Reshaping Text With rs

Dr. Drang:

The problem was that the lists were long. One had 84 items and the other had 30. Pasting them into the message in the form I had them—one item per line—would take up too much space. Pasting them in as a comma-separated series—which I could convert them to with a simple search-and-replace—would be very hard to read. What I wanted was nicely formatted set of rows and columns that would be easy to read without taking up too much space.


After some Googling, I came across this Ask Ubuntu question, which led me to rs, an old BSD command that comes installed on macOS. The name stands for “reshape,” and it will take any row/column set of data and rearrange it into a different number of rows and columns.
