Running a program from within a batch script, CMD.EXE will pause the initial script and wait for the application to terminate before continuing.

The START command without the /B parameter opens the program or command in a new window. On the command line, CMD.EXE does not wait for the application to terminate and control immediately returns to the command prompt. The meaning with my somwhat cryptic post whas to get either a better way to use RunOnceEx to call those commands directly OR find that other method where callings those batches. I use WPI and feels it's a waste of nice coding not to use provided commandlines and use a single batchfile instead. Even if there are multiple commands, /wait can be used for each process to finish and move to the next one.Īlso, the parameter /B is used to stay in the same process without creating a new window. thats why I used 'cmd /c start' to call cmd first. When we start a program in a Batch file using the START command, we can wait until the program is finished by adding /wait to the START command. Use /WAIT to Wait for a Command to Finish Execution This tutorial illustrates different ways to wait for a command or a program to finish before executing the next command. Instead of starting a command, if there is a need to insert delays in the Batch file for some time interval, we can use commands such as TIMEOUT and PAUSE to stop the execution of the next process for a short interval of time or until a key is pressed. For a process to wait until it is finished, we use the /wait parameter with the START command. It is important to make those commands wait for them to finish and then execute the next commands. But when a Batch file is run, it does not wait for a command process to finish it executes all commands line by line. There are multiple commands and installation processes in a Batch file that usually take some time to complete. Could you test again Harry Johnston at 22:03 Add a comment 1 Answer Sorted by: 14 This appears to be a bug in the implementation of the start command. Use the PAUSE Command to Pause the Execution The start command ignores the /wait option if it is followed by /b, e.g., start /wait /b notepad won't wait.Use the TIMEOUT Command to Delay the Execution.Use /WAIT to Wait for a Command to Finish Execution.

Cmd c start wait
