Could xrdcp overwrite a file which already exists? Because now
"xrdcp -f " will create a new file if the file already exists. It
caused a lot of problem for us. Because some of us used "xrdcp -f" to
rerun failed jobs, it created more than one replication for some
files(one good file and the others are bad files). When reading these
files, xrootd randomly select one replication to read. The result is
that many bad files are read.
So could xrdcp have an option to overwrite the old file instead of
creating a new replication?
