command example before last paragraph

grep Smith | grep -v hi.txt

should be:

grep Smith editinginfo | grep -v hi.txt

explanation:
If the first grep is used without a filename arguemnt, it would use standard input, waiting for you in a new line to insert text that will be processed after pressing Ctrl-D. However this statement is supposed to be a single pipe equivalent of the previous double pipe example:

cat editinginfo | grep Smith | grep -v hi.txt

Note from the Author or Editor:
grep Smith | grep -v hi.txt

should be:

grep Smith editinginfo | grep -v hi.txt

The example
grep -color[=auto] regexp filename
should be
grep --color[=auto] regexp filename
There should be two dashes before color

Note from the Author or Editor:
The example
grep -color[=auto] regexp filename
should be
grep --color[=auto] regexp filename
There should be two dashes before color

(The heading has it correct, however).
