CS 4010 Lab 4

CS 4010 Spring 2018

Lab 4

Find a computer and log into the OSX side using your CS login name and password.

Open Firefox and find the class web page.

Open TextWrangler - use the finder window and go to applications.
Open a new text file, called <insert your name>Lab4.txt, to record your work today - you will paste in some of your command lines. The header of the file should look like:

Your Name

Lab 4
February 23, 2018

Find the Terminal - use the finder window and go to applications and then utilities.

Make sure you have the examples from our book:

In your home directory, you should have created a directory for CS4950.
Go to the companion web page for our book: http://practicalcomputing.org/
Click on "Downloads" and then on "[Examples]"
Save the downloaded file pcfb_examples.zip in to your CS4950 directory. (You may need to move it from your downloads directory.)
Double click on the file and it will unzip and give you a directory - inside of that directory are the example files that go with the book.

The first part is to practice with some basic unix commands. This is a continuation of Lab 3 and we will be working in pcfb/sandbox/test021408/

Find out how many lines in shaver_etal.csv have Goose lake and July (this may take several steps and involve grep)

Go through the example on page 76 of searching across multiple files with grep.

Work though the curl examples on page 79 of the book. You will need to use the urls from the errata:

How to change your shell to bash and create .bash_profile

Here is a way that users can change their terminal to bash:

chsh -s /bin/bash

Then you have to enter your user password and open a new terminal window to see the changes.

How-to create a bash_profile:

Start up Terminal
Type "cd ~/" to go to your home folder
Type "touch .bash_profile" to create your new file.
Edit .bash_profile with nano, pico, or TextWrangler.
Type "source ~/.bash_profile" to reload .bash_profile and update any functions you add.
