Shell Script on Boot up does not execute on Raspberry pi

Question

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

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

I created the following files and ran the following steps:

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"
    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

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.

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.

sudo is pointless and potentially harmful here. An init script already has all the privileges it needs. — tripleee

Put the compiled binary into /usr/local/bin and change the script to run it from there. Examine your system log for failure or warning messages. Post them here if you need help interpreting them. — tripleee

Hi it worked thanks ... I put the executable in the /usr/local/bin folder... I was not providing the file path properly...i guess it would have worked with /home/pi/wifiserver.o as well since my executable was present there. Thanks!! @tripleee — RootPhoenix

Post the fixed script as an answer and accept it so that this question no longer shows up as unresolved. Thanks. — tripleee
