These are detailed in the man pafe for grep.

grep -v Jane project1.txt - THis will display all lines from the file project1.txt that the word 'Jane' does NOT appear on.


and
grep ' 5\..' janet.txt - this will display lines from the file janet.txt that have the string ' 5..' in. The Backslash is a special case in searching so effectively is ignored where it proceeds the . - as this is not a special character in this situation.
