CHMOD is used to Assign file permissions and file security settings critical to the safty adn survival of your website. It is important to understand permissions and how they need to be applied. e.g. Directories created under web directories will have different permissions than data file or cached files stored under data directories.

Use the ls -al command to view file permissions. Change file permissions using the chmod command. The chmod command can be used to change the read, write and execute permissions for the owner, user, group and others.

Groups of users can be assigned as:

u (user) you, the owner of the account
g (group) assigned by the system administrator
o (other) everyone else not you, and not in your group
and permissions can assigned as:

r (read) allows your files to be seen and copied
w (write) allows the files to be changed
x (execute) allows an executable program to be run.
