Hello,
Cross-filesystem copying seems to have been broken in the latest coreutils
release on macOS. 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?
Thanks in advance,
Sudhip Nashi
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,
