(tramp-rclone-do-copy-or-rename-file OP FILENAME NEWNAME &optional OK-IF-ALREADY-EXISTS KEEP-DATE PRESERVE-UID-GID PRESERVE-EXTENDED-ATTRIBUTES)

Documentation

Copy or rename a remote file.

OP must be copy or rename and indicates the operation to perform. FILENAME specifies the file to copy or rename, NEWNAME is the name of the new file (for copy) or the new name of the file (for rename). OK-IF-ALREADY-EXISTS means don't barf if NEWNAME exists already. KEEP-DATE means to make sure that NEWNAME has the same timestamp as FILENAME. PRESERVE-UID-GID, when non-nil, instructs to keep the uid and gid if both files are on the same host. PRESERVE-EXTENDED-ATTRIBUTES is ignored.

This function is invoked by tramp-rclone-handle-copy-file and tramp-rclone-handle-rename-file. It is an error if OP is neither of copy and rename. FILENAME and NEWNAME must be absolute file names.
