ow do I pass an additional command line option to my OpenSSH client for password? I need to pass the both usename and password on the command line as follows:

ssh user@server.nixcraft.net.in myPasswordHere "command1"

How do I pass a password to ssh client under Linux or UNIX operating systems?

You need to use the sshpass command. It is a utility designed for running ssh using the mode referred to as "keyboard-interactive" password authentication, but in non-interactive mode. You can install it as follows:

$ sudo apt-get install sshpass

And pass the password as follows:

$ sshpass -p 'mySSHPasswordHere' ssh username@server.nixcraft.net.in "uptime"

OR

$ sshpass -p 'PASSWORD' ssh -o StrictHostKeyChecking=no username@server.nixcraft.net.in "who"
