Powershell: Using SCHTASKS in Powershell

In this post you will see how powerful powershell is in combination with external applications like SCHTASKS.exe.

First you have to create a CSV file like this:

The following one-liner imports the CSV file and creates a task on every server which is saved in the CSV file:

# Create a scheduled task on all the servers in *.csv
import-csv ".\*.csv" | % { schtasks /create 
/S $_.Name /SC DAILY /TN "Task_Name" 
/TR "program_or_script" /ST time /RU account}

The next one-liner imports the CSV file and will modify a scheduled task on every server which is saved in the CSV file:

# Change a scheduled task on all the servers in *.csv
import-csv ".\*.csv" | % { schtasks /change 
/TN "Task_Name" /S $_.Name 
/TR "program_or_script" /ST 23:05 /RU System }

The last one-liner imports the CSV file and will delete a scheduled task on every server which is saved in the CSV file:

# Delete a scheduled task on all the servers in *.csv
import-csv ".\*.csv" | % { schtasks /delete 
/tn "Task_Name" /f /s $_.Name }
