- Change rclone/fs interfaces to accept context.Context - Update interface implementations to use context.Context - Change top level usage to propagate context to lover level functions Context propagation is needed for stopping transfers and passing other request-scoped values.

Use: "copy source:path dest:path",

Short: `Copy files from source to dest, skipping already copied`,
|
|
Long: `
|
|
Copy the source to the destination. Doesn't transfer
|
|
unchanged files, testing by size and modification time or
|
|
MD5SUM. Doesn't delete files from the destination.
|
|
|
|
Note that it is always the contents of the directory that is synced,
|
|
not the directory so when source:path is a directory, it's the
|
|
contents of source:path that are copied, not the directory name and
|
|
contents.
|
|
|
|
If dest:path doesn't exist, it is created and the source:path contents
|
|
go there.
|
|
|
|
For example
|
|
|
|
rclone copy source:sourcepath dest:destpath
|
|
|
|
Let's say there are two files in sourcepath
|
|
|
|
sourcepath/one.txt
|
|
sourcepath/two.txt
|
|
|
|
This copies them to
|
|
|
|
destpath/one.txt
|
|
destpath/two.txt
|
|
|
|
Not to
|
|
|
|
destpath/sourcepath/one.txt
|
|
destpath/sourcepath/two.txt
|
|
|
|
If you are familiar with ` + "`rsync`" + `, rclone always works as if you had
|
|
written a trailing / - meaning "copy the contents of this directory".
|
|
This applies to all commands and whether you are talking about the
|
|
source or destination.
|
|
|
|
See the [--no-traverse](/docs/#no-traverse) option for controlling
|
|
whether rclone lists the destination directory or not. Supplying this
|
|
option when copying a small number of files into a large destination
|
|
can speed transfers up greatly.
|
|
|
|
For example, if you have many files in /path/to/src but only a few of
|
|
them change every day, you can to copy all the files which have
|
|
changed recently very efficiently like this:
|
|
|
|
rclone copy --max-age 24h --no-traverse /path/to/src remote:
|
|
|
|
**Note**: Use the ` + "`-P`" + `/` + "`--progress`" + ` flag to view real-time transfer statistics
|
|
`,
