Top Forums Shell Programming and Scripting daemon scripts Post 73394 by tom_xx_hu@yahoo on Tuesday 31st of May 2005 11:15:55 PM

In many ways, daemon is similar to background process without controlling terminal. However, there are more implications for a daemon: almost idle if no request to work on, listen to (actually, waken by via sth else) a request coming from either a TCP/UDP port, or a signal, multithread or multiprocess based application.

So simply saying making a script a daemon may not make sense in many scenarios. Due to the nature of daemon, people rarely uses script to write a daemon application.

Hope it clarifies,

Tom

lsmsad

lsmsad(8)						      System Manager's Manual							 lsmsad(8)

NAME

       lsmsad - Starts the Storage Administrator (SA) daemon

SYNOPSIS

       /usr/sbin/lsmsad

DESCRIPTION

       The SA daemon, lsmsad, is a process required by lsmsa, the SA graphical user interface (GUI). The daemon issues commands and obtains system
       information on behalf of SA.

       The SA daemon runs on a Tru64 UNIX system on which LSM is initialized and running.  The SA client runs on any  machine  that  supports  the
       Java Runtime Environment.

       The SA daemon is automatically started at boot time. Under normal conditions, the daemon does not need to be run manually.

       If SA does not start during the boot process, enter:

       /sbin/init.d/lsmsa stop

       To restart SA, enter:

       /sbin/init.d/lsmsa start

       Only one SA daemon can be running on a system at a given time. If a second SA daemon attempts to start, it will fail.

RESTRICTIONS

       You must be root user to run lsmsad.

FILES

       The script that starts lsmsad at boot time.  The command log file that tracks SA tasks.	The access log file that tracks login to  SA.  The
       server log file that tracks server startup information and server errors.  The log maintenance shell script that saves and  compresses  log
       files.
