Title: Syntax in example of generating MD5 in Linux is incorrect

Using echo(1) without -n gives a trailing newline. This is why the result in the MD5 example for "Mac OS" was different than the result in the MD5 example for "Linux."

Realized this issue via a [forum post comparing output of Perl's Digest::MD5::md5_hex()](http://objectmix.com/perl/304708-why-doesnt-digest-md5-md5_hex-match-gnu-md5sum.html):

$ echo joe@t3ch.com | od -c
0000000 j o e @ t 3 c h . c o m \n
0000015
$ echo -n joe@t3ch.com | od -c
0000000 j o e @ t 3 c h . c o m
0000014
