Powershell script to create scheduled tasks from csv file

Question

I would like to use Powershell to create a couple of scheduled tasks, on a server. I have created the file from existing schedule's

I have loaded up the csv file, piped it to a select, and retreived all the info that I require from the csv file. However I am not sure on how to pass these results on to a external non powershell command.

Import-Csv .\listoftasks.csv | Select 'Run As User','RP','Scheduled Type','TaskName','Task To Run','Repeat: Every','Repeat: Until: Duration' 

What I would like to do is something like:

Import-Csv .\listoftasks.csv | Select 'Run As User','RP','Scheduled Type','TaskName','Task To Run','Repeat: Every','Repeat: Until: Duration' | schtasks /create /RU ....

Answer 1

Try using ForEach-Object:

Import-Csv .\listoftasks.csv | 
Select-Object 'Run As User','RP','Scheduled Type','TaskName','Task To Run','Repeat: Every','Repeat: Until: Duration' | 
ForEach-Object { Invoke-Expression "schtasks /create /RU ..." }

Also, be wary of the properties whose names contain spaces. You can access them like so if the name contains a space:

$_.'Run As User'

Answer 2

Posting the end result of the advice I received, hopefully somebody else can use it as well. :)

#Added a column to the csv with heading RP - contains the password if you have to use
#hardcoded account \ passwords and cant use the system accounts
