Paste that text to a shell script and redirect to a file and see what you get. Post your STDERR output to the forum.

what is STDERR ?

[TheWitness]

STDERR = Standard Error

In a shell script you would redirect using the "2>" redirect symbol. Otherwise, the error will just appear and the PNG file will be generated to the file. The ">" redirect will handle that portion.

So your syntax would be something like:

Code: Select all

rrdtool graph ...  > my.png

In that case STDERR will be redirected to the console

Code: Select all

rrdtool graph ... > my.png 2> my.error

In the second case STDERR will be directed to the file my.error
