Please use perl, python, or shell to write the following scripts

(basic error handling and a simple --help instructions should be

included) Attach :



# 1. Given a test file containing lines of words such as (abc, abb,

abd, abb, etc), write a script that prints, in order of frequency, how

many times each word appears in the file.



# 2. Write a script running in an endless loop that pings an IP

(specified on the command line) periodically. If the IP goes down n

times in a row send one email message (to an address specified on the

command line) that it's down (n is specified on the command line).

Once it's available again n times in a row send an email that it's

back up. When a specific signal is sent to the script it sends and

email saying that it is shutting down and then exits.
