The command line support in Event Log Crash Browser is very simple.
/export
The /export command takes one argument, a filename.
/export e:\crash.elcbl
eventLogCrashBrowser.exe /export e:\crash.elcbl
The above command line will cause the list of events normally displayed on the user interface to be written to the file e:\crash.elcbl
This file could then be inspected at a later date, on the same computer or a different computer.
