How to Give Password Using Echo and Stdin in CentOS

When working in CentOS, you may encounter situations where you need to provide a password using the echo command and stdin. This can be useful for automating tasks or scripts that require password input. Here's how you can do it:

1. Open a terminal in CentOS.
2. Use the following command to echo the password and pipe it to the command that requires the password:

echo 'your_password' | command

3. Replace 'your_password' with your actual password and 'command' with the command that needs the password input.
4. Press Enter to execute the command with the provided password.

It's important to note that storing passwords in plain text or using this method may pose security risks. Exercise caution and consider safer alternatives like key-based authentication for secure password handling.
