'tab' is a command-line utility for processing data in tabular text files (think CSV or webserver logs) in a much more serious and rigorous way than 'awk' and friends can.<p>Born out of a real need to compute and aggregate quickly and directly in the shell, without the hassle of having to write Python or Perl scripts. Have fun.<p>[Get it here.](http://bitbucket.org/tkatchev/tab)
