Using OR Operator

Sample file,

cat fruits.txt
yellow bananas
green apples
red oranges
red apples

Using OR operator in grep search. Note you need a somewhat current version of grep (you are out of luck with Solaris),

grep 'apples\|oranges' fruits.txt
green apples
red oranges
red apples

Look up if time permits how to do this using quotes to handle spaces or special characters....

Hmm, maybe all I need to do is escape any special characters and spaces probably work as is.
