1. SCP - Secure Copy Protocol

  This utility is handy for transferring files from one Linux system directly
  to another using ssh security with authentication. Unline rcp, scp will ask 
  for passwords or passphrases if they are needed for authentication.

  Upload (syntax):
  scp  @:

  Upload (example):
  scp index.html username@www.companyname.com:/usr/httpd/virtual/www.companyname.com/html

  Download (syntax):
  scp @: 

  Download (example):
  scp -r username@www.companyname.com:/usr/httpd/virtual/www.companyname.com/html  /mylocalpc/mywebsitedirectory

  Useful options:
  -p preserve timestamp and info       -B batch mode
  -r recursive copy                    -C compression
  -v verbose mode                      

2. RZSZ - XMODEM, YMODEM, ZMODEM file transfer

  This utility is handy for transferring files from a Microsoft Windows system
  to or from a Linux system over tcp/ip.  It is also useful to transfer files
  to or from Linux systems using a serial cable and minicom.  The RZSZ package
  includes (sx, sb, sz, rx, rb, rz) commands.

3. ZSSH - File transfer using Secure Shell and RZSZ

  zssh (Zmodem SSH) is a program for interactively transferring files to and 
  from a remote machine while using ssh. It is intended to be a convenient 
  alternative to scp, allowing the transfer of files without having to open 
  another session and re-authenticate. zssh is an interactive wrapper for ssh 
  used to switch the ssh connection between the remote shell and file transfers.  
  Files are transferred through zmodem protocol, using the rz and sz commands.

4. RCP - remote file copy

  This utility is handy for transferring files from one Linux system directly
  to another using remote shell.  It does not prompt for passwords, and it 
  performs remote execution through rsh requiring the same authentication.
