Convert hdf5 to netcdf4 in bash, R, python or NCL?

Question

Is there a quick and simple way to convert HDF5 files to netcdf(4) from the command line in bash? Alternatively a simple script that handle such a conversion automatically in R

Answer 1

NCL's ncl_convert2nc function is my go-to for this type of problem: https://www.ncl.ucar.edu/Document/Tools/ncl_convert2nc.shtml
