sftp is used to securely transfer files between a local machine and a remote machine that is accessed via SSH. SFTP stands for Secure File Transfer Protocol.
$ sftp user@hostname Password: ********* Connected to hostname. sftp> put filename.txt sftp> mput file1.txt file2.txt file3.txt sftp> get file.txt sftp> mget file1.txt file2.txt file3.txt
Useful Options / Examples
$ sftp <username>@login.engin.umich.edu Password: ********** Connected to login.engin.umich.edu. sftp>
This is how you begin the sftp process. It is done the same way as when you SSH into a machine, except you use the sftp command instead of the ssh command. You must have access to the machine and provide a password. You can try this by remote accessing CAEN with your firstname.lastname@example.org and providing your kerberos password as the password.
