title: Finding punctuation and counting the number of each from the Unix Command line
body: <p>I want find all of the punctuation marks used my <code>.txt</code> file and give a count of the number of occurrences of each one. How would I go about doing this?? I am new at this but I am trying to learn!  This is not homework! I have been doing research on <code>grep</code> and <code>sed</code> right now.</p>
