Linux powershell command from terminal returns command not found

Question

I have a Linux box running Ubuntu Server 16.04 with Powershell on it, from the Linux terminal if I run:

sudo powershell (Invoke-Webrequest http://ipinfo.io/json | ConvertFrom-Json).ip

I get an error saying it is formatted incorrectly and expected a ')' at the end. if I remove the () and just try to convert from JSON it throws a could not find the command ConvertFrom-Json.

That said if I actually go into powershell and run the original command it works perfectly.

Any help would be greatly appreciated.

I figured it out need to wrap the command like this

sudo powershell '(Invoke-Webrequest http://ipinfo.io/json | ConvertFrom-Json).ip'

thank you for your help!

I haven't used PowerShell on Linux (yet), but on Windows you'd need

powershell -Command { (Invoke-WebRequest http://ipinfo.io/json | ConvertFrom-JSON).ip }

Thanks Jeff I just tried and I still get the -Bash syntax error near unexpected token '('

OK, I don't speak bash, but my next suggestion would involve doing whatever bash requires to escape the parens - perhaps \( and \)? You may also need to escape the | as well.
