Measure the running time of any command

Solution

$ time any-command-to-run

Example

For the following command:

$ time ./init_my_project.sh

After the script finished running, you’ll see:

real    1m37.121s
user    0m44.342s
sys     0m12.518s

Where

• real means the elapsed real (wall clock) time used by the process, in seconds.
• user means the total number of CPU-seconds that the process used directly (in user mode), in seconds.
• sys means the total number of CPU-seconds used by the system on behalf of the process (in kernel mode), in seconds.
