Let me describe a bit more:

Here's what I normally do as per how-to-run-news.txt

mzscheme -f as.scm

I get the mzscheme prompt. I type:

(load "news.arc") (nsv)

It runs well, so far so good, but I have the interactive interpreter. As soon as I shut down, the service disappears.

To run it as a shell script I looked at mzcheme man page and tried to run the following in a script called run_hacker_news.sh:

[script starts] #! /bin/sh #|

exec /home/bahadir/mz/bin/mzscheme -f as.scm |# (load "news.arc") (nsv) [script ends]

This doesn't work. I just want to run it and logout so it stays running. It's a linux box. Thanks a lot.

This is where 'screen' comes in handy. Screen is a threaded model: it assigns a single thread for each 'screen' used. It also has a built in command to detach from your screen session (CNTRL+a d). After detaching you can then close the terminal window and arc will still be running as a silent thread. To get back just launch screen with the option to re-attach ($ screen -x).

The parts with parenthesis () are multi-line, the post is displayed as single line somehow.

You need an extra line break to separate lines.

  Or indent a line by at least two spaces to get text verbatim.
