SECTION III. PRESENTATION

1. Learning Step / Activity 1. File Structure

Method of Instruction: Conference / DiscussionInstructor to Student Ratio: 1:16

Time of Instruction: 1 hrMedia: Large Group Instruction

a. Hierarchical file structure

(1) The UNIX file structure is very similar to the family tree. All files are connected. This type ofstructure allows you to organize files so you can easily find any particular one.

(2) One of the strengths of the UNIX file structure is its ability to adapt to different needs of the users.This can be done by taking advantage of the structure by strategically organizing your files sothey are most convenient for you.

b. File Names:

(1) Ordinary files and directory files created in the UNIX file structure will have a file name composedof 1 - 14 characters.

(2) There are exceptions. The directory name for root which is named for root which is named/ andis referred to by this single character. No other file can have this name.

EXAMPLE: MARCH, march, and March are three different file names.

(3) File name extension is part of the file name followed by an embedded period. Extensions areused to make files names easily understood.

EXAMPLE: Comp.c - C ProgramsComp.o - Object Programs

Comp.t - Test Programs

c. Start-up Files:

(1) There are some files that should be included in all login directories. They are called start-up files.They are:

a) .profile: Your directory would contain this file if your system uses the Bourne Shell(Standard UNIX system V).

b) .login: Your directory would contain this file if you are in the C shell.

(2) The start-up files should contain information such as the following:

a) Type of terminal youre using.b) STTY utility to establish line kill and erase keys.

NOTE: Conduct a check on learning and summarize the learning activity.1. How many characters can a file be composed of?Ans: 1 - 14 characters.

2. What files should be included in all login directories?

7

8/8/2019 25B10I02

8/28

Ans: .profile and .login

2. Learning Step / Activity 2. Logging On


Time of Instruction: 40 minsMedia: Large Group Instruction

a. Logging on the system: When you log on, the system does several things. First, it verifies by use of apassword that you are authorized to sign on the system. Then, the system will establish a SHELL foryou to work in. The system administrator determines what SHELL you receive. There are manyavailable, the most common are:

(1) Bourne Shell (pg. 202): This shell is commonly used for the average user. Its default prompt is$. We will use this shell during our classes.

(2) C Shell: Is used for programmers using the C language. Its default prompt is %.(3) Super User Shell: Sometimes referred to as root, is a very powerful user shell. User privilege for

this shell is normally limited to the system administrator.

b. Once your Shell is established, the shell will read your profile and execute the commands to set up asyour working environment. This file is similar to the AUTOEXEC.BAT file in MS-DOS. The loginprocess looks like this:

9600 Login: stul

Password: (not displayed)

NOTE: Conduct a check on learning and summarize the learning activity.1. What shell is commonly used for the average user?Ans: Bourne shell.

3. Learning Step / Activity 3. Directories


Time of Instruction: 40 minsMedia: Large Group Instruction

a. Directories:

NOTE: Explain to the students the concepts of WORKING and HOME directories and the importance ofrelative and ABSOLUTE path names. Inform the student you will be discussing creating, deleting, andusing HOME directories.

(1) The WORKING directory is where you are working whenever you are logged on to the system.You will always be associated with one directory or another. The directory you are working out ofwill always be your working directory. No matter whose directory you are working out of, it willalways be your working directory.

8/8/2019 25B10I02

9/28

a) Accessing files: When accessing a file in a WORKING directory, you do not need a pathname; you only need a file name.

b) Whne accessing a file in any directory, you need only type in the command you wish to use tomanipulate file; then the file name.

EXAMPLE: cat fileb

NOTE: Give as many examples as you feel necessary to reinforce concepts of accessing files throughoutthe file system using relative and absolute path names.

(2) Home Directories: When logged on to the UNIX operating system, you are automatically placed inyour HOME directory/WORKING directory files.

NOTE: Conduct a check on learning and summarize the learning activity.1. What directory are you automatically placed in when you log in?Ans: Home directory.

4. Learning Step / Activity 4. UNIX Commands Overview


Time of Instruction: 1 hr 30 minsMedia: Large Group Instruction

a. Formation UNIX commands: The UNIX command format is:

$ command [options] [argument1] [argument2]

(1) Commands: Generally shortened forms of the function. They must be entered in lower case.(2) Options: Most options begin with a dash. Multiple options may be strung together. The order ofthe options is generally not important.

(3) Arguments: The names of files, directories, users, or other pieces of information needed by thecommand to execute.

b. Delete, interrupt, and cancel keys: The key sequences to perform these functions may vary fromkeyboard to keyboard. On an operational computer (PC), deleting a character could be orbackspace (BS); to interrupt a process or cancel a command line use . Otherterminals may use break or Del for process interrupts and @ for canceling command lines.

c. Password (passwd) utility (pg. 130): Changes log in password. New password must differ by at leastthree characters. The system will prompt for old password to verify who you are.

d. ls (pg114): The ls command displays information about the contents of a directory includingdescriptive information about the contents if desired. Wild cards similar to wild cards in MS-DOS canbe used with this command.

(1) * for any number of characters(2) ? for any character(3) [] a range or list of characters

e. cd (pg25): The cd command is used to change your location in the directory structure. The new

9

8/8/2019 25B10I02

10/28

directory becomes your current directory.

f. cat, more, and page (pgs. 23, 122, 130): Each of these commands print the contents of files on theterminal.

(1) cat: The cat command will display one or more joined files, beginning with the file specified in thefirst argument.

(2) more: The more command prints the file one screen at a time.(3) page: The page command prints the file one screen at a time in a backward or forward direction.

g. who (pg. 192): The who command will display the names of all users presently logged on thesystem. The display will include each users terminal number and log in time.

h. mkdir (pg. 121): The mkdircommand is used to create a directory or a series of directories.

i. rmdir (pg. 146): The rmdircommand is used to remove an empty directory or directories.

j. cp (pg. 34): The cp command copies a file from one location to another or from one file name toanother name.

k. mv (pg. 123): The mv command moves a file from one directory location to another. Note: existingfiles will be over written.

l. rm (pg. 146): The rm command removes a file from the specified directory.

m. date (pg. 43-45): The date command is used to check or change the date and time on the system.

NOTE: Conduct a check on learning and summarize the learning activity.1. What command will display the names of all users presently logged on the sytem?Ans: The who command.

2. What three commands print the contents of files on the terminal?

Ans: cat, more, and page.
