Understanding Filesystem Permissions


Symbolic Representation

The first character indicates the file type và is not related lớn permissions. The remaining nine characters are in three sets, each representing a class of permissions as three characters. The first set represents the user class. The second set represents the group class. The third set represents the others class.

Each of the three characters represent the read, write, & execute permissions:

r if reading is permitted, - if it is not.w if writing is permitted, - if it is not.x if execution is permitted, - if it is not.

The following are some examples of symbolic notation:

-rwxr-xr-x a regular tệp tin whose user class has full permissions and whose group và others classes have only the read and execute permissions.crw-rw-r-- a character special file whose user & group classes have the read and write permissions and whose others class has only the read permission.dr-x------ a directory whose user class has read và execute permissions & whose group and others classes have no permissions.Numeric Representation

Another method for representing permissions is an octal (base-8) notation as shown. This notation consists of at least three digits. Each of the three rightmost digits represents a different component of the permissions: user, group, and others.

Each of these digits is the sum of its component bits As a result, specific bits add to the sum as it is represented by a numeral:

The read bit adds 4 lớn its total (in binary 100),The write bit adds 2 khổng lồ its total (in binary 010), andThe execute bit adds 1 khổng lồ its total (in binary 001).

These values never produce ambiguous combinations. Each sum represents a specific phối of permissions. More technically, this is an octal representation of a bit field – each bit references a separate permission, and grouping 3 bits at a time in octal corresponds to lớn grouping these permissions by user, group, and others.
