Package rs

https://man.openbsd.org/rs.1

rs reads the standard input, interpreting each line as a row of blank-
separated entries in an array, transforms the array according to the
options, and writes it on the standard output. Numerous options control
input, reshaping and output processing; the simplest usage example is
"ls -1 | rs", which outputs the same (on an 80-column terminal) as the
modern "ls" with no "-1" argument.
