Due - Tue - 18 Sep.

1) Log into your CERI Account.


CERI UUID:_________________________


CERI PASSWORD:_____________________

2) [2*] Create a directory in your account for this course - you might call it something like ESCI7205.

3) [2*] Create 4 subdirectries: homeworks, notes, scripts, and programs (call this one "src")

4) [2*] Copy the files f1.dat and f2.dat from /gaia/home/rsmalley/ESCI7205 to the homework directory you created for this course.

5) [2*] Use the cat command to make a file that has the following 5 lines
11
12
13
14
15

6) [2*] Use the paste command to combine f1, f2 and the file you made in question 5 into a file with 3 columns and 5 lines.

7) [*] Look at the "big" file you made in question 6 using the cat and more commmands. If it is not correct - try again.

8) [2*] Make a link to the "big" file you made in question 6 in the directory for the course (not the homework directory). Look at the file from the course directory, if it is not correct, fix it.

9) [2*] Use cat to combine f1, f2 and the file you made in question 5 into another big file.

10) [5] Look at this file you made in question 9 with cat and more. Describe the difference between what happened in question 6 and question 9.


Notes on HW -- the questions with * means this is something you do only on the computer. I will look at the files to see what you have done. You do not need to be printing anything out.

The questions without a * mean that you have to write/do something on paper to be handed in.

This HW is a slight extension of HW1. Use it to construct the directory structure correctly (4 subdirectories) and get the link correct.
