I have tried reading many things and was never able to clear this up much. I tried man man and as much as I was able to digest of that, I couldn't figure out the answer to the following. What does it mean when a man page underlines something. For example here is a snipit of output from man date.
display time described by STRING, not `now'
Obviously I wanna know more about the format STRING should be in. Is that why its underderlined? Where/how do I get this info? I am actually looking for what I can pass the date parameter in the date command, so if the underline isnt the actual answer, help with that would also be appretiated.
