Type the command:
ftp servername
File transfer protocol (ftp) is the standard cross-platform interactive tool for file transfers. Provide your username and password when prompted. The ftp session will begin.
Enter the command:
sftp servername
Secure ftp (sftp) uses an encrypted session, making it a better choice for unsecured networks.
Use the remote command copy (rcp) of BSD on trusted, secured networks only. The basic syntax is:
rcp

.
rcp file1 linuxhost2:/temp
Secure copy (scp) is an encrypted version of rcp. The transfer is sent over an encrypted Secure Shell (ssh) session. The syntax is essentially the same:
scp linuxhost2:/temp/file2 /var/tmp
Copy or synchronize entire directories, using the rsync command:
rsync -oupgrle ssh /local/directory host2:/remote/directory
Check the manual page for rsync to describe the options listed.
