Hi,

I am interested in running a lisp process to handle connections to a
port on a server using ACL5.0.1. I would like this startup process to
be automatic, but also have the ability to restart the lisp process
like a daemon without rebooting the machine. I have gotten this far:

Added the line -
lisp -L load.cl &
to a startup file on my Sun Solaris system.

This is the first half of my solution. I can then find the PID of the
lisp process, and kill it to stop the daemon, but I'm not sure how to
recreate the process in the background again. That is, if I use the
same line - 
lisp -L load.cl &
the system will run fine until I close my terminal session - at which
point the lisp process dies. Does anyone have any suggestions or
experiences with this type of situation?

Thanks,
Jonathan

I do this on the ALU web site:

# this line is in /etc/rc.local;  "alu" is the user the lisp process
# runs as.
su alu -c /var/www/alu/start-cl-http

# /var/www/alu/start-cl-http is this
exec lisp -L lisp/start.lisp </dev/null >/tmp/cl-http.log 2>&1 &

A telnet server I load into the lisp lets me interact with a REPL
when I need to.

use nohup (or launch from csh/tcsh which, in contrast to sh/bash,
don't require nohup).

(You may also e.g. consider redirecting input from /dev/null)

Have you tried nohup? (man nohup is a good place to start)...
