I was a beginner in Linux. And I had no Computer when I wrote this. I used terminal emulator on my Android to run Linux commands. I installed Busybox too. I also had root access.I tried to execute a shell script "sample.sh". The terminal opens but the file was not executed. So I asked "What is the .bat equivalent extension in linux?".
Is this really a very bad question? What was the point in downvoting the question here? I clearly mentioned what I have tried and What happended. And that genuine downvoter never explained the reason. Is this the correct way to treat a newbie. With lots of hatred from my various questions, I lost hope and never used S.O.
So if there is still hope. Can anyone justify the actions?
The equivalent extension is .sh, but you also need the correct shebang line. The first line of a unix script is examined to determine the magic number - you want something like
#! /usr/bin/env bash
And the file needs to have the executable bit set,
chmod a+x file.sh
