Boy, that does not do what I expected based on the documentation, and having -t and -T invert args didn't help :) But the little test below seems to do the right thing. I'll send a new patch using cp -T, thanks! #!/bin/bash rm -rf /tmp/d mkdir -p /tmp/d/a/e/f #mkdir -p /tmp/d/b cp -aT /tmp/d/a /tmp/d/b find /tmp/d echo rm -rf /tmp/d mkdir -p /tmp/d/a/e/f mkdir -p /tmp/d/b cp -aT /tmp/d/a /tmp/d/b find /tmp/d echo rm -rf /tmp/d mkdir -p /tmp/d/a touch /tmp/d/a/f #mkdir -p /tmp/d/b cp -aT /tmp/d/a /tmp/d/b find /tmp/d echo rm -rf /tmp/d mkdir -p /tmp/d/a touch /tmp/d/a/f ln -s /tmp/d/a/f /tmp/d/a/g ln /tmp/d/a/f /tmp/d/a/h mkdir -p /tmp/d/b cp -aT /tmp/d/a /tmp/d/b find /tmp/d ls -li /tmp/d/b -serge ------------------------------------------------------------------------------ Keep yourself connected to Go Parallel: BUILD Helping you discover the best ways to construct your parallel projects. http://goparallel.sourceforge.net _______________________________________________ Lxc-devel mailing list Lxc-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/lxc-devel
