htcopy: HTTP client with LCGDM extensions


htcopy - HTTP client with LCGDM extensions


htcopy [options] [source] [destination]


htcopy is a HTTP client that implements some extensions of the protocol used by the HTTP/DAV front-end of LCGDM. The command is designed to work without user interaction.

It allows to copy from local to remote, from remote to local, and it can also trigger third party copies.

It supports multiple streams for uploads and downloads, improving the performance of the transfer.


Both the source and/or the destination can be a local path or a HTTP URL. Depending on the combination, it will do an upload, a download, or trigger a third-party copy. Local copies are not supported.
