Running multiple commands simultaneously

Question

I have a script that will run open multiple cmd windows and run different php commands in each window. Unfortunately, my current code waits for the first set of PHP commands to finish before the second set of PHP commands starts, defeating the purpose of opening multiple windows.

Is it possible to run all sets of PHP commands in separate cmd windows simultaneously?

My current code:

start
cd c:\users\administrator\desktop\chps\chp1
php checker.php
start
cd c:\users\administrator\desktop\chps\chp2
php checker.php
start
cd c:\users\administrator\desktop\chps\chp3
php checker.php
start
cd c:\users\administrator\desktop\chps\chp4
php checker.php
start
cd c:\users\administrator\desktop\chps\chp5
php checker.php
start
cd c:\users\administrator\desktop\chps\chp6
php checker.php
start
cd c:\users\administrator\desktop\chps\chp7
php checker.php
start
cd c:\users\administrator\desktop\chps\chp8
php checker.php
start
cd c:\users\administrator\desktop\chps\chp9
php checker.php
start
cd c:\users\administrator\desktop\chps\chp10

Solution

start "" /d "c:\users\administrator\desktop\chps\chp1" php checker.php
start "" /d "c:\users\administrator\desktop\chps\chp2" php checker.php
start "" /d "c:\users\administrator\desktop\chps\chp3" php checker.php

In above code snippet:

• start command starts a separate Command Prompt window to run a specified program or command.
• /d switch specifies the startup directory for new Command Prompt.

You could ensure and force creating a new instance of the command interpreter (Cmd.exe) as follows:

start "" /d "c:\users\administrator\desktop\chps\chp1" cmd /C php checker.php
start "" /d "c:\users\administrator\desktop\chps\chp2" cmd /C php checker.php
start "" /d "c:\users\administrator\desktop\chps\chp3" cmd /C php checker.php
