Quick and dirty stopwatch via the Mac Terminal (works on any *NIX system, Id guess)

You can create an instant quick and dirty stopwatch via the Mac OS X command line by launching Terminal and typing:

time cat

then hit enter and the stopwatch begins, you can stop the count by hitting Control-C, which will return something back that looks like this:

$ time cat
^C
real    0m5.905s
user    0m0.001s
sys 0m0.003s
