hobbes@metalbaby:~/e2-scratch$ cat faces_mre.txt (◕‿◕) (︺︹︺) hobbes@metalbaby:~/e2-scratch$ uniq -c faces_mre.txt 2 (◕‿◕) Here's some background info: hobbes@metalbaby:~/e2-scratch$ od -x faces_mre.txt 0000000 e228 9597 80e2 e2bf 9597 0a29 ef28 bab8 0000020 b8ef efb9 bab8 0a29 0000030 hobbes@metalbaby:~/e2-scratch$ locale LANG=en_US.UTF-8 LANGUAGE= LC_CTYPE="en_US.UTF-8" LC_NUMERIC="en_US.UTF-8" LC_TIME="en_US.UTF-8" LC_COLLATE="en_US.UTF-8" LC_MONETARY="en_US.UTF-8" LC_MESSAGES="en_US.UTF-8" LC_PAPER="en_US.UTF-8" LC_NAME="en_US.UTF-8" LC_ADDRESS="en_US.UTF-8" LC_TELEPHONE="en_US.UTF-8" LC_MEASUREMENT="en_US.UTF-8" LC_IDENTIFICATION="en_US.UTF-8" LC_ALL= hobbes@metalbaby:~/e2-scratch$ uniq --version uniq (GNU coreutils) 8.26 Copyright (C) 2016 Free Software Foundation, Inc.
