Now I spot my next problem which I vaguely recall I never worked
around first time I looked at it.
Looking back at my scripts, I previously used rrdcgi because ... I
have many different graph variants, and many of them have the
definition built using conditionals and loops. Up until now, I've
been adding bits to a text file, and then feeding the text file
through rrdcgi - I'm struggling to do the same with rrdtool graph.
In effect, I need to do something like :
rrdtool graph <file> `cat ${Tempfile}`
which doesn't work - and I'm sure this will be something trivial !
