Challenge Lab for Week $7$ cislinux.hfcc$.$edu

This lab will Challenge you and your recall of the cislinux.hfcc$.$edu lab work for the week.

Challenge Lab: Each Challenge Lab is worth $20$ points.

$1)$ Create a script called week$7.$sh with a text editor.

$2)$ Fully comment the script where needed.

$3)$ Your output file will be called week$7$printf.out.

$4)$ You MUST have a function in the week$7.$sh script to display your student header

information in the week$7$printf.out file using $>$ and $>>$ to redirect the output and

information shown below. Example:

$*******************************************$

$*$ Brent Fulton

$*$ Username: bfulton show using one of the methods learned

$*$ Date: current date and time using $`$date$`$

$*$ Assignment: Week $6$ Challenge Lab

$*******************************************$

$5)$ Make sure the output is neat and use extra echo commands to insert lines into the

output for easier reading.

$6)$ Use blank lines in the script for easier reading in the script as well.

$7)$ The script should perform, complete, and show the following information:

a$.$ Function in script should show the student header information as discussed above

in the week$7$printf.out file.

b$.$ Use the echo commands below to create a visual separator in the

week$7$printf.out file.

echo $>>$ week$7$printf.out

echo $>>$ week$7$printf.out

c$.$ Your script must clear the screen and ask for a SYSTEM username to

process. $($This will NOT appear in the week$7$printf.out file, only on the

screen$)$ Read in the response $($must be operator$)$ and use that variable

with the grep command for the following item.

NOTE: Do NOT test this script with root! Since the pattern of root can

be found in multiple locations in the $/$etc$/$passwd file, it would produce

strange results.

NOTE: Your script should work with any other username such as mail,

games, apache or ftp as well if you would like to test the script with a

different account. It will of course change the output below; however,

it would be a good test to verify your script is working correctly.

NOTE: Your script MUST use the printf command for the following item!

d$.$ Using the variable from the previous item and grep, cut and printf commands

with the $/$etc$/$passwd file, have your script add the following to the

week$7$printf.out file:

i$.$ Name: operator

Password: x

Userid: $11$

Groupid: $0$

Description: operator

Home Directory: $/$root

Default Shell: $/$sbin$/$nologin
