    I'm not an expert on sed...but it its a one liner. But you can accomplish the same with awk.

    @phacus i agree with you.. btw i think that one liner ans works on normal terminal then why its asking me to write a shell program? ( according to question)

    @AurthurM Assuming it's an assignment, maybe they want you to create a loop?

    EDIT: Check ShellCheck always..it's a life saver

    Oneliner is any script that can fit in one line. So it's basically.. Any script :)
    to make it more correct, the script parts should not be ; separated, i.e. every command linked to another via the pipeline.

    Your sed solution is perfect for the job imo. It has the least overhead compared to other possible solutions.
