In this portion of the course, you will learn how to become a user of the UNIX operating system, and how to use the Bourne shell to write UNIX applications of your own.
UNIX COMMANDS
UNIX offers a wide variety of services and is constantly changing as new and better services are introduced. In CS 101, we will focus on the following UNIX commands and concepts (underlined items have been discussed in lecture):
login
passwd
who
finger
hierarchical file system
cd (absolute & relative addressing; .. and .)
pwd
ls (-l and –t)
mkdir
rmdir
mv
cp (-r)
rm (-r)
chmod
echo
cat
more
| < > & ;
filename generation
grep
sort
telnet
ftp
man
UNIX PROGRAMMING
You will learn the basics of the UNIX (Bourne) shell language:
variables
command line arguments
assignment
conditionals
iteration
input/output
invocation of shell programs
Sobell, M. (1995). A Practical Guide to the UNIX System, Third Edition. Redwood City, CA: Benjamin/Cummings.
Read all of Chapters 1 and 2. In Chapter 3, read about: finger, who, man, echo, date, cp, mv, grep, sort In Chapter 4, read pages 65-79. Read all of Chapters 5.You may also find it useful to read Chapter 8 on the UNIX editor: vi.
Each of the following six tutorials cover the introductory UNIX concepts you'll need, in differing styles and at different levels of depth. Find one that you're comfortable with, and work through the material, keeping in mind the required commands and concepts listed above.
Now that you are a UNIX user, it is time for you to become a UNIX programmer. Each of the following five tutorials contains the material you'll need to write your Bourne shell scripts in labs 15, 16, and 17. Again, choose one that you like and work through it. Each is roughly equivalent to the material in Chapter 10 of the textbook.
