Is it possible to run
cp again after it was aborted and make it start where it ended last time (not overwrite data that's already copied, only copy what's still left)?
It's cases like this that have taught me to use
rsync from the start. However in your case, you can use rsync now. It will only copy new data across, including if
cp stopped half way through a big file.
You can use it just like cp, like this:
rsync --append /where/your/copying/from /where/you/want/to/copy
Use the -u switch, and see the cp man page.
In case the aborted
cp was a recursive copy, you might want to resume with rsync including the option
Aborted copy command:
cp -r source-directory destination-directory
Let us assume that
destination-directory already existed, so that this copy command created a directory named
destination-directory. This can be resumed via:
rsync --recursive --append source-directory destination-directory
Note that trailing slashes have a precise meaning in rsync path options.
In this case, the copy command could have gotten the argument
source-directory/, it does not make a difference. In the rsync command, however, it must be
source-directory without trailing slash.
rsync is a great tool also: man page at -> http://www.manpagez.com/man/1/rsync/
