Help to chain sinfon with cat operator in CDO
Added by Kendy Silvério over 5 years ago
Dear All,
I am applying cdo for the attached file to extract file.txt.
For that, I use cdo infon ecmwf_1-7_DJF_ev.nc|grep -e anom >ecmwf_1-7_anom.txt, then I use
cat ecmwf_1-7_anom.txt|tr -s " "|cut -d ' ' -f10 |tail -n +60 |head -n -31 >ecmwf_1-7_an.txt and it works well.
However, I would like to chain the above syntaxis in one commandline, which I am planing to use in bash script.
Can anyone please help me?
I apologise if I am not clear. But I would be happy to answer any questions if you have any.
Thank you so much for your help in advance.

Hi Kendy,
you can pipe the output directly to the tr command, no redirection, no ecmwf_1-7_anom.txt!
cdo infon ecmwf_1-7_DJF_ev.nc | grep -e anom | tr -s " "| cut -d ' ' -f10 | tail -n +60 | head -n -31 > ecmwf_1-7_an.txt
