Re: [ros-dev] Something "wrong" in hostname

hostname behaves like the following on XP (polish localized copy, 
messages may differ):

if(no parameter line given) {
	print hostname()
} else {
	if(parameter line begins with "-") {
		if(parameter == "-s")
			print hostname() . "\n"
		else
			print "Invalid option. \n\n Prints current host name. \n\n hostname \n"
	}
	else
		print "sethostname: Use Control panel applet to set hostname. \n 
hostname -s is not supported. \n"
}
