1. Use the “ls -l” command to list the permissions of a file or directory.
2. The output of the command will show the following information:
-The type of file (i.e. – for a regular file, d for a directory).
-The file permissions (in the form of rwxrwxrwx).
-The owner of the file.
-The group the file belongs to.
-The size of the file.
-The date the file was last modified.
-The name of the file.
3. The file permissions are broken down into three sets of characters:
-The first set (rwx) represents the permissions of the file’s owner.
-The second set (rwx) represents the permissions of the group the file belongs to.
-The third set (rwx) represents the permissions of all other users.
4. Each character represents a different type of permission:
-r = read permission
-w = write permission
-x = execute permission
5. To change the permissions of a file or directory, use the “chmod” command followed by the appropriate octal code.
