timex to Analyze a Command

If you have a specific command you want to find out more about, you can use timex , which reports the elapsed time, user time, and system time spent in the execution of any command you specify.

timex is a good command for users because it gives you an idea of the system resources you are consuming when issuing a command. The following two examples show issuing timex with no options to get a short output of the amount of cpu consumed; the second example shows issuing timex -s to report "total" system activity on a Solaris system:
