Question

I have a lots of short programs in C. Each program realize simple operation for example: include library, load something (ex matrix) from file, do simple operation, write matrix to file end.

I want to measure real time of excecution a whole program (not only fragment of code).

My simple idea is using htop or ps aux -> column time. But this method isn’t good because I don’t have exacly time of execution but time of excecution during last refresh and I can miss this.

Do you have any method to measure time of process in linux?

Answer 1

If your program is named foo, then simply typing

~$ time foo

should do exactly what you want.
