Keep in mind that commands that report current users such as
who
use the
/var/adm/utmpx
file, whereas commands that report
login/logout
history such as
last
use the
/var/adm/wtmpx
file.
File Permissions and Ownership
File permissions determine the operations that can be performed on files and
directories along with who can perform these operations. There are two
types of file permissions:
➤
Standard, which provides basic security
➤
Extended, which expands the standard permissions
