Revision as of 13:01, 21 May 2019
We are developing bootcamps on the most important topics and skills that are used throughout our courses. These can be used by incoming undergraduate students to get a head start, incoming graduate students to review, or current students to refresh/remediate.
Contents
Programming Bootcamps
Python
Getting started with Python and this bootcamp.
- Follow along this tutorial -
- Work on solving these problems - https://www.hackerrank.com/domains/python
- Get Python installed on your computer -
- If you are a current or incoming ISU student, or an ISU alumni, sign up for the ISU CS Mattermost, go there to get help.

Reading
To begin with, read through - Linux Tutorial
System Setup
Next, you need to have a Linux system that you can use.
ISU CS Account
If you are a student in a CS course at ISU you will be given an account on the CS linux systems (see CS Accounts and CS Lab Computers).
Linux on Your Computer
You can also download and install VirtualBox on your computer, download a Linux install image (e.g., Ubuntu Linux), and then install Linux into your virtual box.
Mac OS X
You can also use a Mac OS X computer - most (but not all) commands are the same on Linux and Mac OS X. On Mac OS X, to get to the terminal you click on Finder, then Applications, then Utilities, then Terminal.
Try it Out
Once you have your Linux system to try out, open up the terminal (also called the shell, or command prompt), and try out the following commands. Note that all commands in Linux are case-sensitive.
- uptime - how long since last system reboot
- df - information about disk free space
- whomi - which user is currently logged in on the terminal
- hostname - what computer are you currently running commands on
- pwd - which directory are you inside of
- clear - clear the terminal screen
Other commands that you will be using include the following.
- cd - change directory
- mkdir - make a new directory
- ls - list directory contents
- cp - copy files
- rm - remove files (be careful, there is no recycle bin or trash - once you delete, it's gone)
- rmdir - remove directory
Here is an example session from running on the CS server using all of these commands.
