Embedded PowerShell Scripts

[Nathan_K]

Hey Glenn,

I’m trying to use the SET-CONTENT feature to pull a script inside of the INI, but I can’t seem to pass an argument to the embedded script like I can with an external call. Any thoughts?

Thanks!

[Glenn]

you can’t just add it to the parameters option?

Here is my code block from the config. You can see the result in the attached screenshot.

CMD=interval:10,text:Local Fixed Disks,read-as-csv:1,csv-header:1,file:powershell.exe,parameters:.\scripts\BitLocker-Status.ps1 -query "Local Fixed",trim:1,show-window:0,color:ffbb77,chart:bar2 scale:linear max:100 series1:{{((%Size%-%FreeSpace%)/%Size%)*100}} threshold:90 0000FF,hide-no-result:1,display:%Name% {{%Size%-%FreeSpace%}}[1.0b]B / {{%Size%}}[1.0b]B ({{((%Size%-%FreeSpace%)/%Size%)*100}}[1.0d]% used) %chart%| BitLocker Status: %BitLocker%

That calls the external PS1. If I use the same line and replace the PS1 with my SET-SECTION variable, I get no output data. If I hard code “Local Fixed” into the PS block, I get all bad data.

Here is my “SET-SECTION” block.

SET-SECTION=key:bitlocker-status,value:bitlocker-status.ps1 CMD=interval:10,text:Local Fixed Disks,read-as-csv:1,csv-header:1,file:powershell.exe,parameters:%bitlocker-status% -query "Local Fixed",trim:1,show-window:0,color:ffbb77,chart:bar2 scale:linear max:100 series1:{{((%Size%-%FreeSpace%)/%Size%)*100}} threshold:90 0000FF,hide-no-result:1,display:%Name% {{%Size%-%FreeSpace%}}[1.0b]B / {{%Size%}}[1.0b]B ({{((%Size%-%FreeSpace%)/%Size%)*100}}[1.0d]% used) %chart%| BitLocker Status: %BitLocker%

This has taken me all day to figure out!! I must be getting old 😐

I’m adding one extra user variable before the CMD which contains the query type LOCAL FIXED or REMOVABLE. This is referenced inside the actual embedded script.

INI

SET-SECTION=key:bitlocker-status,value:bitlocker-status.ps1 SET=key:script_query,value:LOCAL FIXED CMD=interval:10,text:Local Fixed Disks,read-as-csv:1,csv-header:1,file:powershell.exe,parameters:%bitlocker-status%,trim:1,show-window:0,color:ffbb77,chart:bar2 scale:linear max:100 series1:{{((%Size%-%FreeSpace%)/%Size%)*100}} threshold:90 0000FF,hide-no-result:1,display:%Name% {{%Size%-%FreeSpace%}}[1.0b]B / {{%Size%}}[1.0b]B ({{((%Size%-%FreeSpace%)/%Size%)*100}}[1.0d]% used) %chart%| BitLocker Status: %BitLocker%

1 2 3

SET-SECTION=key:bitlocker-status,value:bitlocker-status.ps1 SET=key:script_query,value:LOCAL FIXED CMD=interval:10,text:Local Fixed Disks,read-as-csv:1,csv-header:1,file:powershell.exe,parameters:%bitlocker-status%,trim:1,show-window:0,color:ffbb77,chart:bar2 scale:linear max:100 series1:{{((%Size%-%FreeSpace%)/%Size%)*100}} threshold:90 0000FF,hide-no-result:1,display:%Name% {{%Size%-%FreeSpace%}}[1.0b]B / {{%Size%}}[1.0b]B ({{((%Size%-%FreeSpace%)/%Size%)*100}}[1.0d]% used)   %chart%|   BitLocker Status: %BitLocker%

That user variable is added to the embedded script:

PowerShell

$query='%script_query%' If ( -not $query ) { Exit 1 } ...

1 2 3

$query='%script_query%' If ( -not $query ) { Exit 1 } ...

the rest of the script requires you to get the quote characters correct. For the most part, the single quote character seems to work. Hopefully the following code displays correctly on the forum:

this shows the standard disk display on the top and your display underneath.

I think most of my issues were the single vs double quotes. I did figure out how to set the query inline as well.

parameters:-Command "& {$query='Local Fixed'; %bitlocker-status%}"

That seems to work correctly.
