File Copying using hkexcp
--
hkexcp is a symlink to hkexsh, and the binary checks its own filename to determine whether it is being invoked in 'shell' or 'copy' mode. Refer to the '-h' output for differences in accepted options.
General remote syntax is: user@server:[/]src-or-dest-path
If no leading / is specified in src-or-dest-path, it is assumed to be relative to $HOME of the remote user.
File operations are all performed as the remote user, so account permissions apply as expected.
Local (client) to remote (server) copy:
* cd hkexsh && ./hkexcp fileA /some/where/fileB /some/where/else/dirC joebloggs@host-or-ip:/remoteDir
Remote (server) to local (client) copy:
* cd hekxsh && ./hkexcp joebloggs@host-or-ip:/remoteDirOrFile /some/where/local/Dir
NOTE: Renaming while copying is NOT supported (ie., like cp's 'cp /foo/bar/fileA ./fileB). Put another way, the destination (whether local or remote) is ALWAYS a dir.
hkexcp uses tar with gzip compression (ala a 'tarpipe') under the hood, sending tar data over the hkex encrypted channel. Use the -d flag on client or server to see the generated tar commandlines if you're curious.
