As for ssh, To automate/script it's usage with no success. There doesn't seem to be any build-in way to pass the password into the command without prompting. As others have mentioned, the "expect" utility seems like it is aimed at addressing this dilemma but ultimately, setting up the correct private-key authorization is the correct way to go when attempting to automate this.
Linux - Solution 2:
Applescript which prompts for a password through a dialog box and then builds a custom bash command, like this:
echo <password> | sudo -S <command>click below button to copy the code. By - Linux tutorial - team
If sudo accepted a pre-encrypted password, so you could encrypt it within script and not worry about echoing clear text passwords around.
Linux - Solution 3:
For ssh you can use sshpass -p "password" ssh user@host sshpass works. You need to download sshpass firs

ssh user@host bash -c "echo mypass | sudo -S mycommand"click below button to copy the code. By - Linux tutorial - team
