For more detailed background information on what file permissions are, see the Wikipedia article on: Filesystem permissions

Most current file systems today have methods of administering permissions or access rights to specific users and groups of users on computers. These permissions control the ability of the users to view and/or make changes to the contents of the files and/or the file directory(folder). To simplfy this explanation here, remember permissions are broken down by the following 3 designations in a Unix/Linux server:

r = Read permissions    (the ability to view the file/files in a directory)
w = Write permissions   (the ability to write to the file/files in a directory)
x = Execute permissions (the ability to execute the file/files in a directory)

Warning!
