Question

I’ve written a C++ program of which i would like to time the length of time it takes to complete – is there some terminal command i could use?

Answer 1

You can use the “time” command available in most (maybe all) the linux distributions. It will print the time spent as system, as user, and the total time.

For example

bash-4.1$ time (sleep 1; sleep 1)

will output something like

real    0m2.020s
user    0m0.014s
sys 0m0.005s

As you can see with the parenthesis you can launch every command chain you wish.
