The basic syntax for using the command is:
$ bbcp [opt] user@source:/path/to/data user@destination:/path/to/store/data
Possible options include:
- -P 2
- Give a progress report every 2 seconds
- -w 2M
- TCP window size of 2MBytes
- -s 16
- Set the number of streams to 16 (default is 4)
Other options may be necessary if bbcp is not installed in a regular location on either end of the transfer. This can lead to rather complex command lines:
$ bbcp -z -T \ "ssh -x -a -oFallBackToRsh=no %I -l %U %H /home/user/Custom/bin/bbcp" \ foobar-5.4.14.tbz "firstname.lastname@example.org:foo.tbz"
