The 'time' command

       The 'time' command is one of those utilities you discover one day and 
       you just can't help wondering: How come I didn't know about it?
       
       In short, if you prepend 'time' to any other command, the time command
       will tell you how long that other command took to complete. It sounds 
       simple but it is absolutely handy in certain/many occasions.
       
       I discovered it thanks to Ben Armstrong. He told me about it when I 
       was using an online stopwatch to control the time of certain processes
       and well, the online service did the trick to approximately measure 
       the time but with the time command you get the exact amount of time.
       
       It is really great to learn something new. That's why I wanted to post
       about it.
       
       Thanks :)
