The following is a PowerShell Job Scheduling Script able to read a PowerShell script from a file and schedule it to run once, daily or weekly (while indicating which days of the week are selected). The script collects the options indicated by the user, assembles a commandlet, submits it to the user for review and executes it upon approval.
#How to register a Scheduled Job directly from Powershell
#If you do not run Powershell 3.0 please remove the -message parameter in the Get-credential command in the $scheduletask variable
Write-Host “`r`nSchedule An AppAssure Task Using Powershell`r`n——————————————-`r`n”
#default code location; make sure to add a semicolon at the end of each row.
$dfile = “c:\code.txt”
#Set New Job Name
$JobName = Read-Host “Choose a name for the Scheduled Job`r`nStart all Job Names with AppAssure i.e. Appassure Task 1;`r`nno quotation marks, please”
#Credentials for the Scheduled Job
# $cred = get-credential [will be performed at the time the task is scheduled]
$message = ‘ -message “Enter the User Name (domain\user) and Password under which the task will run”‘
#If you do not run Powershell 3.0 please remove the -message parameter in the $schedtask variable
