Look in info bash under readline in the function section. Also, look at the cut and sed commands for help in parsing the lines.

If you want an easier way to handle your problem, look at info gawk (especially the examples section).

Just a quickie example of reading input from a file.

Code:

$ cat file
Mr Jim Black
Mrs Jane Doe
last last last


$ cat doit
#!/bin/bash
while [ true ];do #endless loop
  read TITLE FIRST LAST
  if [ $TITLE = "last" ];then
    break # jump out of loop
  fi
  # Create user account here
  echo "Created Account for $TITLE $FIRST $LAST"
done <file

$ ./doit
Created Account for Mr Jim Black
Created Account for Mrs Jane Doe
