Lab 3

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 Lab3.txt, to record your work today - you will paste in some of your command lines. The header of the file should look like:

Lab 3
February 17, 2017

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

Make sure you have the examples from our book:

The first part is to practice with some basic unix commands. Each command line should be pasted into your TextWrangler file:

How many lines are in shaver_etal.csv?  (write your answer in Lab3.txt)
Open shaver_etal.csv    using less
Find the last line with text in it and paste it into Lab3.txt (not just commas)

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.

Try: curl "http://files.rcsb.org/view/1ema.pdb"
Comment on what you see. You may want to go to the url in a browser.

Try: curl "https://www.wunderground.com/history/airport/KMOD/2000/8/2/DailyHistory.html?req_city=Turlock&req_state=CA&req_statename=California&reqdb.zip=95380&format=1"
Now try: curl "https://www.wunderground.com/history/airport/KMOD/2000/8/[1-10]/DailyHistory.html?req_city=Turlock&req_state=CA&req_statename=California&reqdb.zip=95380&format=1" >> turlockweather.txt

Lastly using the example on page 80 create separate files for the Turlock Weather

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.
