linemerging

A: In file operations, "round-robin" refers to the method of merging multiple files such that lines from each file are interleaved in turn. For instance, when merging three files, the first line from the first file is followed by the first line from the second, then the first line from the third file, before moving to the second line of each file, and so on. Q2: How can paste be used to perform this operation? A: The paste command is typically used to combine lines from files side by side, but it can also be employed to merge lines sequentially from multiple files in a round-robin manner. This is achieved by using the --serial option (or -s) which instead of pasting lines horizontally, pastes them vertically.
