Hi there, i have next text in my file *20090623* this is date, i need change this text every day, so i wrote next code

$getdate_curr=get-date -format yyyMMdd (assign to variable current date in required format) and then i'm trying replace old date to new one

(Get-Content D:\I\moveit\config.par) |
Foreach-Object {$_ -replace "2009*\*",$getdate_curr} |
Set-Content D:\I\moveit\config.par

It's work incorrectly, how can i change this code?

Thank you.

Are you always replacing the date from the day before? I'm thinking you would create a variable for yesterday and today, and then use those variables in the replace to do an exact replacement.

Check this out:

$today=get-date -format yyyMMdd

$today

$yesterday=(get-date).adddays(-1)|%{
  if($_.month -lt 10){$month=[string]0+$_.month}else{$month=$_.month}
  if($_.day -lt 10){$day=[string]0+$_.day}else{$day=$_.day}
  [string]$_.year+[string]$month+[string]$day
}

$yesterday

"$yesterday".replace($yesterday,$today)

Using the format you're looking for to calculate yesterday is a PAIN! Maybe there's an easier though.

That should help you out...
