Get return of cmd.exe exit

I develop a PowerShell application. I use for example

Start-Process "cmd.exe" "/c some_command"
#rest of the source code

But when I run this, it is not waiting for cmd.exe to close before executing the rest of the source code.

How can I get cmd.exe "exit event" return to continue to run my PowerShell script?

Or other way to sleep PowerShell script while cmd.exe is running?

In addition to using -Wait, you could also check the exit code to verify command success:

[int]$ExitCode = (Start-Process "cmd.exe" "/c some_command" -Wait).ExitCode

# Check exit code
if ($ExitCode -ne 0) {
    throw "Something went wrong.
}

This is useful for debugging and checking cmd success.

You can invoke CMD directly from PowerShell:

cmd.exe /c some_command

In case the executable is provided as a string rather than a bare word you must prefix the statement with the call operator (otherwise using the operator is optional):

& 'cmd.exe' /c some_command

This kind of invocation automatically runs synchronously.

Start-Process invocation is asynchronous by default. You can change the behaviour to synchronous by adding the parameter -Wait.

I found the answer is to use -wait

Start-Process "cmd.exe" "/c some_command" -wait
