 ===== What Is SFTP? =====
-In Linux, you can use the Secure File Transfer Protocol (SSH File Transfer Protocol) (SCP) from the command line (CLI) (the sftp command) to securely copy files and directories between remote hosts.

-In most cases, SFTP is preferable to FTP because of its underlying security features and ability to piggy-back on an SSH connection. FTP is an insecure protocol that should only be used in limited cases or on trusted networks. FTP is NOT available on CS Department computers.

+  * pwd: show remote working directory.
+  * ls:  view contents of the current remote directory.
+  * cd:  change remote directory.
+You can direct commands towards the local file system by preceding them with an “l” for local.
+  * lpwd: show local working directory.
+  * lls:  view contents of the current local directory.
+  * lcd:  change local directory.
+==== Transferring Remote Files to the Local System ====
+Transferring files from the remote system is accomplished by using the appropriately named “get” command:
+To download a file from the remote host.
+  get remote_filename
+To download a file from the remote host and rename.
+  get remote_filename new_local_filename
+To download a directory and it's contents.
+  get -r remote_directory
+To preserve full file permissions and access times during the copy, use the -p flag.
+  get -p remote_filename
+==== Transferring Local Files to the Remote System ====
+Transferring files to the remote system is accomplished by using the appropriately named “put” command:
+To upload a file to the remote host.
+  put local_filename
+To upload an entire local directory to the remote host.
+  put -r local_directory
+==== Quitting SFTP ====
+To quit a SFTP session use the exit command
+  exit
