This sample is a Windows batch file that uses a combination of environment variables set by the UEM Server and the current system date/time in an attempt to construct a unique file name used to store the output of the dir command. Because multiple instances of this script can be executing at the same time, and a process ID is not available to a Windows batch file, a loop exists to retry the file name construction if a matching file is found. |
