I have moved (mv) a pretty large directory on my NAS (Linux based), but had to interrupt the procedure. Not being a regular Linux user, I though I could just continue and merge the rest later in.
mv /oldisk/a /newdisk
Procedure is halfway done, so rest of /oldisk/a still exists, and /newdisk/a with the already copied files is already present. I have no idea which files have been already copied. BTW, under /oldisk/a, of course, are plenty of sub directories.
What would be the best way to move / merge the remaining files to /newdisk/a ?
