I have the need to mark the time in some logs that are created by powershell scripts. I use

$date = get-date

The first time the $date variable is used, the date is correct. Iterations following all have the same date. How can I clear the $date variable so that every time I call it, the current date is used?

clear-variable $date shows error shown:
Clear-Variable : Cannot find a variable with name '03/28/2014 17:19:13'.

Just set date to null at the end of each iteration


#Start of loop
$date = Get-Date


End of loop
$date = $null

Instead of assigning the results of Get-Date to a variable, if you're not going to use that variable again, just call Get-Date where you need it.

For example
"start time -- $(Get-Date)" | Add-content file.txt

Footech has the right idea.  Just replace all occurrences of $date with (get-date).

But if you want to use Clear-Variable, the correct way to do it is:
Clear-Variable 'Date'

Open in new window

Both of the guys above are right unless you are trying to do something midstream in your flow which cause you to get an error when calling Get-Date.

Having an idea of the snippet of code you are trying to fix would help.

Since you indicate clear variable gives you and error you can simply go for:
#Start of loop
$date = $null 
$date = Get-Date

Open in new window


#Do stuff
