The df utility displays all mounted filesystems along with information about each. Use the df utility with the –h (human-readable) option to answer the following questions.

a. How many filesystems are mounted on the local system?
b. Which filesystem stores your home directory?
c. Assuming your answer to exercise 4a is two or more, attempt to create a
hard link to a file on another filesystem. What error message is displayed?
What happens when you attempt to create a symbolic link to the file
instead?

Following are sample answers to these questions. Your answers will be dif-

ferent because your filesystems are different.

a. six; b. /dev/hda4; c. ln: creating hard link '/tmp/xxx' to 'xxx': Invalid

cross-device link. No problem creating a cross-device symbolic link.
