shell script for using CDO codes
Added by nazanin tavakoli almost 4 years ago
Hello,
I am using the windows batch file of cygwin46 on windows 10 for my CDO code, but unfortunately, It is really hard for me to code in a windows batch file, because my codes are too long. Could anybody recommend me a shell script for using CDO in windows?

Try writing the script in bash (https://mywiki.wooledge.org/BashGuide) and run it from a cygwin terminal. It is either that, or using windows powershell to call the command from cygwin. I do not recommend the second option, unless you really want to learn powershell.

Installing a Linux terminal doesn't damage my system? I have Ubuntu 18.4 in my virtual box, too. But I am really comfortable using windows. If installing a Linux terminal doesn't damage my system, I will try it

What is the "Windows batch file of cygwin"? I assumed that you already had cygwin installed on your PC. If not, you should instead install windows subsystem for linux (WSL1) and then install cdo using the anaconda distribution (https://code.mpimet.mpg.de/projects/cdo/wiki/Win32). Cygwin is a linux emulator that runs under windows. It probably runs faster than than running under (WSL1), but cygwin cdo has a bug that might prevent opening netcdf4 and netcdf 4 classic file types.

I have installed the terminal of ubuntu 18.04 on my windows. Does it have bugs with netcdf4? I am working on netcdf4
RE: shell script for using CDO codes - Added by Brendan DeTracey almost 4 years ago
I have used WSL1 Ubuntu 18.04 and cdo without problems. The only problem is that the Ubuntu 18.04 version of cdo will be old. That is why I suggested installing anaconda and using its conda package manager to install cdo. This will give you the most recent cdo version. If you do not care about age, install cdo from your Ubuntu terminal:
$ sudo apt install cdo

Thank you very much. Now, for running my cdo code, I use a bash script like the one I have sent it here, AND for running it I use sh cdoC.txt. The terminal shows me this:
cdo copy/selall : UNCHANGED_RECORD=0
cdo copy/selall : cdiGribDataScanningMode=0; lcopy=0
Is it s.th important?

I don't know. Do the output values look correct? You could try running the same command with the verbose option cdo -v ...

Hi again,
I have a serious problem. I want to resample my data with the following code in a bash script (windows subsystem for Linux).
#!/etc/bash
cdo genbil,gridfile1.txt clay0_5.nc Tbil.nc
cdo remap,gridfile1.txt,Tbil.nc clay0_5.nc clay0_5bil.nc
cdo genbic,gridfile1.txt clay0_5.nc Tbic.nc
cdo remap,gridfile1.txt,Tbic.nc clay0_5.nc clay0_5bic.nc
cdo gennn,gridfile1.txt clay0_5.nc Tnn.nc
cdo remap,gridfile1.txt,Tnn.nc clay0_5.nc clay0_5nn.nc
cdo gendis,gridfile1.txt clay0_5.nc Tdis.nc
cdo remap,gridfile1.txt,Tbdis.nc clay0_5.nc clay0_5dis.nc
but, It shows me this error:
cdo genbil (Abort): Open failed on gridfile1.txt!
cdo remap (Abort): Open failed on gridfile1.txt!
: not found: code.txt:
cdo genbic (Abort): Open failed on gridfile1.txt!

could you please help me? I really need help.
I have sent my code, data, and gridfile1.txt here.

You are getting close, my friend. First, re-read section 1.4.2.4 (https://code.mpimet.mpg.de/projects/cdo/embedded/index.html#x1-210001.4.2) paying close attention to the table. Your lonlat grid file is incorrect. You are missing nvertex
, xbounds
and ybounds
i.e. the grid cell vertices. Second, the command line should be $ cdo remap,Tbil.nc,gridfile1.txt clay0_5.nc clay0_5bil.nc
, i.e. the weight file is the first argument to the remap command (https://code.mpimet.mpg.de/projects/cdo/embedded/index.html#x1-6650002.12.8).
RE: shell script for using CDO codes - Added by nazanin tavakoli almost 4 years ago
I have changed my lonlat gridfile, and also my code as you have mentioned in previous massage like below:
gridfile:
gridtype = lonlat
gridsize = 359253
xname = longitude
xlongname = longitude
xunits = degrees_east
yname = latitude
ylongname = latitude
yunits = degrees_north
xsize = 669
ysize = 537
xfirst = 140.6905
xinc = 0.021
yfirst = -39.2369
yinc = 0.021
nvertex=2
xbounds=1338
ybounds=1074
here is my code:
#!/usr/bin/env bash
$cdo genbil,gridfile1.txt clay0_5.nc Tbil.nc
$cdo remap,gridfile1.txt,Tbil.nc clay0_5.nc clay0_5bil.nc
$cdo genbic,gridfile1.txt clay0_5.nc Tbic.nc
$cdo remap,gridfile1.txt,Tbic.nc clay0_5.nc clay0_5bic.nc
$cdo gennn,gridfile1.txt clay0_5.nc Tnn.nc
$cdo remap,gridfile1.txt,Tnn.nc clay0_5.nc clay0_5nn.nc
$cdo gendis,gridfile1.txt clay0_5.nc Tdis.nc
$cdo remap,gridfile1.txt,Tbdis.nc clay0_5.nc clay0_5dis.nc
but I have this error:

I get strange error like this

I think you use windows style line endings in your text file, which may confuse the unix environment.
- windows line end:
\r\n
- unix line end:
\n
you can convert the code.txt file to unix with the command dos2unix
. there should be a binary package with the same name provided by your package manager.

I have used the command dos2unix in ubuntu 18 in the windows subsystem (dos2unix -n code.txt code_cdo.txt) but It shows me this error:

remove the '$' of $cdo
