Unexpected backslashes when remoting from Win to Nix #3923
Description
A minor cosmetic issue described in VSCode's Repo.
Steps to reproduce & actual behavior
If I start PwSH on my Windows-box:
PS C:\Windows\System32> $PSVersionTable
Name Value
---- -----
PSVersion 7.0.0
PSEdition Core
GitCommitId 7.0.0
OS Microsoft Windows 10.0.18363
Platform Win32NT
PSCompatibleVersions {1.0, 2.0, 3.0, 4.0…}
PSRemotingProtocolVersion 2.3
SerializationVersion 1.1.0.1
WSManStackVersion 3.0
Then use remoting to my Linux box:
PS C:\Windows\System32> Enter-PSSession -HostName 'linuxbox.localdomain' -UserName 'root'
root@linuxbox.localdomain's password:
[root@linuxbox.localdomain]: PS /root> $PSVersionTable
Name Value
---- -----
PSVersion 7.0.0
PSEdition Core
GitCommitId 7.0.0
OS Linux 5.4.28-1-lts PowerShell/PowerShell#1 SMP Wed, 25 Mar 2020 13:04:22 +0000
Platform Unix
PSCompatibleVersions {1.0, 2.0, 3.0, 4.0…}
PSRemotingProtocolVersion 2.3
SerializationVersion 1.1.0.1
WSManStackVersion 3.0
And then use TAB-completion on file-paths, it will append backslashes instead of forward slashes.
In this case, I typed /tm followed by TAB.
[root@linuxbox.localdomain]: PS /root> Set-Location -Path '/tmp\'
Powershell can, however deal with them, as I can keep typing and the next TAB will auto-correct the backslash to a forward slash.
In this case, I typed /tmp\scrip followed by TAB.
[root@linuxbox.localdomain]: PS /tmp> Set-Location -Path '/tmp/scriptroot\'
Pressing Enter on the above command also works fine with the backslash.
[root@linuxbox.localdomain]: PS /tmp/scriptroot>_
If I (as accurately as is possible) reproduce the steps involved in a Enter-PSSession over SSH by:
- Starting PwSh on Windows
- From there using the Windows OpenSSH client native to Win10 to connect to the Linux box
- And finish by starting pwsh manually from the default Linux shell
it works just fine:
PS C:\Windows\System32> ssh root@linuxbox.localdomain
root@linuxbox.localdomain's password:
Last login: Thu Apr 2 23:34:34 2020 from 192.168.xxx.xxx
root@linuxbox ~ # pwsh
PowerShell 7.0.0

Type 'help' to get help.
PS /root> Set-Location -Path '/tmp/'
PS /tmp> Set-Location -Path '/tmp/scriptroot/'
PS /tmp/scriptroot>
In other news, I notice the previous PSRemoting session isn't registered as a login session.
PS /tmp/scriptroot> last
root pts/0 192.168.xxx.xxx Fri Apr 3 20:02 still logged in
root pts/0 192.168.xxx.xxx Thu Apr 2 23:34 - 23:36 (00:01)
Linux security admins everywhere are blocking PwSh-over-SSH right now.
Expected behavior
Do you want me to write it out? Expected behavior is when TAB auto-complete appends forward slashes instead of backslashes. Which happens when running pwsh from the linux console, as well as when I connect using SSH into the default shell first, before starting pwsh from said shell.
My guess is it has something to do with the fact that the parent-session is Windows. But since Linux-native commands like ls (and as you can see last) work, it would mean that IsLinux should be $True. I'll leave it to the experts.
