No, but would be handy for systems where that's not present as an option for cp (such as the current Ubuntu 10.04 release). Just noticed that bcp isn't present in the btrfs-tools package in that release either: $ apt-cache policy btrfs-tools btrfs-tools: Installed: 0.19-8 Candidate: 0.19-8 Version table: *** 0.19-8 0 500 http://mirror.linux.org.au/ubuntu/ lucid/universe Packages 500 http://mirrors.uwa.edu.au/ubuntu/ lucid/universe Packages 100 /var/lib/dpkg/status cheers, Chris -- Chris Samuel : http://www.csamuel.org/ : Melbourne, VIC This email may come with a PGP signature as a file.
