rs reads its input into an array of rows and columns, applies a specified transformation to the array, and writes it out with the specified number of rows and columns. It can be used to do column formatting and tidying of text, to transpose rows to columns and columns to rows (word-by-word, not character-by-character), and as a wrapper around line-oriented tools to let them handle multiline data. Rs is often distributed together with jot and lam, sometimes under the name bsd-utils.
