To troubleshoot a problem I needed to copy a database's worth of files out of an ASM diskgroup and onto the filesystem. I searched around and checked help for ASMCMD assuming there was a recursive option. I found references to one in some places on the interwebs, even official Oracle references to it like Unable To Copy Directory Using ASMCMD Cp -r Command (Doc ID 829040.1) but struck out when trying to do this on 11g and 12c ASM installs.
