Probably a dup; I couldn't find it.

WindowsTerminal 1.22.2411.18002 (preview)

If, in WT, I copy (Left-Drag, Right), as pictured,

and paste into notepad, I get what's expected (no extra stuff).

Image

If I do the same in WSL

Image

and paste into notepad, I get (this is hard to picture)

On the line immediately after the second "foo" there are 128 (terminal width) spaces followed by the next prompt; there is not a blank line.

There has been no comment so I tried it again. The result was the same. Copying several lines (which include a blank line) in WSL and then pasting into notepad results in 128 spaces (my terminal width) where the blank line was, and no newline. I tried this using both bash and tcsh in WSL with the same undesirable result. It does not happen when I do the same experiment in a Windows shell.

Most of the team was out on vacation over the holidays. What shell are you using? If it's bash, can you try launching a nested shell with env -i bash --norc --noprofile and then try executing echo and copying the results?

That works OK. In fact, I can't get it to screw up in bash now. But in tcsh, it's as described. In both shells, I used printf "foo\n\n" to test.

Thanks for filing! Can you repro this under a debug tap and share your results? Here's a guide for debug tap: https://github.com/microsoft/terminal/wiki/Troubleshooting-Tips#capturing-a-debug-etl-trace

Also, can you confirm whether you're using Tenex C Shell or TCC / TakeCommand /?

/home/vefatica> tcsh --version
tcsh 6.20.00 (Astron) 2016-11-24 (x86_64-unknown-linux) options wide,nls,dl,al,kan,sm,rh,nd,color,filec

The printf command was recalled from the history. In tcsh I see this.

In the debug tap I see this.

When I copy (left-drag) the 5 lines of output from tcsh and paste into notepad, I get this.

Hey, thanks for that!

CSI Ps G  Cursor Character Absolute  [column] (default = [row,1]) (CHA).

I see that tcsh is emitting CSI G to move the cursor to column 92.
It is then emitting two spaces, plus a carriage return.

It is almost explicitly jumping to the end of the line and emitting spaces so that it wraps. That is the effect of writing spaces off the right-hand side of the screen.

Looks like tcsh's doing.

Thanks, Dustin. That's bizarre. I wonder what the motivation was.
