RE: Escaping a variable.

[Wheeler, John]

Have you tried "dollar"

http://www.cfengine.org/docs/cfengine-Reference.html#Special%20variables

maybe
DHCP_HOSTNAME=${dollar}{HOSTNAME}  

?

Greetings.


   This sound stupid to ask, but how do I escape a $ sign?

   I have in my cf file:

      InsertLine "DHCP_HOSTNAME=${HOSTNAME}"

   And in my file being edited, I want:

     DHCP_HOSTNAME=${HOSTNAME}

   not

     DHCP_HOSTNAME=einstein

   However, \$ does not work and neither in the reference or tutorial
could I 
find some reference on how to escape the $ so that the variable is not
being 
interpreted (I search for the keyword 'escape'; maybe there is a better
keyword 
to search for?).


Best regards,
