Recently rs has adopted a habit of damaging data in long lines of input. This can easily be tested: # jot -s\ -b 01234567 1000 | rs 0 1 | grep -vxF 01234567 012345 67 012 34567 012345 67 012 34567 012345 67 012 34567 The jot command prints the string 01234567 a thousand times in a single row. The rs command is supposed to generate an automatic(0) number of rows with 1 column per row. I.e. every word stands in its own line. The grep filters all intact words, so everything that is printed, was damaged by rs. This has the look of a repetitive pattern to me, probably this happens at a fixed buffer boundary. > uname -a FreeBSD mobileKamikaze.norad 8.1-STABLE FreeBSD 8.1-STABLE #0: Mon Sep 6 17:08:51 CEST 2010 root@mobileKamikaze.norad:/usr/obj/HP6510b-8/amd64/usr/src/sys/HP6510b-8 amd64 -- A: Because it fouls the order in which people normally read text.
