In this article, we are going to learn how to calculate and reduce the script’s runtime. A simple
time command will help in calculating the execution time.
Besides having a terminal open, make sure you have the necessary scripts present in your system.
Now, we will write a simple script that contains a few commands, and then, using the
time command, we will get the runtime of that script. Create a script
cal_runtime.sh and write the following code in it.
clear ls -l date sudo apt install python3
How script works
Now, we have written a script
cal_runtime.sh and four commands in that script:
clear, ls, date, and a
python3 installation command. Run your script as follows:
$ time bash cal_runtime.sh
After the execution, you will get the runtime of the script at the bottom of your output.
