awk + how to perform OR action in awk command

I have the following file

your  Answer  = AA
your  Answer  = AB
your  Answer  = CD
your  Answer  = XY 
your  Answer  = DD

to verify all answers I run the following awk

echo "your  Answer  = AA" |  awk '/= AA/{print " passed "}'
echo "your  Answer  = AA" |  awk '/= AB/{print " passed "}'
echo "your  Answer  = AA" |  awk '/= CD/{print " passed "}'
echo "your  Answer  = AA" |  awk '/= XY/{print " passed "}'
echo "your  Answer  = AA" |  awk '/= DD/{print " passed "}'

My question: How to do the same on one awk command in ple开发者_如何学Cace to run 5 awk command?

Like

echo "your Answer = AA" | awk '/= AA|AB|CD|XY|DD/{print " passed "}'

You're close: you just need to put the alternates in a group so the equal sign is always there:

echo "your Answer = AA" | awk '/= (AA|AB|CD|XY|DD)/ {print " passed "}'

awk -F"=" '$2~/A[AB]|[CD]D|XY/{print "passed"}' file

or(echo "your  Answer  = AA",echo "your  Answer  = AA") | awk '/= AA/{print " passed "}'

Try something like this.
