools.PortConfigCmdLine \!*'

The backslahes I put in to escale the linefeeds. I've tried it without = them and also tried entering the command on a single line. The result = is always
