if you are using

 Set-PSReadLineKeyHandler -Chord 'Ctrl+d' -ScriptBlock { [System.Environment]::Exit(0) } 

you can make it

 Set-PSReadLineKeyHandler -Chord 'Ctrl+d' -ScriptBlock { ' ' ;  [System.Environment]::Exit(0) }

to output an empty line firest (there is no need for a space between the quotes, you can put any text 'exiting' or a an empty string, or even $null there.)

Because PSReadline is responsible for handling (and changing or acting on) commands as typed but before they are submitted it won't insert a new line, and if you type EXIT [enter] you already have a new line. Exit is immediate exit and if it suffixed lines to output that would change the results of existing code which uses exit, so it would be a breaking change.

As explained elsewhere #16256 ctrl-D isn't a shortcut key but the end of file marker; different OSes use different characters (ctrl Z gets you out of windows' nslookup, but ctrl D gets you out of the unix/linux version) and not all shells see input as a continuous file stream.

Hi,

I never argued about ctrl-D. Ctrl-D isn't any shortcut, it's just a way to let the shell send an EOF to the process stdin.
The problem here is that no new line is print after an EOF.

The same issue exists when the shell reads an EOF, it's not related to ctrl-d at all.

Above you can see that every shell writes a new line when reaching the end of the stdin, but powershell doesn't and clobbers the prompt.
No ctrl-d involved at all this time, just regular end of stream reached.

I'm not sure if the issue is actually printing the prompt when there is no more input.
You're right at best the behaviour is untidy. I thought this and the referenced query were basically the same thing, my bad on that.

Well, other shells don't print the prompt if there is an EOF.
I think that this could be solved either by printing a new line, or by suppressing the last prompt.
I looked at the code, the latter is a bit more difficult.

I just retried with a fresh build, and now ^D doesn't even terminates the shell.
