Linux Commands: Measure Program Resource Use


time-Linux Command

time command- Measure Program Resource Use

Syntax:
Description: It is used to time command executions. If you have some command that takes a fair amount of time to execute, and you do not feel like standing by with a stopwatch, you can see how long it took by running the command as argument to time.

Beware of the time command. This is not used to get the system time. Instead it's used to time how long something takes. Refer the time man page. Outputs verbose timing statistics for executing a command.
time ls -l / gives something like this:

Example:
 $ time sleep 60


 real 1m0.045s


 user 0m0.000s


 sys 0m0.000s
