Question

Is there a verbose exact equivalent for the ‘&’ call operator to use with scriptblocks?

Like this pseudocode:

CALL { "Arguments are:"; $args; } One Two "Three word argument"

To replace:

& { "Arguments are:"; $args; } One Two "Three word argument"

EDIT:

The reason I need this is to pass batch file arguments to powershell.
This fails:

@ECHO OFF
START powershell.exe -noexit -Command "^& { \"Batch file arguments are:\"; $args; } %*"

I can do it like this, but the first method is cleaner:

@ECHO OFF
START powershell.exe -noexit -Command Invoke-Expression $('^& { \"Batch file arguments are:\"; $args; } %*')

I know I still need to escape quotes for long arguments.

Thanks.

You can pass batch file arguments to PowerShell like this:

@ECHO off
SETLOCAL
SET PS_ARGS=%*
IF DEFINED PS_ARGS SET PS_ARGS=%PS_ARGS:"=\"%
START powershell.exe -NoExit -Command "& { \"Batch file arguments are:\"; $args; } %PS_ARGS%"

It will escape quotes so you can call it like:

MyBatch.bat one two "Three word argument"
