Description On Unixlike operating systems, a set of flags associated with each file determines who can access that file, and how they can access it These flags are called file permissions or modes, as in "mode of access" The command name chmod stands for "change mode" It restricts the way a file can be accessedNote The chmod command can accept numeric integers, such as 0664, which relate to user permissions See this to help create these, if you wish I will cover using chmod Chmod is used to modify the permissions of a directory or fileTo change directory permissions for everyone, use "u" for users, "g" for group, "o" for others, and "ugo" or "a" (for all) chmod ugorwx foldername to give read, write, and execute to everyone chmod a=r foldername to give only read permission for everyone How to Change Groups of Files and Directories in Linux
