Homework
1 - Basics
Given out August 28, 2019
Due at 4:00pm on Wednesday, September 4 via the BLACKBOARD system
You will need access to a Unix (or Unix-like) system for this assignment. There is no requirement to use a particular system, or kind of system.
You will need to submit a writeup with your name, student ID, and the answers to the following questions. Please create a reasonably formatted pdf file and submit it to the “Homework #1” dropbox via Blackboard. A simple way do to is to use a word processor: you can copy and paste from a shell window if needed.
Scoring is 1 point per question.
- Briefly describe the system you are using. (e.g. "Redhat 7.2 running on my PC." or "wsunix.wsu.edu" or “ssh1.eecs.wsu.e” or some similar brief description.)
- What is the output of uname -a?
- What directory are you currently in?
- How do you know what directory you are in?
- What is the output of who am i?
- What is the output of whoami?
- How do the two differ?
The next few questions use the man page for ls. - How is the ls command described in the "Name" section of the man page?
- How many options are there to the ls command?
- How would you invoke ls to get output like the following (ignore the dates, username, and group; focus on what files are being listed)? Note that some of this will not make sense until we have completed covering the file system.
