Problem
1. You have just used the command tar -cvf /dev/fd0 *.sh. How will you repeat the command to use the .pl files this time in
(i) Korn,
(ii) Bash?
2. In the Korn shell, the command r ca runs from the history list
(i) the last command having ca embedded,
(ii) the first command beginning with ca,
(iii) the last command beginning with ca,
(iv) all commands beginning with ca.
