It's a bit unclear what you're really trying to do here, but I'm guessing
you want to pre-populate the user's input for a read command, to provide
a "default" that can be edited.
If you use read with the -e option (to enable readline), you can also use
the -i option.
-e use Readline to obtain the line
-i text use TEXT as the initial text for Readline
unicorn:~$ read -p 'What is your name? ' -e -i "$LOGNAME" -r name
What is your name? greg_
Where _ represents the cursor. The string "greg" is pre-populated
from the -i option, and can be backspaced or whatever.
