About perl -d -e "1;"

[abdan]

I'm noobie using perl -d -e "1;" I installed Term::readline and thought the same as using Bash on terminal the backspace is undo the last key input/pressed, but the perl debug behave undo entire current line i.e. delete the line How to have it the same as doing Bash on terminal, i.e. the backspace is undo the last character input ? Thanks much
