You can save the history to a file (say .username.history) with this command:

Code:
history -w $HOME/.username.hist

To read history back use:

Code:
history -r  $HOME/.username.hist



So our example username prompting script would do this:

Code:
HISTFILE=$HOME/.username.hist
# Clear history
history -c

# If previous history exists load it in now
[ -f "$HISTFILE" ] && history -r "$HISTFILE"

while true
do
    read -e -p "Enter your name (QUIT when done):" name
    #Put name into history
    history -s "$name"
    [ "$name" = "QUIT" ] && break
    echo "Hello, $name"
done

# Save history for next time we run script
history -w "$HISTFILE"
