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.

Beginners

The Linux Command Line – A Complete Introduction

• By William E. Shotts Jr.; No Starch Press, January 2012; about $30 – $40 in print or as ebook.

Fairly gentle tutorial introducing Linux in general and command line usage in particular (2012, new and promising). --stern

Introduction to the Linux Command Shell For Beginners (pdf)

Provides a "fast and simple introduction to using the Linux command shell and some of its basic utilities. Assumes very little or even no prior exposure to the Linux command prompt. References to DOS commands are made where appropriate. This document was meant to accompany an instructor-led tutorial on this subject, and therefore some details have been left out."

Very short, but does cover the basics of managing files and directories, and touches on key concepts like redirections and pipes. --stern

Intermediate

man bash

help cmd

The Bash manual page is the definitive resource on capabilities and syntax. Covers all details of bash precisely and concisely. The help command gives the paragraph from the man page (or a close version thereof) relevant to the bash builtin cmd.

Version note: A couple of major versions of Bash are in concurrent popular use, mostly Bash-3, phasing in Bash-4. While simple scripting concepts are applicable to all versions, each version introduces capabilities for more versatile scripting, such as array variables, arithmetic loops, and regular expression matching. The man command always shows the capabilities of the version in use on your system. See http://bashcookbook.com/bashinfo/#bash for other versions. --stern

Bash Reference Manual

"A brief introduction to features found in Bash." For a definitive reference on shell behavior please review the Bash manual page.

Advanced Bash-Scripting Guide

"This document is both a tutorial and a reference on shell scripting with Bash. It assumes no previous knowledge of scripting or programming, but progresses rapidly toward an intermediate/advanced level of instruction. The exercises and heavily-commented examples invite active reader participation."
