[rrd-users] Re: Argument List too long?

[Kant, D (Dave)]

Hi Tobias,

I'm not sure I understand the correct format for invoking rrdtool's pipe mode.
Do you mean something like this?

 rrdtool graph < my_long_arg_list.txt > out

where my_long_arg_list.txt would look something like this?
 
[]cat my_long_arg_list.txt
site_disk_HMW6dFGqY4.png -t 'Used Disk Storage' -s -3m -w500 -h125 -l 0 \
DEF:A=A_multidisk.rrd:Used:MAX \
DEF:B=B_multidisk.rrd:Used:MAX \
...

Dave

Hi Dave,

if you use the rrdtool pipe mode then the limitations of your shell
will not apply!
