THE PASTE COMMAND
====
In a previous video, we talked about the cut command which can be used to extract columns from a CSV or tabular text data file.The paste command does the exact opposite: it merges several input files on a line-by-line basis to produce a new delimited text file from them.

HOW IS IT RELATED TO OTHER COMMANDS?
----
I already mentioned in the introduction the cut command(https://yesik.it/EP22) that can be used to split delimited or fixed-width text files in individual columns that can later be merged back using the paste command. Something that can be useful when you need, for example, to re-order the columns of a table.
But the paste command identify the corresponding data based only on their physical position in the file (their "line number"). Sometimes though, we would like to merge data based on their content. If that’s your need, I suggest you take a look at the join utility(https://yesik.it/EP14) instead.
