Running a command like ‘cp /usr/bin/clear /tmp/test’ appears to return successfully, but if one analyzes /tmp/test, it’s filled with NULL characters. However, copying works fine when the source and destination file are on the same filesystem. Do you know what might be causing this?

What are the source and dest file system types?
Could you send the output of `sudo dtruss cp /usr/bin/clear /tmp/test`?
I suspect SEEK_DATA may have issues on nacOS,
as usage of that is new in coreutils 9.0.

thanks,
