Homework 1:

Due Feb 1, 2000 right after intermission.

Using the template for "rc" given in class:

  for file in /etc/rc$runlevel.d/K??*
  do
    sh $file stop
  done

  for file in /etc/rc$runlevel.d/S??*
  do
    sh $file start
  done

write a fully functional one.  It should require an
argument (the runlevel), make sure the directories
exists, and then do the above task.  Don't use the
root directory, but use something under your home
directory (ie don't use /etc, use $HOME/cs501/hw1/etc)
using a variable setting at the top of your "rc":

  ROOTDIR=$HOME/cs501/hw1

  for file in $ROOTDIR/etc/rc$runlevel.d/K??*
  ...

Also, write an init.d script to use with your "rc"
script.  Use a fake program "foo" as the service
to start.  Imagine that it stores its PID in
$ROOTDIR/var/run/foo.pid

If you are having a hard time imagining such an
application, use the foo.c that I wrote:

Homeworks should be printed, not handwritten.  Points
will be given as follows (nothing in between):

  5  - Both scripts are right
  3  - One script is right
  1  - Neither script is right.
