title: bash script for apending dates onto files
body: <p>I am trying to write a bash script which takes in a file as $1 and then copies it and appends the year,month, and date onto the end of the file. So for example if i had a file foo.txt it would turn into foo.txt.2010.11.16. I'm not really 100% sure how to do this, any suggestions?</p>
