Question

Which of the following is not a content of inode?

(a) file type

(b) file permission

(c) file size and links

(d) file name

I have been asked this question in an international level competition.

This interesting question is from Advanced File Handling Commands in chapter Customizing the Environment & More File Attributes of Unix

Answer 1

Right choice is (d) file name

For explanation: Every file is associated with a table that contains all the necessary possible information we need to know about a file. This table contains the following attributes of a file:

•    file type

•    file permissions

•    an array of pointers that keeps track of all disk blocks used by the file

•    file size and links

•    The UID of owner and GID of a group owner

•    Date and time of:

o    Last access

o    Last modification

o    Last change of inode
