The time Command

The time command is a built-in command in the Korn shell and functions the same as the Unix times command. Here, the ls command is timed. It indicates the amount of elapsed, user, and system time spent executing the ls command:

					$ time ls /usr/spool/uucppublic
					mail
					real    0m0.33s
					user    0m0.05s
					sys     0m0.18s
