Lock the current terminal session?
There might be an obvious answer to this, but it's not coming to me.
Is there any way to lock the terminal session so no commands can be entered at the prompt without a password verification?
For example, I'm have to leave my machine for a few minutes, but I don't want to completely close my SSH session. But I also don't want prying fingers rumaging through /bin while I'm gone.
Is there anythign built in to bash? Can I download something?
