# Intro to the Linux Command Line



## This presentation



[https://github.com/gabeclass/introlinux](https://github.com/gabeclass/introlinux)



## About

These are reference materials for the PiCSciE workshop **Intro to the

Linux Command Line** at Princeton. Most of material is covered

interactively and adapted as much as possible to the audience at any

given workshop. At the start of the workshop, participants will see

how to capture every command they type, along with the output and any

notes and comments -- **everyone will have a personalized record of

what happens in the session.** Consequently, very little is posted on

this page.



This workshop does not assume prior experience with Linux/Unix systems

or the bash shell, nor does it assume that you have previously worked

with a command-line interface (CLI) to a computer.



## Adroit

The workshop *does* assume that you have an account on the Adroit

cluster (this is a shared Linux cluster at Princeton on which we will

do our work). You do not yet need to know how to access Adroit via

SSH. Instead, most of the workshop will rely on a web interface called

**myAdroit** that provides a command-line shell plus a graphical file

browser.



To connect to myadroit, you must be on the Princeton **eduroam**

network (the **puvisitor** network will *not* allow a connection to

Adroit), and you must be able to Duo authenticate. If you were off

campus, you would be establish a connection to Princeton's VPN first.

OIT has

[instructions](https://princeton.service-now.com/snap?id=kb_article&sys_id=ce2a27064f9ca20018ddd48e5210c745)

for how to do that.



When you're ready, please log in to myadroit

[here](https://myadroit.princeton.edu/).



## **WARNINGS!**



* **Linux is _case-sensitive_** (macOS may or may not be, depending on

  how your hard drive's filesystem was configured).



* **The command-line is _unforgiving_!** Type things *EXACTLY* as you

  see them, and avoid interpreting (and don't assume the computer will

  interpret anything for you -- be precise).

## Google Survey

Near the end of the workshop, you'll be asked to fill out a brief (3-5

mins) survey. When the time comes, please

* Afternoon session (Intro to HPC on the Princeton Clusters)



* Wednesday session (Command Line Power Tools -- moves faster, a bit

  more advanced, but worth seeing even if you can't keep up this time

  around)
