If only!  I usually end up using a generous portion of trial-and-error
to find something that works.  Sometimes you have to escape the escape
characters that will be used further down the chain.


The most egregious example of multiple escapgin in my configs at the
moment looks like this:

  check_nrpe!-c CheckFile -a MinWarn=0 filter-written=\\<8d
file=D:\\\\directory\\\\subdirectory\\\\\\*.\\*


In another example, I set the $USER10$ macro in resource.cfg to
contain a single semi-colon like so:

  #  Set this macro to contain a semi-colon so we can use it as a
command separator.
  $USER10$=;

And that's just so that it can then be used in an action_url directive
pointing to a DRRAW graph like so:

  action_url
http://nagios/drraw-pnp/index.cgi?Mode=view&#59$USER10$Graph=1281540323.16309

Of course the &#59 also translates to a semi-colon.  I can't remember
why I have both in there, but it works!
