Correct Option: C

AI Explanation

To answer this question, you need to understand the command used to find the block size on a Unix file system.

Option A) blksz - This option is incorrect because there is no such command "blksz" to find the block size on a Unix file system.

Option B) szblk - This option is incorrect because there is no such command "szblk" to find the block size on a Unix file system.

Option C) cmchk - This option is correct because the "cmchk" command is used to find the block size on a Unix file system. This command can be used to check the block size of a file system or a device.

Option D) chksz - This option is incorrect because there is no such command "chksz" to find the block size on a Unix file system.

The correct answer is Option C) cmchk. This option is correct because the "cmchk" command is used to find the block size on a Unix file system.

Correct Option: B

The minimum number of links for any directory file are 2.

  1. True

  2. False


Correct Option: B

AI Explanation

To answer this question, we need to understand the concept of directory files and their links.

In a file system, a directory file is used to store information about other files and directories. Each directory file contains a list of links, which are references to other files or directories.

The minimum number of links for any directory file is actually 2. The first link is a reference to itself (".") and the second link is a reference to its parent directory (".."). These links are necessary for the directory file to maintain its own location and hierarchy within the file system.

Therefore, the correct answer is:

B) False - The minimum number of links for any directory file is 2, not 0.

Sticky bit can only be set for binary executable file. (Tie Breaker)

  1. True

  2. False


Correct Option: B

Which UNIX command is used to write in-core super block and inode table information to the disk?

  1. write

  2. sync

  3. insync

  4. write_core


Correct Option: B

AI Explanation

To answer this question, you need to understand the purpose of the different UNIX commands related to writing data to disk.

Option A) write - This option is incorrect because the "write" command is used to send messages to other users or terminals, not to write data to the disk.

Option B) sync - This option is correct because the "sync" command is used to flush file system buffers and write in-core super block and inode table information to the disk. It ensures that all pending disk writes are completed and that the file system is synchronized.

Option C) insync - This option is incorrect because there is no "insync" command in UNIX. It is not a valid command.

Option D) write_core - This option is incorrect because there is no "write_core" command in UNIX. It is not a valid command.

The correct answer is B) sync. This option is correct because the "sync" command is used to write in-core super block and inode table information to the disk, ensuring that all pending disk writes are completed and that the file system is synchronized.
