Hi Uwe, Ralf and all,

In case of I don't need to append command to history global attribute. How to do that?

Hi!

you can use setgatt to overwrite the history attribute:

cdo setgatt,history,test in.nc out.nc
produces 
// global attributes:
                :history = "test" ;

But there is no commandline option or environment variable to prevent CDO from adding its operatons to the history. You have to prefix your CDO calls with setgatt.

Ralf

I would like to have such an not-append option, especially for very long -select,name=varname f1 f2 ... f99999 history entries, which are annoying most of the time. Or maybe an option to shorten such history entries? Rewriting the history as suggested seems to be more complicated to me.

Thanks for consideration,
Chris

The CDO option --no_history disables appending the history attribute:

cdo --no_history -select,...  infile outfile

Thank you very much! I could not find this option in the most recent cdo docu.

Can we remove part of the history in a quick way?

history = "history1; history2";

=>

history = "history2";

Thanks,
