 I don't think I understand your intent, but in order to match
 lines other than ones composed solely of =, try /^[^=]+$/

 To match a location that does not contain a specific string, you
 can try:

    /(?!foo)/

 this regular expression will match a location that does not
 contain the sequence "foo".  Beware!  Note that I'm writing
 "location", not "string".  This matches:

    "foo" =~ /(?!foo)/ )/     # anything not followed by foo, match

 This also matches:

    "foobar" =~ /(?!bar)/     # anything not followed by bar, match

 You have to anchor it somehow:

    "foobar" =~ /foo(?!bar)/  # "foo" not followed by "bar", no match
