Escaped to multi-line format

An often-followed convention when reproducing shell scripts online is escaping carriage returns, using the backslash character, in order to render single very long continous lines into multiple lines for readability. For example, the following simple script, which concatenates a lot of files into one file named "all.files":

#!/bin/sh

cat one.file two.file three.file four.file five.file six.file seven.file eight.file > all.files

Could be rendered like this:

#!/bin/sh

cat one.file two.file three.file \
four.file five.file six.file \
seven.file eight.file \
> all.files
