globus-url-copy

The globus-url-copy tool provides a command-line client for requesting transfers to, from, or between GridFTP servers. This simple command-line interface can be used manually, included in shell scripts, or invoked by applications. It is not interactive, so each invocation requests a single transfer (though that transfer might include multiple files in a directory).

The globus-url-copy tool supports many of the advanced capabilities of GridFTP servers, including:

• Grid security, including data channel(s)
• HTTP, FTP, GridFTP
• Server-to-server transfers
• Subdirectory transfers and lists of transfers
• Multiple parallel data channels
• TCP tuning parameters
• Retry parameters
• Transfer status output

The globus-url-copy command leaves configuration settings and the selection of servers up to the user. In complex systems with many servers and networks that require different tuning parameters, a wrapper that supplies these details given simple source/destination requests may be helpful. See the material covering TeraGrid's TGCP Tool in the Solutions section of this website for an example of this technique.
