How to write daemon in UNIX
Hi Guys,
I hope this is the right forum to post this.
I have a directory where files will be dumped at any time of the day and I want to run scripts as soon as new files come into the directory.
How can I write a daemon that detects when new files have been uploaded to the directory?
Can someone please put some sample codes on how to create daemon with brief explanation.
Thanks very much.

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.
