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.

4Why do you want to run an install script at every startup? You would normally install just once! – CoderMike Feb 11 '19 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 '19 at 12:31

What happens when you enter 'cd RPi_Cam_Web_Interface' then './start.sh' ? – CoderMike Feb 12 '19 at 13:56

when entered ./start.sh it just skips to the next line without executing anything – Reaghan Pius Feb 12 '19 at 17:53

This is a typical X/Y problem. Rather than asking about the workaround you invented, explain your original issue (pi-Cam web interface not starting at boot?) and see what alternative solutions are possible. – Dmitry Grigoryev Mar 6 '19 at 15:38
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.

Please accept your answer with a click on the tick on the left side. This will finish the question and it will not pop up again months for months. – Ingo Nov 24 '19 at 18:48
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>

1Please take note that using
/etc/rc.localhas limitations due to Compatibility with SysV. Following the recommendation of the developers from systemd you should avoid using it. – Ingo Feb 11 '19 at 22:16 -

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&
Add theat command in .bashrc file and it will do
