I used the script program to record an interactive session:

$ script
$ echo<-<-<-<-printf "hello\n"
$ exit

The sequence <- is representing the backspace character.

I want the following as output:

$ printf "hello\n"
$ exit

But the actual result contains all individual keystrokes (looking with cat --show-nonprinting).

I tried reading line-by-line with the read command. It does edit out the backspaces, but it also removes the command prompt, and it seems it converts \n into n.

I'm looking for a way to have the text the user was seeing on screen (command prompt, edited input and command output -- colors don't matter).

For reference a sample output:

^[[?2004l^M^[[?2004h$ echo^H^[[K^H^[[K^H^[[K^H^[[Kprintf "hello\n"^M
^[[?2004l^Mhello^M
^[[?2004h$ exit^M
^[[?2004l^Mexit^M
