(hint: look up the Linux man page for chmod)? g) Which Unix command allows you to change the owner of a file?Explanation / Answer
a)Answer:
This is file permissions.
Explanation:
The permissions are divided into three parts:
The first three characters (rwx) are for owner permissions. The owner of the file, the user "john", can read the file, write (modify) it, and execute it, in case it is executable.
The next three characters (r-x) are for group permissions. Members of the group "staff" can read the file and execute it, in case it is executable.
The last three characters (r--) are for other (world) permissions. These are the permissions for everyone else on the system. Users other than "john" who are not members of the "staff" group can only read the file
b)Answer:
user have most control in this case because all permissions are granted for user.
c)Answer:
group has read and execute permissions but not have write permission.
d)Answer:
The user have more than one read permission.
e)Answer:
The user have write permission
f)Answer:
Linux, like UNIX, is a multi-user system and file permissions are one way the system protects against malicious tampering.
One way to gain entry when you are denied permission is to su - to root, as you learned earlier. This is because whoever knows the root password has complete access.
But switching to the superuser is not always convenient or recommended, since it is easy to make mistakes and alter important configuration files as the superuser.
That means you can specify who is allowed to read the file, write to the file, or (if it is an application instead of a text file) who can execute the file.
