Multiple batch files

In the early days many batch files depended on the fact that calling a batch file would not return to the calling batch file. Changing that behaviour without additional syntax would have broken many systems like batch menu systems using batch files for menu structures. As in many cases with Microsoft, backward compatibility therefore is the reason for this behaviour.

By the way: if you do not have all the names of the batch files, you could also use for to do this it does not guarantee the correct order of batch file calls; it follows the order of the file system :. In the calling batch file you can react using. You are calling multiple batches in an effort to compile a program. I take for granted that if an error occurs: 1 The program within the batch will exit with an errorlevel; 2 You want to know about it.

This way all batches are called in order but will stop at any error, leaving the screen as it is for you to see any error message. When executing the script, it will call aaa. But if you don't want to wait for aaa. Yes, this is silly, it would make more sense if you could call it with foo. And you won't be able to execute other command after the last closing bracket.

In most of the cases it will be best approach - it does not create a separate process but has almost identical behaviour as calling a :label as subroutine. In MS terminology it creates a new "batch file context and pass control to the statement after the specified label.

The first time the end of the batch file is encountered that is, after jumping to the label , control returns to the statement after the call statement. This will spawn a child process that will have all the environment ot the calling bat. Less efficient in terms of resources but as the process is separate ,parsing crashes or calling an EXIT command will not stop the calling. Allows you more flexibility as the capability to start the scripts in separate window , to not wait them to finish, setting a title and so on.

By default it starts the. Unlike the other methods from now on the examples will use external of the CMD. WMIC utility will create completely separate process so you wont be able directly to wait to finish. Though the best feature of WMIC is that it returns the id of the spawned process:. Again starts it in completely separate environment i.

Offers some timeout between started scripts. Basic transaction capabilities i. Looking at your filenames, have you considered using a build tool like NAnt or Ant the Java version. You'll get a lot more control than with bat files. If you want to open many batch files at once you can use the call command. However, the call command closes the current bat file and goes to another.

If you want to open many at once, you may want to try this:. Hi Rania, Congrats! Thank you for sharing your experience. Made me smile! At the same time, it confirms that we really need to cloud-enable Honeybee to let users such as you explore computationally intense stuff without having to close batch files manually.

Good luck with your research. Very exciting, Rania! Thank you so much for sharing. We will definitely start putting in some capabilities to make it easier for running cloud simulations like this.

Thanks for sharing the info about your experience. Is there any update regarding more user-friendly ways of cloud simulations? Hi AryanShahabian , I believe mostapha is currently working on a user-friendly cloud-based solution. Continued use of the site after the effective date of a posted revision evidences acceptance.

Brian Knittel discusses commands that are particularly effective in batch files and provides some examples of three categories of especially useful batch files.
