Read the man page for setfacl

Pay attention to the Examples

It should become apparent what the difference is.

chmod only caters for permissions based on owner group all:

-rwx------ = read,write, and execute for owner only:

Code:

chmod 700 file

-rwxrwx--- = read,write, and execute for owner and 1 specific group:

Code:

chmod 770 file

setfacl allows for much greater control over who has access to a specific file or folder.

You can grant an additional user read access to a file:

Code:

setfacl -m u:lisa:r file
