Permissions on Unix-like systems are managed in three distinct classes. These classes are known as user, group, and others. In effect, Unix permissions are a simplified form of access control lists (ACLs).
When a new file is created on a Unix-like system, its permissions are determined from the umask of the process that created it.

Famous quotes containing the word traditional:
“Americans want action for their money. They are fascinated by its self-reproducing qualities if it’s put to work.... Gold-hoarding goes against the American grain; it fits in better with European pessimism than with America’s traditional optimism.”
—Paula Nelson (b. 1945)
