Subject: Need regex to match "^\n"

Hi:

I am looking for a regex that will match a line with a single
carrot:

 line = "^\n"

However, the obvious does not seem to work:


irb(main):001:0> line1 = "^\n"
=> "^\n"
irb(main):002:0> line2 = "fred"
=> "fred"
irb(main):003:0> /^^/ =~ line1
=> 0
irb(main):004:0> /^^/ =~ line2
=> 0

Using /^\^/ gives an error.

What I have done to temporarily solve the problem is to use:

irb(main):012:0> /^[ ^]/ =~ line1.strip
=> 0
irb(main):011:0> /^[ ^]/ =~ line2.strip
=> nil

Does anyone know how to match '^' at the beginning of a line?
