[antlr-interest] query regarding lexer

I need to neglect other lexer rules when I encounter a lexical token.
The following snippet works for me. But I am sure there should be a better
way of doing this.
commandline : CMD ' ' CMD_ARG;
CMD : 'command'
CMD_ARG : ('a'..'z' | 'A'..'Z' | '0'..'9' | ' ' | '/')* ;
Ex :
command blah blah blah blah..
should parse resulting two tokens 1) command and 2) rest of the string (blah
blah blah blah..). this can include any special character
Any help will be greatly appreciated.
