INITSCRIPT(5)						Linux System Administrator's Manual					     INITSCRIPT(5)

NAME
       initscript - script that executes inittab commands.

SYNOPSIS
       /bin/sh /etc/initscript id runlevels action process

DESCRIPTION
       When  the  shell  script /etc/initscript is present, init will use it to execute the commands from inittab.  This script can be used to set
       things like ulimit and umask default values for every process.

EXAMPLES
       This is a sample initscript, which might be installed on your system as /etc/initscript.sample.

	      #
	      # initscript   Executed by init(8) for every program it
	      # 	     wants to spawn like this:
	      #
	      # 	     /bin/sh /etc/initscript <id> <level> <action> <process>
	      #

		# Set umask to safe level, and enable core dumps.
		umask 022
		ulimit -c 2097151
		PATH=/bin:/sbin:/usr/bin:/usr/sbin
		export PATH

		# Increase the hard file descriptor limit for all processes
		# to 8192.  The soft limit is still 1024, but any unprivileged
		# process can increase its soft limit up to the hard limit
		# with "ulimit -Sn xxx" (needs a 2.2.13 or later Linux kernel).
		ulimit -Hn 8192

		# Execute the program.
		eval exec "$4"

NOTES
       This script is not meant as startup script for daemons or somesuch.  It has nothing to do with a rc.local style script. It's just a handler
       for things executed from /etc/inittab. Experimenting with this can make your system un(re)bootable.

FILES
       /etc/inittab, /etc/initscript.
