CSE 374 17au Homework 0
Due: Friday, Sept. 29, 2017, at 11 pm (you really really don't want to burn up late days on this one!).
The purpose of this assignment is to be sure that you have your
Linux environment set up for the quarter and that you can log in and
execute shell commands. For this assignment you must use
either your
account on the klaatu.cs.washington.edu
machine or your
own copy of the CSE Linux Virtual Machine. It is possible to use
another reasonably recent Linux system for many things, but we will
use the CSE systems to evaluate submitted work, and you need to
verify that everything you submit works correctly there. See
the Linux Resources page on the
course web site for more information about how to get started.
- (Shell) You must be sure that your
default shell is
bash
. Otherwise you will run into strange, baffling problems with shell scripts. Enter the commandecho $SHELL
. The response should be/bin/bash
. If the shell name is different (csh
,tcsh
, or something else), use the appropriate commands on your system to change your login shell tobash
. On many Linux and Unix systems this can be done with the commandchsh
orypchsh
.
- (Commands) Open a shell window and enter the following
commands. They should work without errors if typed exactly as shown.
(Exception: if you are using
klaatu
, omit thecd Desktop
command. There is noDesktop
directory onklaatu
accounts.) Thescript
command will capture the terminal session and save it in a file namedhw0.script
in the current directory.
cd cd Desktop # omit if using klaatu script hw0.script whoami echo $SHELL pwd uname -a cat /etc/redhat-release gcc --version -std=c11 exit
Notes: if thegcc
command generates a warning that -std=c11 is not a recognized option, your C compiler and, probably, your Linux version are too old, and you should use the current UW CSE Linux system for this class.
Thecat /etc/redhat-release
command should print a message that begins withCentOS Linux release 7.4
... . If it does not, or if you get a message that the file is not found, you are not using a properly configured UW CSE Linux machine, and you should repeat the assignment once you fix that.
- (Chatting) Go the course discussion board (link on the web site) and post a followup to the Welcome message to introduce yourself, and to get gopost to automatically track new postings for you.
Assessment: Your solution will be evaluated on how well it
follows the instructions and produces the desired results. Note:
the script
command captures everything,
including backspaces and other corrections as you are typing input.
It's fine if there is some of this in the submitted file, but if
there is too much clutter or too many mistakes, it would be best to
start over and get a reasonably clean hw0.script
file
to turn in.
hw0.script
file created in
problem 1. The drop box will allow you to turn in your homework up to
two days late, if you choose to use one or two of your late days, but
you are strongly advised to save your late days
for much later in the quarter when you may really want them.
If you are still trying to register for the course, email the
course staff (use the correct cse374-staff
email address)
to get a klaatu
account, and you will be able to run the
assignment there and submit using the dropbox.
If you create the hw0.script
file on klaatu
,
you can use scp
(winscp
on windows)
to transfer the file to your local
machine so it can be submitted using your local web browser.
If you are using the UW CSE Linux virtual machine, you can run a web
browser on the VM to submit the files from there.
