HPC/Linux Guides
To use Carbon and other HPC systems, you will need to become familiar with the Unix/Linux ways of doing things. You will be navigating directories, create, view, and edit various text files, and run commands on the shell command line and in scripts. As you become comfortable and learn more about commands and shell features you will find that you get much more efficient.
There are numerous resources to get you started; some are shown below.
A note on free vs. paid content: Free web pages and PDFs provide mostly the extreme ends of coverage and style – either short introductions or detailed reference materials. Those are relatively straightforward to put together. True teaching materials intended to present a gradual learning curve, however, require quite some effort to prepare and hence usually are available for purchase only. Choose wisely.
