[rrd-users] problem with 'cat file | rrdtool - ' syntax

[unicsonline]

Hello

I have a little problem to change rrdtool graphing mode from normal to pipe:

For example my test file contains:

rrdtool graph lpar.png --imgformat PNG \
--title "test" \
--width 800 --height=400 \
DEF:v1_PhysicalCPU=lpar.rrd:
PhysicalCPU:AVERAGE:step=300:end=start+24h:start=midnight  \
CDEF:r1_PhysicalCPU=v1_PhysicalCPU \
VDEF:m1_PhysicalCPU=r1_PhysicalCPU,MINIMUM \
VDEF:M1_PhysicalCPU=r1_PhysicalCPU,MAXIMUM \
VDEF:A1_PhysicalCPU=r1_PhysicalCPU,AVERAGE \
VDEF:l1_PhysicalCPU=r1_PhysicalCPU,LAST \
CDEF:y1_PhysicalCPU=r1_PhysicalCPU,0,+ \
LINE1:y1_PhysicalCPU#00FFFF:"PhysicalCPU............................": \
GPRINT:m1_PhysicalCPU:"min\: %10.2lf" \
GPRINT:M1_PhysicalCPU:"  max\: %10.2lf" \
GPRINT:A1_PhysicalCPU:"  avg\: %10.2lf" \
GPRINT:l1_PhysicalCPU:"  last\: %10.2lf\l"


and if I lauch this simple script, no problem, I get graph

Now how to generate same graph, but with a pipe syntax, like 'cat file |
rrdtool - ' or 'rrdtool - < file' ?

I have tried to just remove 'rrdtool' from the file listed upper, and then
perform a cat file | rrdtool - , and the result is:

ERROR: Could not make sense out of '\'
ERROR: unknown function '--title'
ERROR: unknown function '--width'
ERROR: unknown function

ERROR: unknown function 'GPRINT:A1_PhysicalCPU:  avg\: %10.2lf'
ERROR: unknown function 'GPRINT:l1_PhysicalCPU:  last\: %10.2lf\l'

If I remove the '\' at end of each lines and rerun, the result is:

0x0
OK u:0.00 s:0.00 r:0.00

ERROR: unknown function '--width'
