I have an audio file, and I am running a script to decode that audio file. Now I want to measure the latency of the system. So, I am running a script with a time command. like $ time ./uber.sh In the script uber.sh the file path to the audio file has been mentioned. Now I want to check, the latency when there will be the same audio file 100,1000 and 10000 times. Initially, I am thinking about actually copying the same audio file 100,1000,10000 times and run the script again to measure time.

Is there any other method, in which I should not copy the same audio file multiple times (like 100 to 10000 times) and measure the time. But it will run the script for a single file, multiple times.

    You haven't made it clear why you need to physically copy (create a copy of) this file multiple times. Commented Jun 8, 2021 at 13:20

Are you asking how to create a loop in bash shell/terminal?

Example:

for ((i=0; i<1000; i++)); do date --iso=ns; echo $i; time sleep 0.1s; done

And if you feel like it, you can replace all semicolons with line feeds. And with bash the command line usage uses the same syntax as scripts so you can just put that in a text file and chmod a+x myfilename to turn it into executable script.
