I wanted to start learning j, so I downloaded the osx_mac_intel 701 version and noticed that the instructions on running j is to run the jhs701, and follow the link to the webpage where we can interactively play with j. I looked through the bin directory but could not find a command line tool that did not require the web interface. So my question is, is there a commandline tool for j, if not, why not?

Yes, it's called jconsole (or jconsole.exe in Windows) and located in the bin directory.

Why? Because an interactive shell is useful for learning a programming language and testing code.

And the directions on the site suggests that you read the J Primer, which has a Get Started section, which tells you to launch jconsole via the J program icon. It doesn't tell you to run jhs (J HTTP Server), which is a web server/IDE.

jconsole from the bin directory in the 701 download also does not give me an interactive shell, instead it gives me this http://dl.dropbox.com/u/3761620/jconsole.png – Doboy Apr 22 '12 at 16:45
There was a conflict in names of binary that jconsole has, therefore it was running the wrong jconsole. It works now – Doboy Apr 22 '12 at 16:56
@Doboy: Ah, yea, I also came across the Java jconsole when I was doing my research. – Lèse majesté Apr 22 '12 at 17:05
