Feature Request: Ability to clone current tab

Description of the new feature/enhancement

Ability to clone the current tab preserving the current directory

Proposed technical implementation details (optional)

This is a dupe of a bunch of related conversations:

#1756 (comment)

Just chiming in;

_ (profile,working dir, environment var, etc)._

Anything about the actual process on the other end is, in the general case, impossible to replicate. The connected process could be ssh.exe, whose environment variables and working directory have no bearing on the detectable environment and working directory from the terminal side. The same actually, weirdly enough, applies to WSL. It doesn't use "working directory" and it doesn't expose its environment variables to interested Windows processes in any way.

Powershell doesn't even set the current working directory, so its directory can't be detected (!) either.

#2315 (comment)

This is one of those things that is impossible in the general case but technically possible. There's a lot of intricacies here, like:

cmd
powershell
cd d:\users

well, powershell isn't the first process we launched. we'd ignore the path d:\users

(in powershell)
cd d:\users

we'd ignore d:\users because powershell doesn't actually set the current working directory (!!)

If your "shell" is ssh [email protected] (where we strictly define shell to be "the first process Terminal spawns on your behalf"), its working directory is always going to be C:\windows\system32 regardless of what the remote working directory is.

I'd rather not provide the feature than provide the feature with so many caveats that they'd fill a documentation page. ☹️ sorry.

#1536 (comment)

No, because that would likely be neigh impossible to do in a general sense. How would we duplicate an instance of vim for example? What if the foreground process has opened some sort of file for exclusive access - how could we duplicate that process?

If there's a way this can be done safely and generally I'm all ears for proposed technical solutions, but I don't think it's something that's possible, so I'm not going to be investigating it.

If this is generally technically possible, I'd love to implement it. But I'm/we're not sure that it'll work right in most scenarios, so I'd rather not add a feature that in the general case doesn't work the way you'd expect.

This issue has been marked as duplicate and has not had any activity for 1 day. It will be closed for housekeeping purposes.

@zadjii-msft I'm not asking to clone a process the tab lauched.
It is a common use case to launch a terminal navigate to a directory and launch a few more.
That's what this feature request is asking, nothing else.

Can you reconsider opening this feature request again?

[zadjii-msft]

I didn't close this based on the fact that it's impossible to clone a process's state generally - I closed it because it was a dupe of like 3 other feature requests. Also, we'd consider the path duplication if it was generally possible. Our current understanding is that we don't think that's possible - see my above comment, esp. the #1756 and #2315 comments on why we don't think that's possible.

Got it, thanks @zadjii-msft
