File Permissions

Learn how linux file permission works. Chmod, chown and chgrp commands explained with examples.


In linux, files have many attributes. We can execute the following command in the command line to view them: ls -l

This command will list all files in the current directory. Each line is a file ie:

-rwxrwxrwx 1 root root 9580 abr 30 14:48 myfile
is the type of file.
rwxrwxrwx is the permission of the file. We will see how they work later on this article.
1 is the number of hard links
root root the first root is the user owner of the file, and the second refers to the group.
9580 is the file size
abr 30 14:48 is the date and time of the last modification of the file.
myfile is the name of the file.
