Hi, Florian:

Run "get-help get-eventlog -examples" in powershell. It shows 3
examples of get-eventlog. I suppose 2nd one maybe is what you want.
It's:

get-eventlog -newest 5 -logname application

This command displays the 5 most recent entries in the Application
event log.

And it is oddly undocumented.  Where'd you find this?

I can't speak as to where Shafik picked it up, but I can tell you that
using MOW's fabulous TabCompletion (powertab:
http://thepowershellguy.com/blogs/posh/pages/powertab.aspx) will give
you a list of all availble options

get-content -<tab>

I can't recommend this PoSH add-on enough :-)

Hmm, it is there on my XP SP2 system.  I also notice that your output does not
include the -Encoding or the -Delimiter parameters.

Yes I noticed that too but was zooming in on the topic on hand (the -wait
parameter). Wonder what introduces the discrepency (missing 3rd party or
develpment tools, including the full .NET SDK)?

forEach ($s in Get-Content my.txt -Wait) { echo $s }



doesn't work...
