That link is a good start. There are some hooks in the system to determine if the called script is being invoked from a terminal or not (perhaps as a CGI call in a web page). This is useful for dealing with -parms and piped expressions in the *nix environment. If that is of interest, you can f

Re: [Jprogramming] Running script from jconsole

Very nice! I did run into a little frustration in OS X Terminal - where jconsole is by default a tarpit of java stuff. So either the path to jconsole in the J bundle, or an alias (I do a symbolic link of ja to be jconsole) removes my angst. Examples (in reverse order): $ ja -js 'echo %. i.2
