how to write script for these
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
thanx
