[rrd-users] extract command line options used to create an RRD file (SOLVED)

[a.smith at ukgrid.net]

Solved, or worked around at least. I got the script working by  
changing two things, firstly the data I export to file in the export  
step I changed from $create to @create, secondly on the import side I  
dumped the use of the perl module RRDs cos I couldnt figure out how to  
feed the create options into it properly, and instead put in back  
quotes the unix command
`rrdtool create "$dir/$basename" @create`;

The arguements I am passing from @create are like:

--step 300 DS:ups_load_output2:GAUGE:600:0:100 RRA:AVERAGE:0.5:1:500  
RRA:AVERAGE:0.5:6:700 RRA:AVERAGE:0.5:24:775 RRA:AVERAGE:0.5:1:26280  
RRA:AVERAGE:0.5:288:797 RRA:MIN:0.5:6:700 RRA:MIN:0.5:24:775  
RRA:MIN:0.5:1:26280 RRA:MIN:0.5:288:797 RRA:MAX:0.5:1:500  
RRA:MAX:0.5:6:700 RRA:MAX:0.5:24:775 RRA:MAX:0.5:1:26280  
RRA:MAX:0.5:288:797 RRA:LAST:0.5:6:700 RRA:LAST:0.5:24:775  
RRA:LAST:0.5:1:26280 RRA:LAST:0.5:288:797

If anyone can tell me how to correctly pass this to RRDs::create Id be  
interested to know, but I do already have a working script :)

thanks Andy.
