Secure File Transfer on Linux
SCP is used to securely copy and retrieve files from a host.
To upload a file from the local system
scp SourceFile username@hostname:folder/TargetFile

To upload a directory from the local system
scp -r SourceDir username@hostname:TargetDir

To retrieve a file from the remote system
scp username@hostname:folder/SourceFile TargetFile

SFTP is used to securely connect to a host and interactively transfer files. It can also be used in the same manner and format as scp. NOTE: SFTP cannot copy directories.
To connect to a host using sftp
sftp hostname

Once connected, a call to help will show you the commands available
help

But the basic command to retrieve a file will be
get path/SourceFilename

And the basic command to upload a file will be
put path/SourceFilename
