You can also use awk for this:

echo "Hello hi" | awk '/Hello|Hi/'
Hello hi

You can make use of egrep, which per definition is the same as grep -E. It interprets the patterns as extended regular expressions, so that grep -E "hello|hi" means: "grep either hello or hi".

So both of these should work:

echo "Hello hi" | egrep -i "hello|hi"  # as you are using -i, no need to low/upper case

echo "Hello hi" | grep -Ei "hello|hi"

In case of doubt, you can always check your man grep and see what they explain there. As I do not have access to any Solaris server, I cannot test myself.
