SCP

Secure Copy, or SCP, uses Secure Shell (SSH) for data transfer and utilizes the same mechanisms for authentication, thereby ensuring the authenticity and confidentiality of the data in transit.

Mac/Linux

You will need to use an SSH v2 compliant terminal to move files to/from HPC. For more information on using SCP, use man scp.

Copying to HPC

In a local terminal, you can move a file or directory to a designated subdirectory in your account on HPC using the following syntax:

scp -rp /path/to/file/or/directory netid@filexfer.hpc.arizona.edu:/path/to/remote/destination

Copying from HPC

In a local terminal, you can copy a remote file from HPC to your current directory using the syntax:

scp -rp netid@filexfer.hpc.arizona.edu:/path/to/file/or/directory .

Shorthand

Note that the trailing period above refers to the current directory. See our Linux Cheat Sheet for more tips like this.

Wildcards can be used for multiple file transfers (e.g. all files with .dat extension). Note the backslash \ preceding *

scp netid@filexfer.hpc.arizona.edu:subdirectory/\*.dat .

Windows

Windows users can use software like WinSCP to make SCP transfers. To use WinSCP, first download/install the software from: https://winscp.net/eng/download.php
