ScheduledTask script

system · January 4, 2015, 10:09am

Hi Team,
I wrote the script to get the scheduled tasks from win7/2008/R2/2003 hosts as we don’t have have this cmdlet in these OSs.

Current Challenges:

When the screen size is very small (PS Console’s) then if I run the command then if the output won’t fits with in the screen then at the end of the column the data is showing like “…” which shouldn’t happen. It should behave like to show | auto enable the horizontal bars along with full Output
My next goal is to write the script to start the jobs for which I will pipe this command. what are the changes need to be done(if any in this script) for the below requirement.
Ex: Get-ScheduledTask HOSTNAME at24|Start-ScheduledTask
Where to add the syntax to update-formatdata in my script. Also I don’t want to hotcode the ps1xml file path. It should take automatically where my psm1 script is located when I do import-Module
In which places I need to improve my coding practices and logic’s as well.

Not sure what you’re asking for here but if I could guess you could try
```
Write-Output $out | Format-Table -AutoSize
```
Again I’m unclear as to what you’re trying to accomplish. Your example posits that you will query a machine for a task and if found will run that task immediately and then you say you would like to do this using jobs? Without more info all I can advise is using
```
Invoke-Command -Computername OYWAS1101 -File filetorun.ps1
```
and inside your file you query for the schtasks, isolate the “Taskname” data and execute it.
Sorry, not getting it again what’s the xml doc for? As for “hardcoding” the xml file path you could use the $PSScriptRoot environmental variable if you’re using Powershell 3.0+ to make the xml’s path variable relative to your script file.
The bulk of your script is using string manipulation tricks to filter the output of a simple schtasks.exe command. Why not just put the /tn parameter in to your original command since it uses the wildcard character too? Example:
```
$Output = schtasks.exe /query /s $ComputerName /tn $TaskName /V /FO CSV | ConvertFrom-Csv
```
Going further your param block instantiates $Taskname as a string array I assume because you were looking for a specific character in the array. Try using -contains when looking for characters in a string array it’s much easier. As for better string manipulation you should look into using RegEx or “Regular Expressions”. Dr. Tobias Weltner did an excellent PowerTips Monthly on Regex back in Nov 2013 [url]http://powershell.com/cs/media/p/29098.aspx[/url].

EDIT

I have found that even though the schtasks /query /? command says there is a /tn parameter it doesn’t work so go with what you got but I still think regex will simplify your code.

Thanks Neff. I will improve the code and will submit here again in clear.

Please post your updated code as attachment or link to GitHub, Pastebin, etc. Without indentation it is more difficult to read and to verify for best practices which include code formatting.

Thanks
