sshpass

An SSH password provider. It works by creating a TTY, feeding the password into it, and then redirecting stdin to the SSH session. More information: https://manned.org/sshpass.

• Connect to a remote server using a password supplied on a file descriptor (in this case, stdin):

sshpass -d 0 ssh user@hostname

• Connect to a remote server with the password supplied as an option, and automatically accept unknown SSH keys:

sshpass -p password ssh -o StrictHostKeyChecking=no user@hostname

• Connect to a remote server using the first line of a file as the password, automatically accept unknown SSH keys, and launch a command:

sshpass -f path/to/file ssh -o StrictHostKeyChecking=no user@hostname "command"
