replace text in file using wildcards
- 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.

Using the format you're looking for to calculate yesterday is a PAIN! Maybe there's an easier though.$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)
That should help you out...- 已標示為解答mnemonicator 2009年6月25日 上午 06:31

- 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.
yes, you are correct. i'll try to do this, it's my first steps in PS...
