File permissions when saving a netcdf file

[vrx-]

Hi,
I was wondering if there is a way to manually set file permissions when saving a NetCDF file with xarray. There is a code I run in a remote server that generates netcdf files. Weird thing is, the files end up having different sets of permissions. Most likely this has more to do with random blips in the filesystem than xarray itself, but if there is a way to force a specific set of permissions this would help in code that generates files for sharing. I know I can solve this easily with a bash script after the deed is done, but I thought to ask.
Here is an example of what I mean:

not that I'm aware of. However, you can use the builtin os or pathlib modules to do the chmod immediately after writing:

ds.to_netcdf(path)
path.chmod(0o644)  # pathlib
os.chmod(path, 0o644)
