Hint: you need to learn how to create a text files. What information about the user is there in the file? How to read file, a.k.a file handling? How to create new user through the command line?

Store into a variable and use that variable say $user

I have seen other homework problems receive favorable responses - the difference is that the person asking the question has shown the work that they have already done, and is asking what they are doing wrong, rather than asking "how to do this". Can you amend your question with what you have already tried?

Create a file with name: text witch contains all users name.
for example my text file contents
usertemp
this is only one test user name.
Then create bash script file like this
run.sh
#!/bin/bash
while read line; do
useradd $line
done < text
Make the script run.sh runnable by type in terminal
chmod +x run.sh
At last run script with
./run.sh
Running above script may need root privileges.
sudo ./run.sh
Now these users cant log on because we have not assign any password to them.
[ToDO]
- Assign password for created list of users.
- Difference between using
adduseranduseradd, in this situation. see
- Read username, password from only one file, text.

Remove redundant
chmod 777 run.shas wjandrea said on comment, its only make the script readable writable and executable for everyone see moreUse read command in script instead of
more, to read line by line. I think its better in speed.

Why are you usingmoreinstead of just reading the file? i.e.while read line; do ... done < text. Also runningchmod 777thenchmod +xis redundant.
