How do I pass password to sudo commands?

If you want to run a sudo command without being prompted to input the password you can do the following command.

echo password | sudo -S rm -rf /opt/jetty/

The -S (stdin) option allow the sudo command to read password from a standard input instead of a terminal device.

If you want to store the password in a file you can use the cat command instead of echo like the following example.

cat password.txt | sudo -S rm -rf /opt/jetty/
