A mini (micro?) video with a few lines of Bash on Linux, following my introduction to the "SECONDS" variable, which you can find here: https://youtu.be/4Q9adopz82E .
I decided to make a small elapsed-time "display" for a Bash shell script, with a configurable maximum duration (it can also be used as a sleep function with a display before starting another task, for example). In short, a few lines of Bash just for fun ;)
