Different ways of sleeping/waiting in batch files

Posted by jpluimers on 2013/12/13

About a year and a half ago, I wrote about a Batch file to “Keep Alive” a CMAK generated VPN connection in Windows 7.

It uses ping to wait a certain amount of time, but it has the drawbacks of

  • requiring TCP/IP to be installed (which some headless systems don’t).
  • using N+1 as the number of seconds

Since then, I learned that since Windows Vista and up has timeout command that just waits:

timeout /t 600 /nobreak

Two parameters are used:

  • /nobreak
    does not stop waiting when you press a key
  • /t #
    waits # seconds

(the example is 10 minutes, I use it to regularly run FlushFileCache.exe or FlushMem.exe to empty the Windows file chache and release memory – often more than a gigabyte – back to Windows)

There is also sleep.exe, but that requires the Windows Resource Kit or Windows Server 2000/2003.

shorter version of batch file: getting directory and parent directory

Posted by jpluimers on 2013/08/17

Two years ago, I posted a batch file that gets the parent directory of the batch file that runs.

It was convoluted, using substrings and intermediate environment variables so you needed setlocal.

This one does not any more: for both the directory of the batch file, and the parent directory of that directory, one-liners suffice:

echo batchfile=%0
echo full=%~f0
for %%d in (%~dp0.) do set Directory=%%~fd
echo Directory=%Directory%
for %%d in (%~dp0..) do set ParentDirectory=%%~fd
echo ParentDirectory=%ParentDirectory%
