$ cat -E marks_2015.txt
cat: illegal option -- E
usage: cat [-benstuv] [file ...]

it works with small case options
$ cat -e marks_2015.txt instead of $ cat -E marks_2015.txt

that depends on your cat version.. I've mentioned in README that GNU/Linux has been used for examples presented.. usually, I add the version of command used at start of those sections, but I've missed it for this chapter.. thanks for bringing to attention..
from manual for cat (GNU coreutils) 8.25
-e equivalent to -vE
-v, --show-nonprinting
use ^ and M- notation, except for LFD and TAB-E, --show-ends
display $ at end of each line
