You should go through the Unix tutorial and start learning vi. See
notes on Unix, etc for pointers to that material and see the
quick vi notes for a useful summary of vi
For this "lab", your assignment is simple:
Part 0: Accounts
Make sure that you have joined the class' Piazza site. Also make sure that you have
a topcoder account (topcoder.com).
Part 1: Create a private directory for cs140
Log onto a lab machine, and create a directory in your home directory called cs140.
Use lower-case for the "cs". Then protect that directory so that you have read and write access to
it, but no one else does. If that last sentence confuses you, remember to read
the tutorial on chmod which
is part of the lecture notes.
Part 2: Put a picture of yourself in your home directory
I'm sure you have a jpg of a picture of yourself somewhere. Copy it to
your home directory using scp or ftp, or even email and saving. Whatever,
store it in the file me.jpg in your home directory and make sure that it
is readable by the world. I've got mine in my home directory (/home/plank).
Part 3: Create a file called me.txt with some personal information
Use vi to create a text file called me.txt that has the following information:
Format it however you want. Create it from scratch, and do not copy it. Below is an
example of mine.
- Your name
- Your Topcoder username
- Your academic history
- Your major
- Why you are majoring in whatever your major is.
Put this file in the directory cs140 -- this is so that other people cannot
To submit this lab
You will submit this lab on Blackboard. Follow the labs link and submit
using the Lab 0 link.
For this lab, we'll have you submit your cs140 directory. To do so:
The TAs will then verify
that your directory and me.jpg have the proper permissions and that
you are on both Piazza and TopCoder.
to it (cd ~/cs140/), verify that your me.txt is in the folder as
instructed in part 3.
- Create a tar file for the directory by
typing the commands:
tar cvf lab0.tar cs140
The "cd ../" command takes you back out of the directory to the parent directory.
- Submit the lab0.tar file to Blackboard.
