7 # Copies an object from Arvados instance src to instance dst.
9 # By default, arv-copy recursively copies any dependent objects
10 # necessary to make the object functional in the new instance
11 # (e.g. for a workflow, arv-copy copies the workflow,
12 # input collections, and docker images). If
13 # --no-recursive is given, arv-copy copies only the single record
14 # identified by object-uuid.
16 # The user must have files $HOME/.config/arvados/{src}.conf and
17 # $HOME/.config/arvados/{dst}.conf with valid login credentials for
18 # instances src and dst. If either of these files is not found,
19 # arv-copy will issue an error.
