CDO

With 1.5.9 you can use wildcards with the cat operators. So you might try something like this:

cdo yeardaymean -cat "temp2_echam5_amip_vary_ghg_mean_19*.nc" climate.nc

For this feature the wildcards have to be expanded in CDO and not by the Shell. Therefor single quotes must be used:

cdo yeardaymean -cat 'temp2_echam5_amip_vary_ghg_mean_19*.nc' climate.nc

Thanks for the suggestions. Are only simple wildcards allowed, or can I use more complex regular expressions. Since I'll be going over 30 years and want to exclude some of the files, a simple 19* won't work.

Hi Don,

We implemented a simple pattern matching via glob [http://en.wikipedia.org/wiki/Glob_%28programming%29]. Allowed wildcards are `*', `?' or `[ characters ]'.

Hi! I'm just starting to use CDO.

In some posts I have seen the answer "As all CDO operators with an unlimited number of input files this operator can't be combined with other operators.", but the first option appears to overcome that limitation. Is there something I am missing?
Thanks!

if you use operators like 'cat' or merge together with a wildcard your can more operators on top of the results of therese operations. But operators output cannot be used for input of 'cat' or 'merge'
