Try "grep "disable\|enable" fail.log

The backslash turns the | into the "or" metacharacter, otherwise you are grepping for the literal 'disable|enable"

How to grep words in a file?
We are looking to do a remodel and move the washer and dyer into a walk in closet. I am curious of any concerns or issues regarding having a washer and dryer inside a walk in closet. Mainly, in terms of moisture. Does the washer or dryer product enough moisture in the room that we would need to include a vent? Also, does the drywall in the room need to be the same that is used in bathrooms?

Update: Clarification. 
By vent, I mean a separate vent other than the dryer vent. Something like a bathroom ceiling vent in addition to the dryer exhaust vent.
