The purpose of this project is to become more comfortable with the UNIX command line interface. Use the general.asu.edu RedHat Linux system.

PART $1$: Read and review the following in your textbook:

Chapter $1$: pages #$3$ to $24$

Chapter $2$: pages #$25$ to $55$

Complete the Self Test and Exercises at the end of each chapter.

PART $2$: Experiment with some basic Unix commands:

Log on as your regular user to the general.asu.edu

Notice the CLI default prompt components: $[$user @hostname $|$ dir$]$

use the pwd command to identify your location

use the cd $/$ command to get to the root of your directory tree structure

use the cd ~ command to get back to your home directory

HAND$-$IN: Screen Capture #$1$ of of the above activities

PART $3$: Learn about commands to get help:

use the man ls command to review the ls command

use the info ls command to review the ls command

use the help command

HAND$-$IN: Screen Capture #$2$ of of the above activities

PART $4$: Learn about commands to navigate the directory tree structure:

use the ls $$ali $/$ command to review the contents of the $/$ directory

Review the Linux Filesystem Standard $($FSSTD$)$ and document the following directories$$ contents

$/-------$

$|--$bin

$|--$boot

$|--$dev

$|--$etc

$|--$home

$|--$lib

$|--$mnt

$|--$opt

$|--$root

$|--$sbin

$|--$tmp

$|--$usr

$|--$var

$3.$ use the cd etc OR cd $/$etc to change your default directory to the etc directory

$4.$ use the ls $$ali command to review the contents of the $/$etc directory

$5.$ now, change your directory to $/$dev and use the ls $$ali command to review the contents of the $/$dev directory

$6.$ get back to your home directory and use the mkdir test$1$ command to make a directory in your home directory

$7.$ use the cd command to change into the test$1$ directory

$8.$ create a file in the test$1$ directory by touch file$1$

$9.$ use the ls command to view the details of the file$1,$ What options do you use to see the detail?

$10.$ rm file$1$

$11.$ exit the test$1$ directory

$12.$ rmdir test$1$

$13.$ use the cd$,$ mkdir, and cp commands to make a directory named test in your home directory and copy the $/$etc$/$passwd file to $/$home$/$test$/$passwd$.$bak file

type: cp $/$etc$/$passwd passwd.bak

$14.$ HAND$-$IN: Screen Capture #$3$ of of the above activities

PART $5$: Learn about commands used to view contents of files:

use the cat command to review the contents of the $/$home$/$test$/$passwd$.$bak

type: cat passwd.bak

$2.$ now add the $|$more to the last command $($see what happens when you push the up arrow curser key$-$it recalls the last command$)$

$3.$ now try to cat the passwd.bak file but look at the first few lines and then the last few lines using the head and tail commands

type: head passwd.bak and tail passwd.bak

$4.$ let$$s now add the n$2$ option to the head and tail commands and see what happens

$5.$ let$$s look more at the cat command and redirection of output to a file:

type: cat $>$ file$1$ and enter a paragraph about how you feel about Unix. Hit the ctrl and d to exit

$6.$ create another file: ls $-$ali $>$ file$50$

$7.$ add to that file: cat $/$passwd$.$bak $>>$ file$50$

$8.$ review your work using the cat command

$9.$ try to pull out any lines from the file$50$ with root: grep root file$50$

$10.$ HAND$-$IN: Screen Capture #$4$ of of the above activities

PART $6$: Let$$s practice utilizing files and directories in our file systems structure:

create the following hierarchical directory structures:

test

$|$

dir$1$ dir$2$ dir$3$ dir$4$

$|$
