What does the & symbol in powershell mean?

Question

``` $tool = 'C:\Program Files\gs\gs9.07\bin\gswin64c.exe' & $tool -q -dNOPAUSE -sDEVICE=tiffg4 $param -r300 $pdf.FullName -c quit ``` Can someone explain to me how the this works? What exactly does the & symbol do/mean in powershell?

Accepted Answer

`&` is the call operator which allows you to execute a command, a script, or a function. For more details: SS64 documentation: Call operator (&) Microsoft Docs: Call operator &

```
Syntax
      & "[path] command" [arguments]
```

Example:

```
$LocalComputerName = & $ENV:windir\System32\HostName.exe
```

Also, if you use an IDE (such as `PowerGUI`) you can block it from opening a separate window when executing a secondary process:

```
& more
Start-Process "my_script.here"
```
