I am writing a powershell interpreter that looks at Malware. And I have some text I don't know how to parse. It looks like a pipeline but what comes after the pipe doesn't make sense to me and the interpreter I am modifying doesn't not handle. The relevant statement is shown below.

```
start-process($env:APPDATA+ '\mef.vbs')|I`E`X

```

I get the start-process part. It's just the pipe I don't grok. `E might be an backtick for escape, but `X isn't in any documentation I have seen. Moreover, it doesn't look like a command to process the output from the "start-process". So, what is "|I`E`X"?
