Problem
1. Create an alias named rm that always deletes files recursively and forcibly. How can you execute the original rm command without unaliasing it and without using an absolute pathname?
2. How do you repeat the last command in
(i) Korn,
(ii) Bash?
3. How will you configure the history facility to store the last 200 commands in memory in (i) Korn, (ii) Bash?
