3-minute quick fix! Check permissions,ShebangLine and file encoding, completely solving the script execution problem,Linux/A must-read for Mac users!

Have you ever scratched your head in front of your computer screen because of a "cannot execute: required file not found"mistake?

This is so frustrating!

The file is clearly there, but the system ignores it.

Does the file really exist?

First, we need to confirm, does the file really exist?

Is it put in the wrong place?

It's like you hid your keys so well that you can't find them anymore.

use ls -l check_htaccess.sh Look, is it lying there quietly?

Give it the power to execute!

If the file does exist, it's probably a permissions issue.

Think about it, how can someone without a pass enter? restricted area What?

Giving your script execute permissions is like giving it a VIP pass.

chmod +x check_htaccess.sh You deserve this spell.

Shebang, the mysterious spell

The first line of the script,#!/bin/bash, like a mysterious spell.

It tells the system to use bash to execute this script.

If the spell is written incorrectly, the system will of course be confused.

Check to make sure the spell is intact and has not been secretly modified.

Windows Gotchas

If you are creating scripts under Windows, be careful about line breaks.

Windows and Linux have different line endings, just like two different languages.

dos2unix check_htaccess.sh This command can help you translate and avoid communication barriers.

File format, right?

use file check_htaccess.sh Check the file format.

Make sure it's an executable text file and not something weird.

Just like you can't use a bottle opener to open a can.

Explore deeply and get to the bottom of things

In addition to the above points, there are some deeper reasons.

For example, are your system environment variables set correctly?

Are some dependent libraries missing?

These all require you to explore further and unravel the mystery like a detective.

Only by unraveling the mystery can we find the end

In my opinion, the key to solving this problem lies in detailed investigation.

From the most basic file existence to the complex system environment, we need to review them one by one. 

This is just like a doctor diagnosing a disease. It requires rich experience and knowledge to find the root cause of the disease.

Conclusion: Clear the fog and see the light

"cannot execute: required file not found” Although this error may seem scary, it can be easily solved if we analyze it calmly and find the root cause of the problem.

Remember, file existence, execution permissions, Shebang, file format, system environment, these are the key points we need to pay attention to.

I hope this article can help you solve the problem and move forward courageously on the road of programming!
