Mostly No one have interest to wait for some time to complete the work/task/execution.But in certain situation, that’s is not always possible to completed the task without waiting for few seconds/Minutes. In Powershell if you wrote some automation and if sometimes it will to be take more time to execution due to gathering lot of information from then, reality, the script will take a time to complete.
In this scenario the script writer need to show some progress bar to indicate the user about the progress instead of blinking cursor at the delay. This can be achievable by using Write-Progress cmdlet which Displays a progress bar within a Powershell command window.
Syntax:
|
1 2 3 4 5 6 7 8 9 10 11 |
Write-Progress [-Activity] <String> [[-Status] <String>] [[-Id] <Int32>] [-PercentComplete <Int32>] [-SecondsRemaining <Int32>] [-CurrentOperation <String>] [-ParentId <Int32>] [-Completed] [-SourceId <Int32>] [<CommonParameters>] |
Example:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 |
