Vista - Using PowerShell to handle Eventlog

Hello,
my idea is as follows (basically to play & learn with Powershell):



* Running a daily powershellscript at night which:
** Exports all entries in a file
** Delete all entries

Ok i could use somethnig like this to list all System-Event Entries
and write them to log:orto have only the latest

Now i am asking myself howto delete all entries in the second step.

any ideas how to handle this ?


Best regards
fidel

Ok,

i can use this:to dump all system-related informations in my text file


and i can use this:to delete the event logs completly


Now regarding the filename:
--
i.e.
i would like to end with files like that:
* 20080415_hostname_logtype.txt (execution_date + hostname + here:
system


Best regards

I am not aware of any way that you can selectively delete entries like
this. You can export your entire log, parse the export, delete the
entries you want, then re-import it. But... This method can only be
re-imported, to my knowledge, to a *new* log name, and can't be
re-imported into the default/original log. For example, I can't export
the Security log, delete it, then re-import what I just exported back to
the Security log.

I wouldn't start editing the binary log either...
