Powershell script to create scheduled Task with argument

Question

i have this Script which is checking if a named service is running. In the actual case its checking for "RSCDsvc" service.

if(!(Get-ScheduledTask | Where-Object {$_.TaskName -like "restart_RSCDsvc" })){ New-Item -Path C:\Admin\scripts -Name check-service.cmd -Force -ItemType "file" -Value ' @ECHO OFF SET SvcName=%~1 SC QUERYEX "%SvcName%" | FIND "STATE" | FIND /v "RUNNING" > NUL && ( ECHO %SvcName% is not running ECHO START %SvcName% NET START "%SvcName%" > NUL || ( ECHO "%SvcName%" wont start EXIT /B 1 ) ECHO "%SvcName%" is started EXIT /B 0 ) || ( ECHO "%SvcName%" is running EXIT /B 0 ) ' $dt= ([DateTime]::Now) $timespan = $dt.AddYears(33) -$dt; $principal = New-ScheduledTaskPrincipal -UserID "NT AUTHORITY\SYSTEM" -LogonType ServiceAccount -RunLevel Highest $Action = New-ScheduledTaskAction -Execute C:\Admin\scripts\check-service.cmd -Argument "RSCDsvc" $Trigger = New-ScheduledTaskTrigger -Once -At (Get-Date).Date -RandomDelay (New-TimeSpan -Minutes 5) -RepetitionDuration $timespan -RepetitionInterval (New-TimeSpan -Minutes 10) $Task = New-ScheduledTask -Action $Action -Trigger $Trigger -Settings ($Stset = New-ScheduledTaskSettingsSet -ExecutionTimeLimit (New-TimeSpan -Minutes 3)) -Principal $principal $Task | Register-ScheduledTask -TaskName ‘restart_RSCDsvc’ } 

Now my question would be if i can work with more arguments so i dont have to enter the specific Service name so often in the script. Now i have to set it at 3 different points

if(!(Get-ScheduledTask | Where-Object {$_.TaskName -like "restart_RSCDsvc" }))

$Action = New-ScheduledTaskAction -Execute C:\Admin\scripts\check-service.cmd -Argument "RSCDsvc"

$Task | Register-ScheduledTask -TaskName ‘restart_RSCDsvc’

Like ive said my goal would be to have something like "$Servicename = RSCDSVC" and then its set for this three lines. I have tried it already but im already proud i got this script finish as im not very good in scripting :(

You can just replace all instances of RSCDSVC with the variable name just like you theorized

$Servicename = "RSCDSVC" if(!(Get-ScheduledTask | Where-Object {$_.TaskName -like "restart_$Servicename" })){ New-Item -Path C:\Admin\scripts -Name check-service.cmd -Force -ItemType "file" -Value ' @ECHO OFF SET SvcName=%~1 SC QUERYEX "%SvcName%" | FIND "STATE" | FIND /v "RUNNING" > NUL && ( ECHO %SvcName% is not running ECHO START %SvcName% NET START "%SvcName%" > NUL || ( ECHO "%SvcName%" wont start EXIT /B 1 ) ECHO "%SvcName%" is started EXIT /B 0 ) || ( ECHO "%SvcName%" is running EXIT /B 0 ) ' $dt= ([DateTime]::Now) $timespan = $dt.AddYears(33) -$dt; $principal = New-ScheduledTaskPrincipal -UserID "NT AUTHORITY\SYSTEM" -LogonType ServiceAccount -RunLevel Highest $Action = New-ScheduledTaskAction -Execute C:\Admin\scripts\check-service.cmd -Argument "$Servicename" $Trigger = New-ScheduledTaskTrigger -Once -At (Get-Date).Date -RandomDelay (New-TimeSpan -Minutes 5) -RepetitionDuration $timespan -RepetitionInterval (New-TimeSpan -Minutes 10) $Task = New-ScheduledTask -Action $Action -Trigger $Trigger -Settings ($Stset = New-ScheduledTaskSettingsSet -ExecutionTimeLimit (New-TimeSpan -Minutes 3)) -Principal $principal $Task | Register-ScheduledTask -TaskName "restart_$Servicename" }
