(cross posted on stack overflow)

According to pwsh documentation, I should be able to pass command-line arguments but I am getting errors instead (both from a PS prompt and from a CMD prompt):

> pwsh -NoExit
-NoExit : The term '-NoExit' is not recognized as the name of a cmdlet, function, script file, or operable program.
...

> pwsh -NoLogo
-NoLogo : The term '-NoLogo' is not recognized as the name of a cmdlet, function, script file, or operable program.
...

> pwsh -h
-h : The term '-h' is not recognized as the name of a cmdlet, function, script file, or operable program.
...

> pwsh -Command "Write-host hello"
-Command : The term '-Command' is not recognized as the name of a cmdlet, function, script file, or operable program.
...

But this works:

> pwsh "Write-host hello"
hello

My pwsh version is 6.2.3.0

What is going on???

Did you try to run the pwsh executable with its complete path?

3

Yes, it looks like your installation is broken, please reinstall and check to see if it’s working.

Also, try using ‘/’ instead of ‘-’

[pre]> pwsh /nologo[/pre]

Thank you.

4

Why that? What difference would it make if the executable in front of the argument isn’t found?

5

Yeah I know, you are right, but just in case, that’s it.

6

Are you running the executable or a .bat file?

7

what is it showing when you do ?

pwsh --help
pwsh /?

It should give the possible options to use with it.

Nope:

PS> C:\Users\ericj\.dotnet\tools\pwsh.exe --help
At line:1 char:3
+ --help
...
Unexpected token 'help' in expression or statement.

PS> C:\Users\ericj\.dotnet\tools\pwsh.exe /?
/? : The term '/?' is not recognized as the name of a cmdlet, function, script file, or operable program.

PS> C:\Users\ericj\.dotnet\tools\pwsh.exe "write-host hello"
hello

Uninstalling and reinstalling did not work:

PS> dotnet tool uninstall --global PowerShell
Tool 'powershell' (version '6.2.3') was successfully uninstalled.
PS> pwsh

I don’t know what this is. I get powershell core here: GitHub - PowerShell/PowerShell: PowerShell for every system!
