Question

Introduction to Linux/Unix

5. Print to the terminal the contents of foo.txt, selecting only those lines with the word "foo" as a whole word
In other words, "foo" must NOT appear as part of another string, like "foobbbbbbbb".
There is an option for grep that tells it to only match the string when it appears as a word, not as part of a bigger string
Check the man page for grep to find this option
Don't call the man page from within your shell script.

What's the command?
