How does Linux grant full permissions to users?

In the Linux system, users can grant full permissions using the chmod command.

1. show the long listing of files and directories

ls -l myfile.txt

1. change the file permissions

chmod u+rwx myfile.txt

In the command above, ‘u’ represents the file owner and ‘rwx’ represents read, write, and execute permissions. If you want to give all users full permissions, you can use ‘a’ to represent all users, for example:

chmod a+rwx myfile.txt

Giving users full permission may lead to security issues. It is recommended to allocate appropriate permissions to users based on their actual needs.
