How to pass parameters to a batch file from Powershell

Question

I've tried multiple iterations of the following and nothing worked. The .bat file needs to accept 2 parameters. $IN and $TIC which are initials and ticket number.

Variables:

$IN = $textboxInitials.Text
$TIC = $textboxTicket.Text

Commands (None of these work):

start "\\Path\InstallOffice.bat" $IN $TIC
start "\\Path\InstallOffice.bat $IN $TIC"
start "\\Path\InstallOffice.bat" KL 562355
cmd.exe /C "\\Path\InstallOffice.bat" KL 562355
& "\\Path\InstallOffice.bat" $IN $TIC

This does work, but it is without parameters.

start "\\Path\InstallOffice.bat"

I am writing a program to install a bunch of programs after our standard build process so the helpdesk can pick and choose what needs installed. This is just the first command to be run, there will be a bunch after it as well, so powershell will need to wait for the .bat file to finish before moving on the the next command.

In your bat script are you referencing %1 as $IN and %2 as $TIC? Does your bat script run natively if you execute it from the cmd console, bypassing the PowerShell script? — rojo

Use Start-Process. You can pass arguments with -ArgumentList $A,$B,....

Additionally you can call it with -PassThru to receive the process object and call WaitForExit() on it.

Here's the msdn page.

With this small demonstration batch EchoArgs.cmd:

@Echo off&SetLocal EnableDelayedExpansion
Set Cnt=0
Echo:Args=%*
:loop
If "%~1" Neq "" Set /A Cnt+=1&Echo Arg!Cnt!=%1&Shift&Goto :loop

This slightly revised versions of your 5 commands:

$IN = 'KL'
$TIC = '562355'
$Bat = ".\EchoArgs.cmd"

Clear
"--Variant 1"
start -wait -NoNewWindow $Bat -args "$IN $TIC"
"--Variant 2"
start -wait  -NoNewWindow $bat "$IN $TIC"
"--Variant 3"
start -wait  -NoNewWindow $Bat "KL 562355"
"--Variant 4"
cmd.exe /C $Bat KL 562355
"--Variant 5"
& $Bat $IN $TIC

I get this sample output:

--Variant 1
Args=KL 562355
Arg1=KL
Arg2=562355
--Variant 2
Args=KL 562355
Arg1=KL
Arg2=562355
--Variant 3
Args=KL 562355
Arg1=KL
Arg2=562355
--Variant 4
Args=KL 562355
Arg1=KL
Arg2=562355
--Variant 5
Args=KL 562355
Arg1=KL
Arg2=562355
