- SCP , transfer files over network
(for single file)
> scp [USER@HOST:]SOURCE_FILE_NAME USER@HOST:DESTINATION_DIRECTORY
(eg. “> scp Twilight.avi root@168.27.10.200:/home/root/movie“)
then enter destination password.

(for directory with multiple files)
> scp -r [USER@HOST:]SOURCE_DIRECTORY_NAME USER@HOST:DESTINATION_DIRECTORY
(eg. “> scp -r Movies budi@140.27.10.240:/home/budi“)
then enter destination password.

Other samples:
“> scp -r budi@140.27.10.240:/home/budi/SexyImage .” , will copies “SexyImage” directory from user “budi” at “140.27.10.240″ to our current directory. We need to provide user “budi” password.
