I guess this went without response because it was an obvious shell
scripting issue, and really not about rrdtool anymore. For example, a
followup question could have been what shell you use etc etc
I was wondering though what went wrong with your example. Without
further testing my guess was the line breaks though.
If so, could be
params=`cat file`
rrdtool graph $params
might also work. The shell word splitting on that unquoted $params
should, to the best of my knowleddge, also remove any remaining line
breaks.
Anyway, glad to hear you sorted it out.
