How to solve the problem of insufficient permissions of the current directory in linux

How to solve the problem of insufficient permissions in the current directory of linux? I believe that many inexperienced people are at a loss about this, so this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Solution:

Sudo-s # enters root user mode and remains in the original directory (do not use su-root, otherwise you will enter the root directory) cd / var/lib # enter the specified directory ll # to view all the file permissions in this directory chmod 777 files-name # change the permissions of the specified files

R indicates that the file can be read (read)

W indicates that the file can be written (write)

X indicates that the file can be executed (if it is a program)

Among them: rwx can also be replaced by numbers

R-4

W-2

X-1

-0

-rw--- (600) only the owner has read and write permission

-rw-r-r- (644) only the owner has read and write access, and groups and others only have read permission

-rwx-- (700) only the owner has the permission to read, write and execute

-rwxr-xr-x (755) only the owner has read, write, and execute permissions, and groups and others only have read and execute permissions

-rwx-x-x (711) only the owner has the permission to read, write, and execute, and groups and others only have the permission to execute

-rw-rw-rw- (666) everyone has read and write access

-rwxrwxrwx (777) everyone has access to read, write and execute

How does "755" form: "0" indicates no permission, "1" indicates executable permission, "2" indicates writeable permission, and "4" indicates readable permission. "7 million 1 2 4 5 # 1 4"
