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

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.

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 filedescriptor limit for all processes
  # to 8192.  The soft limit is still 1024, but any unpriviliged
  # process can increase it’s soft limit up to the hardlimit
  # with "ulimit -Sn xxx" (needs a 2.2.13 or later Linux kernel).
  ulimit -Hn 8192

  # Execute the program.
  eval exec "$4"
