Question

sing the attached file as a "database" of users, develop an application that reads the users.txt file, and adds each one as a new user. Each user must also have a password, though in the interest of brevity, they may all be assigned the same one. Provide me the source code and a copy of your system's /etc/passwd file. Note: it is perfectly acceptable to "leverage" code from another source provided: 1) you understand what the example code is doing, and 2) you write it yourself. Remember to give attribution to any code you use that you didn't write. 1. Pittman,Mckenzie,Sales 2. Donovan,Moriah,Accounting 3. Barnes,Gabriel,Sales 4. Monroe,Maximillian,Management 5.

Answer 1

Please find the following shell script to read the file and create the user with default password as "admin123".

Program:

#!/bin/bash

if [ $# -ne 1 ]
then
echo "Usage: $0 <accounts.txt>"
exit
fi

fileName=$1

#change the default password as needed
defaultPasswd="admin123"

#following awk script cuts the first name and first character from last name to form the username of the account
#example "1. Pittman,Mckenzie,Sales" user name is "pittmanm"

awk -F"," '
{
print $1" "$2
} ' $fileName | awk ' { print tolower($2substr($3,1,1)) }' | while read userName
do
#useradd command is used to add the user name with default password and with home directory
useradd -r $userName -m -p $defaultPasswd
if [ $? -eq 0 ]
then
echo "User: '$userName' is added with default password: $defaultPasswd"
else
echo "User: '$userName' is not added due to error: $?"
fi
done

Output:

User: 'pittmanm' is added with default password: admin123
User: 'donovanm' is added with default password: admin123
User: 'barnesg' is added with default password: admin123
User: 'monroem' is added with default password: admin123
User: 'maynards' is added with default password: admin123
User: 'mayere' is added with default password: admin123
User: 'reevess' is added with default password: admin123
User: 'oneills' is added with default password: admin123
User: 'jacksonh' is added with default password: admin123
User: 'leea' is added with default password: admin123
User: 'goldeni' is added with default password: admin123
User: 'tyreset' is added with default password: admin123

sample file "/etc/passwd" :

pittmanm:x:991:991::/home/pittmanm:
donovanm:x:993:991::/home/donovanm:
barnesg:x:994:991::/home/barnesg:
maynards:x:994:991::/home/maynards:
tyreset:x:993:991::/home/tyreset:
