while read user ; do
	useradd -m $user
	do_whatever_else $user
done

This presumes that this is a script you execute as `script < txtfile`
If you were doing it as a one-liner, then the last line would be
`done < txtfile`

Note that the < textfile would have to be after the done construct on
the while loop.  if you did:  `while read user < txtfile`, the read
command would open txtfile, and read the first line .... over and over
and over again  (is this what you're seeing?)


`useradd -m $user` should create the user and their home directory --
normally, in /home/$user , but you can change that with
`useradd -m  -d /some/path/$user $user `
