Description

I'm trying to work around a bug where -NoProfile -NoLogo is not respected (#1677) when using pwsh.exe (Core) and logging remotely in via SSH. The way I tried to do it was by using the following in the very beginning of my Microsoft.PowerShell_profile.ps1 profile.

function IsInteractive {
    $non_interactive = '-command', '-c', '-encodedcommand', '-e', '-ec', '-file', '-f'
    -not ([Environment]::GetCommandLineArgs() | Where-Object -FilterScript {$PSItem -in $non_interactive})
}
# No point of running this script if not interactive
if (-not (IsInteractive)) {
    exit
}
...

However, this doesn't seem to work with a remote SSH, because when using [Environment]::GetCommandLineArgs() with pwsh.exe, all you get back is:
C:\Program Files\PowerShell\6\pwsh.dll
regardless whether or not you are in an "interactive" session.

Any better ideas how to check if the profile is running from a remote SSH session?


UPDATE: Apparently the *.dll thing is a bug in .NET 5.0 as reported here.

Research direction

Start with the profile snippet using Microsoft.PowerShell_profile.ps1 and [Environment]::GetCommandLineArgs(), then review the referenced #1677 issue and the linked .NET 5.0 runtime report. The issue does not identify a target file, test, or agreed implementation, so completion criteria are not established.
