UNIX Shell Scripting Bourne loop Question programming homework help

Description:

Write a shell script (to run on the Bourne shell) that runs an infinite loop to monitor the creation and removal of .pdf or .PDF files under the current directory. Every 3 seconds it should display a list of those filenames created or removed after the previous display. Without loss of practical significance of this utility, we can assume that the time interval between creation of .PDF or .pdf file and removal of a .PDF or .pdf file is over 3 seconds, which means that it’s unnecessary for your script to handle the situation where creation of a file is followed by immediate removal of a file. (Hint: research the cmp and comm commands.) Your script for this task must be named tasktwo.sh

The following is a sample output of the script (It is OK that the script leaves behind a temporary file when it is finally interrupted):

No pdf files have been created or removed in the last 3 seconds.

No pdf files have been created or removed in the last 3 seconds.

The following pdf file(s) have been created in the last 3 seconds:

a3.pdf   a4.pdf   a5.pdf

The following pdf file(s) have been removed in the last 3 seconds:

a4.pdf   a5.pdf

No pdf files have been created or removed in the last 3 seconds.

No pdf files have been created or removed in the last 3 seconds.
