Permission management in Linux


You can assign rights in Linux by using command chown. It’s easy, all you need is to know which file/s or folder/s you need to assign the permission, and you have right to do so (for instance if you are root user).

This example shows how to assign user1 permission on folder /test. To do so type: chown user1 /test.

You can clearly see that folder is set to 777 permission.

To process bundle action with folders and sub folders use the following example: chmod –R /test. This will setup all folders, files and subfolders to 777.

However there might be another way to do it either for folders&subfolders: find /test/ -type d -exec chmod 777 {} \;

or for the all files in all folders and subfolders: find /var/www -type f -exec chmod 777 {} \;

Be very careful with permission 777, this is shown only for example purposes.
