SCF resources are commonly accessed by logging into one of the SCF machines, which will put you into a UNIX command line interface. More specifically, by default, you’ll be interacting with the machine through the bash shell. (But note that we also provide browser-based interactivity through our JupyterHub service.)
For more information, the SCF has developed:
an introductory tutorial about the UNIX command line and
a more advanced tutorial about the bash shell.
We also recommend Software Carpentry’s UNIX shell workshop for novices (with an accompanying video.)).
