PRcp

PRcp is a command-line utility designed for copying files and directories between a local system and a remote host, primarily leveraging the SSH protocol for secure transfer. It aims to provide a more efficient and user-friendly alternative to traditional `scp` for certain use cases. PRcp distinguishes itself by incorporating features like progress reporting during transfers, resumable transfers for interrupted operations, and support for parallel data streams to potentially increase throughput.

The tool's primary functionality revolves around specifying a source location and a destination location. These locations can be either local paths or remote paths formatted in a way that indicates the remote host and user. For instance, a remote path might look like `user@remote_host:/path/to/file`. PRcp then establishes an SSH connection to the specified remote host and executes the file transfer operations.

One of the key advantages of PRcp is its built-in progress meter, which provides real-time feedback on the status of ongoing transfers, displaying the amount of data transferred and the estimated time remaining. This is particularly useful for large files or slow network connections. Furthermore, PRcp's ability to resume interrupted transfers means that users do not have to restart the entire copy process if the connection is dropped or the process is manually stopped. The parallel streaming feature allows PRcp to potentially utilize multiple connections simultaneously, which can significantly speed up transfers on high-bandwidth networks.
