I'm trying to use a powershell pipe to do the following which doesn't work. Has anyone got a suggestion on how I can do this in one step
$a = bcdedit /enum | select-string "identifier.*current" | $-.line
at the moment I'm needing to do the following
$aobj = bcdedit /enum | select-string "identifier.*current"
$a = $aobj.line
Is there a way I can combine this into one line?
The following should work provided you are pulling a single line from the BCDEDIT output:
$a = (bcdedit /enum | select-string "identifier.*current").line
If you might get multiple lines, the following will return an array of lines:
$a = bcdedit /enum | select-string "identifier.*current" | foreach-object { $_.Line }
Take you pick :)
If you want to get a property of an object by itself, the usual way to do it is with Select-Object -ExpandProperty.
bcdedit /enum | select-string "identifier.*current" | Select-Object -ExpandProperty Line

so I have a powershell command that grabs a registry key. But when using select-pattern, it always sticks the whole key within a line, and I've been googling everywhere but no where is telling me how to only grab certain language from the line, and not return the full like. Like below:
Line : #{t0_recursive=\\ad\; t7_recursive=\\ad\chrolit; t5_recursive=\\ad\arolit; t3_recursive=k:\;
t9_recursive=\\ad\fwrolit; t10_recursive=\\ad\larolit; t15_recursive=\\ad\slrolit;
t6_recursive=\\ad\brolit; t11_recursive=\\ad\mirolit; t14_recursive=\\ad\sfrolit;
t12_recursive=\\ad\nyrolit; t2_recursive=j:\; t16_recursive=\\ad\enfcases; t1_recursive=f:\;
t8_recursive=\\ad\drolit; t4_recursive=m:\; t13_recursive=\\ad\plrolit; t17_recursive=C:\ENFProcessing;
t129=c:\enfprocessing; t99=\\ad\slrolit; t9=\\ad\; t84=\\ad\sfrolit; t69=\\ad\plrolit; t54=\\ad\nyrolit;
t39=\\ad\mirolit; t279_recursive=C:\Users; t264=\\ad\fwrolit; t249=\\ad\drolit; t24=\\ad\larolit;
t234=\\ad\chrolit; t219=\\ad\brolit; t204=\\ad\arolit; t159_recursive=\\AD.SEC.GOV\Projects;
t144_recursive=\\AD.SEC.GOV\users; t114=\\ad\enfcases;
PSPath=Microsoft.PowerShell.Core\Registry::HKLM\SOFTWARE\Policies\Adobe\Adobe
Acrobat\DC\FeatureLockDown\cTrustedFolders\cAlwaysTrustedForJavaScript;
PSParentPath=Microsoft.PowerShell.Core\Registry::HKLM\SOFTWARE\Policies\Adobe\Adobe
Acrobat\DC\FeatureLockDown\cTrustedFolders; PSChildName=cAlwaysTrustedForJavaScript;
PSProvider=Microsoft.PowerShell.Core\Registry}
I get this output, but can't just return PSPath and the C:\Users* from the line, it always returns the full line.
Why is this?
$value = Get-ChildItem -Path 'Registry::HKEY_CURRENT_USER\SOFTWARE\Adobe\Adobe Acrobat\DC\TrustManger\cTrustedFolder' 2>NULL | findstr : | measure-object -line | select-object -expandproperty lines ; if ( $value -lt 1 ) { echo 'PASSED, HKEY_CURRENT_USER\SOFTWARE\Adobe\Adobe Acrobat\DC\TrustManger\cTrustedFolder is NULL' } else { $value2 = Get-ChildItem -Path 'Registry::HKEY_CURRENT_USER\SOFTWARE\Adobe\Adobe Acrobat\DC\TrustManger\cTrustedFolder' -Recurse | ForEach-Object {Get-ItemProperty -Path $_.PSPath -Name t*} |Select-String -Pattern 'c:\\users*' | select -ExpandProperty Line| findstr /i /V /c:Desktop, /c:downloads|format-list LineNumber,Line
I tried googling how to edit lines in powershell, to no avail.
Take out findstr. It turns objects to strings.
The get-childitem output is a bit confusing for the registry. The formatting file $PSHOME\Registry.format.ps1xml runs get-itemproperty. Use get-itemproperty to get registry values.
I have a replacement for get-itemproperty that can be used for recursive searches here: Use PowerShell to search for string in registry keys and values
For example:
get-childitem -recurse hklm:\software\adobe | get-itemproperty2 |
? name -like distiller*
Path Name Value Type

HKLM:\software\adobe\Acrobat Distiller\10.0\Uninstall Distiller 1 DWord
I'm a long time Bash enthusiast trying to get my bearings with Powershell. I'm trying to do something that could easily be accomplished with Awk, but I can't seem to find a solution in Powershell documentation. I'm essentially trying to select the third value from the output of the command delimited by /
Get-ADOrganizationalUnit -Properties CanonicalName -Filter * | Select-Object -ExpandProperty CanonicalName | Select-String ".*/Example/.*"
example.local/Example/ExampleOU1
example.local/Example/ExampleOU2
I just want to select the last value shown here. In Bash land this could easily be accomplished by an awk -F "/" '{print $3}' however I'm struggling to find the equivalent in Powershell. I found Out-String | %{ $_.Split('/')[2]; }' which is nice, but only works if there's one object. I'm assuming I need to ForEach-Object, then convert to a string, then split, but I'm not sure how.
I almost never use out-string. Canonicalname is a property of the object, so you need to reference that property. This would work:
[pscustomobject]#{canonicalname = 'example.local/Example/ExampleOU1'} |
% { $_.canonicalname.Split('/')[2] }
ExampleOU1
There's also -split which uses regex:
[pscustomobject]#{canonicalname = 'example.local/Example/ExampleOU1'} |
% { ($_.canonicalname -split '/')[2] }
Paths come up so often there's a command for it:
[pscustomobject]#{canonicalname = 'example.local/Example/ExampleOU1'} |
% { split-path -leaf $_.canonicalname }
I'm trying to compile log errors from multiple files in a single directory. The error messages are included over the span of two lines. I would like to concatenate both lines into a single line/object and then export all errors into a a neat csv.
I'm attempting to accomplish this with the Select-String utility, and the -Context parameter. Prior to piping the results through the Select-Object utility, everything's Kosher. However, Once I pipe the results through Select-Object or Export-CSV, the -Context line is lost.
$trigger = 'ERROR'
$folderPath = 'C:\Users\test\Desktop\testpath'
$logFiles = gci -Path $folderPath -Filter *.txt -File
$logFiles | Select-String -Pattern $trigger -CaseSensitive -SimpleMatch -Context 0,1 | Select-Object LineNumber, Line, Filename |
Export-Csv -Path .\$(Get-Date -Format yyyymmddhhmmss).csv -Encoding UTF8 -NoTypeInformation
Omitting the Select-Object and Export-Csv Cmdlets yields the desired, raw, results with the friendly right angle bracket '>' (ASCII 62). The raw results can even be exported via the Out-File Cmdlet, no problem.
However, what I would like to do, is combine the Pattern line with the Context line, creating a single object, which would eventually be output as a csv for further analysis.
I would like apologize if this question seems trivial. I've scoured resources trying to figure this out and unfortunately haven't been able to. Thanks in advance!
Pipe select-string through fl * to see what the properties are.
$a = ls log | select-string error -context 0,1
$a | fl *
IgnoreCase : True
LineNumber : 2
Line : error
Filename : log
Path : /Users/js/log
Pattern : error
Context : Microsoft.PowerShell.Commands.MatchInfoContext
Matches : {0}
$a.context
PreContext PostContext DisplayPreContext DisplayPostContext
---------- ----------- ----------------- ------------------
{} {after } {} {after }
This worked for me:
ls log | select-string error -context 0,1 | select linenumber, line,
#{n='PostContext'; e={$_.context.postcontext}}, filename
LineNumber Line PostContext Filename
---------- ---- ----------- --------
2 error after log
Code:
$adgroups = Get-ADPrincipalGroupMembership $tag$ | select -ExpandProperty Name | Sort | Select-String "iSite"
Output:
DFSR Managed iSite Enterprise 4.4.542.2 WSA_Rad_A
DFSR Managed iSite Radiology 4.4.516.27 WSA_Rad_A
Basically one command generates two items (output using $variable | out-file C:\file.txt -Append) and when I go to open these in excel they format as one line like this:
DFSR Managed iSite Enterprise 4.4.542.2 WSA_Rad_A DFSR Managed iSite Radiology 4.4.516.27 WSA_Rad_A
Is there a way to break it up // add a new line after each item but still keep them both inside one variable?
Get-ADPrincipalGroupMembership $tag$ | select -ExpandProperty Name | Sort | Select-String "iSite" | ConvertTo-Csv -NoTypeInformation | Out-File C~\Desktop\Sites.csv
I would break up your request a bit.
First, you're using Select -Expand, which is going to discard all of the properties and only return the values for each object's Name. This is a problem because when you export it as a CSV, you're not going to have a heading. I think the lack of header is ultimately leading to the issue you're facing here.
Try this instead:
$adgroups = Get-ADPrincipalGroupMembership $tag$ | Where Name -like "*iSite*" |
select Name | Export-Csv c:\pathto\YourCsv.Csv
Finally, I don't think Select-String is doing you any favors. You could instead use the -like operator.
I have an XML command that returns a list of URLs, example
PS > $xml.rss.channel.item.link
http://example.com/20140704.exe
http://example.com/20140704.tar.xz
http://example.com/20140624.exe
http://example.com/20140624.tar.xz
http://example.com/20140507.tar.xz
From this list, I would like to return the first .tar.xz line. I have this
command
$xml.rss.channel.item.link | ? {$_ -match '.tar.xz'} | select -first 1
But I would prefer a command with only one pipe if possible.
You don't need a pipe at all:
(Select-Xml -Xml $xml -XPath "(//link[contains(.,'.tar.xz')])[1]").Node.InnerText
Note: XPath is case-sensitive. If that is an issue, you can use a trick with translate() function and force it to ignore the case.
A different way using two pipes
$xml.rss.channel.item.link | Select-String .tar.xz | select -first 1
One pipe
($xml.rss.channel.item.link | Select-String .tar.xz)[0]
