I need to execute this command on the RASPBERRY PI bootup 

cd RPi_Cam_Web_Interface && ./install.sh

and also follows dual ENTER keys with 5 seconds interval for each.

    Why do you want to run an install script at every startup? You would normally install just once! – CoderMike Feb 11 at 18:51
  • its an pi-Cam web interface , which shows live preview from the picam. but it is not starting at BOOT , even though the auto start is enabled – Reaghan Pius Feb 12 at 12:31
  • What happens when you enter 'cd RPi_Cam_Web_Interface' then './start.sh' ? – CoderMike Feb 12 at 13:56
  • when entered ./start.sh it just skips to the next line without executing anything – Reaghan Pius Feb 12 at 17:53

thanks People, i finally made it work by using this below command: \cd /home/pi/RPi_Cam_Web_Interface && ./install.sh and saved this as an Script and finally mentioned this script at the botom line of "sudo nano .bashrc" and now when i boot my pi,the software is installed freshly.

  • Seems like this would only run when you log in, not when you boot. – Glen Yates Feb 13 at 17:41

There are a few ways to execute a boot command. I use the rc.local file. sudo nano /etc/rc.local Add your shell command before the exit 0

for entering two enter keypress you can something along the lines of

cd RPi_Cam_Web_Interface && ./install.sh
echo | <yourfinecommandhere>
sleep 5s
echo | <yourfinecommandhere>

  • Please take note that using /etc/rc.local has limitations due to Compatibility with SysV. Following the recommendation of the developers from systemd you should avoid using it. – Ingo Feb 11 at 22:16
  • I think the OP has misunderstood how RPi-Cam-Web-Interface works. – CoderMike Feb 12 at 13:58

I believe you could also use sudo crontab -e and just add a command with the absolute path (/usr/bin/foo). To run a command at boot and reboot in the background (so it doesn't prevent pi from continuing boot), add @reboot /usr/bin/foo&
