Sshspass is a very useful tool for running ssh authentication in non-interactive mode. With sshspass, the password of the ssh or scp command can be used without interaction, which helps to use the password in shell scripts. We recommend using key-based authentication instead of using it.

For most of the latest operating systems, the sshpass package is available in the default package repository. You can install it on the system using the following command.

On Debian:

$sudo apt install sshpass

On CentOS:

$yum-- enablerepo = epel-y install sshpass
