What are the functions of sshpass?

sshpass is a command-line tool in Linux that automates the SSH login process, eliminating the need to manually input passwords in scripts. Its main purpose is to simplify SSH login automation.

1. Automated SSH login: You can use the sshpass command in a script to automate the SSH login process and avoid manually entering the password.
2. Provide password parameter: You can use the sshpass command to supply password parameter for automatically entering the password during automated SSH logins.
3. Execute remote commands: In addition to automatic SSH login, sshpass also provides the functionality to execute remote commands, allowing for specified commands to be executed after successful login.
4. Allow interactive mode: sshpass can allow interactive mode when needed, enabling interaction with the remote host during the login process.

It is important to note that since sshpass transmits passwords in plain text, it should be used with caution in terms of security and is not recommended for use in a production environment.
