Do we have and operator in UNIX?

Answer 1

Use egrep:

egrep "expression1|expression2"

or

grep -E "expression1|expression2"

Answer 2

I am assuming you are in a UNIX shell.

you can you a if statement with test to find multiple results.

if [ $( $(cat mylife | grep wordone) | wc -l ) -ne 0 ] ; then
if [ $( $(cat mylife | grep wordtwo) | wc -l ) -ne 0 ] ; then DO THIS; fi
fi
