What if permission denied appears in Linux?

This article will explain in detail what to do about permission denied in Linux. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

Permission denied:

The reason is that there is no permission to read, write, create files, delete files, and so on.

Solution: enter the command sudo chmod-R 777 / working directory

For example, sudo chmode-R 777 / home/HDD, a series of operations can be performed under this path.

Sudo: a linux system management instruction that allows system administrators to allow ordinary users to execute some or all of the root commands.

-R: refers to all the subdirectories and files in the directory

777: refers to the highest permissions that all users have.

But it is inconvenient and not suitable for beginners. The simple and rude methods are as follows:

Enter on the command line

Sudo passwd

He will prompt you to enter the new password, enter the password again, just enter the same as before, and after success, enter

Su root

Just enter the password again ~

At this time, you will find that the $sign before you enter the command has become the # sign, which proves that you have succeeded.
