Creating users from .txt file

I'm given the following ".txt" file, containing a list of usernames:

user1, user2, user3, user4, user5, user6, user6, user7, user8, user9, user10

From the following, I have to create different users, using each value as the username and same value for the password.

I've tried to, from that list, create a new one writing the usernames in columns, and then create the users from that new .txt file.

IFS=$'\n'

lst1=$(cat /path/of/file/a.txt)

for i in $lst1
do
   a1=$(echo $i |awk '{print $1}')
   useradd $a1 
  a2=$(echo $i | awk'{print $1}')   echo-e "$a2\n$a2" | passwd $a1   
done

But it's not working at all..., I can't take the comma out from the string, and it doesn't allow me to create the user.

Anyone could advice me on how to do it properly?

You may want to read [Read a file line by line assigning the value to a variable](http://stackoverflow.com/a/10929511/1983854) – fedorqui Apr 25 '17 at 09:16
That's a very poor design for the input. Use either comma delimited or whitespace delimited, or perhaps go for newline-delimited. – tripleee Apr 25 '17 at 09:25
Also, your quoting is hosed. See http://stackoverflow.com/questions/10067266/when-to-wrap-quotes-around-a-shell-variable – tripleee Apr 25 '17 at 09:25
