Shell Script on Boot up does not execute on Raspberry pi

I want to run the following commands just after bootup of Raspberry Pi running the raspbian wheezy:

1. sudo gcc -lpthread server.c -o wifiserver.o
2. sudo ./wifiserver.o

I created the following files and ran the following steps:

1. Created a script file named auto_server_start.

2. Contents are as follows:

   #!bin/bash
   # /etc/init.d/auto_server_start
   ### BEGIN INIT INFO
   # Provides: auto_server_start
   # Required-Start: $all
   # Required-Stop: $remote_fs $syslog
   # Default-Start: 2 3 4 5
   # Default-Stop: 0 1 6
   # Short-Description: wifi server script
   # Description: Start wifi server at bootup
   ### END INIT INFO
   
   case "$1" in
     start)
       echo "running server program"
       sudo gcc -lpthread server.c -o wifiserver.o
       sudo ./wifiserver.o
       ;;
     stop)
       echo "stopping customized script"
       ;;
     *)
       echo "Usage: /etc/init.d/auto_server_start start|stop"
       exit 1
       ;; 
   esac
   
   exit 0
   

3. Copied this file named auto_server_start to /etc/init.d/ directory and added execute permission using chmod +x.

4. Then sudo update-rc.d auto_server_start defaults.

It gave some warning about mathkernel but I don't think that has anything to do with my script.

However on soft reboot I checked ps -e as well as top, nowhere does my wifiserver process show up.

Please suggest.

PS: I checked that the commands gcc and ./wifiserver.o were giving no warning and errors.

Created a script file named auto_server_start.

Contents are as follows:

\#!bin/bash

\# /etc/init.d/auto_server_start

\### BEGIN INIT INFO

\# Provides: auto_server_start

\# Required-Start: $all

\# Required-Stop: $remote_fs $syslog

\# Default-Start: 2 3 4 5

\# Default-Stop: 0 1 6

\# Short-Description: wifi server script

\# Description: Start wifi server at bootup

\### END INIT INFO


case "$1" in

  start)

    echo "running server program"

    /usr/local/bin/wifiserver.o

    ;;

  stop)

    echo "stopping customized script"

    ;;

  *)

    echo "Usage: /etc/init.d/auto_server_start start|stop"

    exit 1

    ;; 

esac


exit 0

Copied this file named auto_server_start to /etc/init.d/ directory and added execute permission using chmod +x.

Then sudo update-rc.d auto_server_start defaults.
