[SOLVED] Unix Command For Benchmarking Code Running K times

Issue

Suppose I have a code executed in Unix this way:

$ ./mycode

My question is is there a way I can time the running time of my code executed K times. The value of K = 1000 for example.

I am aware of Unix "time" command, but that only executed 1 instance.

Solution

try

$ time ( your commands )

write a loop to go in the parens to repeat your command as needed.

Update

Okay, we can solve the command line too long issue. This is bash syntax, if you're using another shell you may have to use expr(1).

$ time (
> while ((n++ < 100)); do echo "n = $n"; done
> )

real    0m0.001s
user    0m0.000s
sys     0m0.000s
