The token '&&' is not a valid statement separator in this version in vs code terminal

Question

I get an error when I try

 mkdir python && cd python && echo python > index.py

in my VS code terminal. This is the tutorial I am following.

I don't think we have chaining operators in PowerShell, you would need to use `;` instead (_which I'm not sure can be considered the same since chain is based of last exit code ?_) — Santiago Squarzon, Jan 03 '22 at 16:41

could you please check your PowerShell version using the following command

$PSVersionTable.PSVersion

As far I know, one of the new features of Powershell 7.0 is Pipeline chain operators: && and || so this should work only on powershell 7

Nice, I didn't know this was implemented in PS Core! – Santiago Squarzon Jan 03 '22 at 17:05

yes, I also thought that such a feature should be exist on powershell (it already exist on linux from decades ) and amazed that Microsoft made it on v.7 . – Mahmoud Moawad Jan 03 '22 at 17:13

Unfortunately I don't think we have such a thing as && chain operators in Windows PowerShell, would be nice though. This is pretty close to what you're looking for, it is a lot more verbose as you can see.

Note, mkdir is an alias for New-Item.

$folder = New-Item python -ItemType Directory
if($?){ Push-Location $folder; 'python' > index.py; Pop-Location }

Based on Mahmoud Moawad's answer, if you're running PowerShell Core:

New-Item python -ItemType Directory -Force 1>$null && Push-Location python && 'python' > index.py && Pop-Location

The token '&&' is not a valid statement separator in this version in vs code terminal
