I'm writing a Powershell script and in it I'm using a hash table to store information about database checks. The table has 5 keys (host, check, last execution time, last rep, status) and I want to search in my table for values where:
$s = $table where $host -eq $hostname -and check -eq $check
Does anyone have any idea how this is done? And if it makes any difference, the script cannot rely on .NET framework higher than 2.0
I´m new to Powershell and scripting in general so this might be very obvious but I still can't seem to find an answer on Google. Also if someone knows a good reference page for Powershell scripting I would really appreciate a link.

EDIT: Don't see how it matters but here is a function I use to create a hash table:
function read_saved_state{
$state = #{}
$logpos = #{}
$last_log_rotate = 0
foreach($s in Get-Content $saved_state_file){
$x = $s.split('|')
if($x[0] -eq 'check'){
$state.host = $x[1]
$state.check = $x[2]
$state.lastexec = $x[3]
$state.lastrep = $x[4]
$state.status = $x[5]
}
elseif($x[0] -eq 'lastrotate'){
$last_log_rotate = $x[1]
}
elseif($x[0] -eq 'log'){
$logpos.lastpos = $x[3]
}
}
$saved_state_file has one line for each check run and can also have a line for last log rotate and last log position. There can be as many as 12 checks for one host.
I'm trying to extract a particular check, run at a particular host, and changing the lastexec_time, last_rep and status.
return $state,$logpos,$last_log_rotate
}
Assuming you have an array or list of hashtables (not entirely clear from the question), your syntax is pretty close:
$s = $tables | where {($_.host -eq $hostname) -and ($_.check -eq $check)}

I am running a script that gives me Azure AD apps with its secret end date property. The property name which gives me all details in Azure AD is “PasswordCredentials” and I am using get-azureadapplication cmdlet.
What is the best way to check If the app has end date value within a month and filter on it, I tried where-object with get-date.adddays(30) and tried to compare with -lt operators.
Appreciate your support here.
Well, in your case, you should note there may be several PasswordCredentials for one app, so you need to use a loop to check every PasswordCredential.
And the EndDate you got from the Get-AzureADApplication command is a UTC time, but Get-Date returns the local time, so you need to use (Get-Date).AddDays(30).ToUniversalTime() instead of (Get-Date).AddDays(30). Also, if you just want to check the expiring ones, you must exclude the ones that have expired, so use $PasswordCredential.EndDate -gt $nowdate like below.
As you did not give your script, I can just give a sample for you, my sample is for a single app, if you want to check all the apps in your tenant, use a loop to do that.
$PasswordCredentials = (Get-AzureADApplication -ObjectId <object-id>).PasswordCredentials
$nowdate = (Get-Date).ToUniversalTime()
$wantdate = (Get-Date).AddDays(30).ToUniversalTime()
foreach($PasswordCredential in $PasswordCredentials){
if($PasswordCredential.EndDate -lt $wantdate -and $PasswordCredential.EndDate -gt $nowdate){
$keyid = $PasswordCredential.KeyId
Write-Output "The key with KeyId $keyid will expire"
}
}
Update:
If you want to get the AppId and AppName, you could use the script below.
$apps = Get-AzureADApplication -All $true
$nowdate = (Get-Date).ToUniversalTime()
$wantdate = (Get-Date).AddDays(30).ToUniversalTime()
foreach($app in $apps){
$PasswordCredentials = $app.PasswordCredentials
$appid = $app.AppId
$displayname = $app.DisplayName
foreach($PasswordCredential in $PasswordCredentials){
if($PasswordCredential.EndDate -lt $wantdate -and $PasswordCredential.EndDate -gt $nowdate){
$a = $app | select #{Name="AppId"; Expression={$appid}}, #{Name="DisplayName"; Expression={$displayname}}, #{Name="EndDate"; Expression={$PasswordCredential.EndDate}}
Write-Output $a
}
}
}
Using invoke-sql I have a PowerShell script that returns results from a SQL Query. That query has the status of several data points local I want to colour code the entire row if the column of Status returns different values. Is this possible as I know you can colour code Charts in PowerShell but not sure how a larger return query would work?
param(
[string] $dataSource = "SQLName",
[string] $database = "DatabaseName",
[string] $sqlCommand = $("Select tbldatafeed.datafeed_name,REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(tbldatafeedhistory.status_id,1,'Running'),2,'Completed'),3,'Faulted'),4,'Warning'),5,'Terminating'),6,'Terminated'),7,'Pending') AS Status,DateDiff(MINUTE,tbldatafeedhistory.start_time, tbldatafeedhistory.end_time) As 'Run Time(minutes)'
from tblDataFeedHistory
left Join tblDatafeed on tbldatafeedhistory.datafeed_id = tbldatafeed.datafeed_id
inner join
(
Select max(start_time) as LatestDate, [datafeed_id]
from tblDataFeedHistory
Group by datafeed_id
) SubMax
on tblDataFeedHistory.start_time = SubMax.LatestDate
and tblDataFeedHistory.datafeed_id = SubMax.datafeed_id
WHERE tbldatafeed.is_active = 1
Order by tbldatafeed.datafeed_id")
)
$connectionString = "Data Source=$dataSource; " + "Integrated Security=SSPI; " + "Initial Catalog=$database"
$connection = new-object system.data.SqlClient.SQLConnection($connectionString)
$command = new-object system.data.sqlclient.sqlcommand($sqlCommand,$connection)
$connection.Open()
$adapter = New-Object System.Data.sqlclient.sqlDataAdapter $command
$dataset = New-Object System.Data.DataSet
write-output $adapter.Fill($dataSet) | Out-Null
$connection.Close()
$dataSet.Tables
}
$FeedID = Invoke-SQL
$FeedID
The output would be a red highlighted line if the column returned Failed, yellow if the Column returns Warning, Green if the column returns Completed.
I've not personally found or seen a reason to do this with SQL data generally, nor do I have any record in my stash of anyone who has.
Anything you write to the screen can have color. It's one of the primary focuses of the …
[Write-Host][1]
Or
[Console]::ForegroundColor]
... cmdlet or .Net class.
However, if you plan to use that data on the pipeline, or elsewhere, then don't use it. Especially if you are not on the newest PowerShell versions. Legacy PowerShell, Write-Host empties the buffer, later PowerShell versions, send it to the Information Stream. As talked by PowerShell inventor Jeffery Snover here:.
http://www.jsnover.com/blog/2013/12/07/write-host-considered-harmful
... Jeffrey Snover change his stance on this as of May 2016.
With PowerShell v5 Write-Host no longer "kills puppies". data is
captured into info stream ...

However, there are PowerShell modules you can leverage to get really creative with color.
Find-Module -Name '*color*' | Format-Table -AutoSize
You also have several scripts to leverage as is or tweak for your use case.
Format Table Colors in PowerShell
Format the output table colors in PowerShell host with/without conditional colorful formatting.
Download : Write-PSObject.ps1
You do have another option. If you want to call attention, with color to a given screen output line, you can use the ...
Write-Warning
Write-Error
... cmdlets and just accept its default color.
Yet, your question could almost be a duplicate of these Q&A and its accepted answer.
Powershell - Output Color for certain results
Is there a way to specify a font color when using write-output
If you are saying, that you are sending this to a form, then you have to handle color in the form properties code.
Here I found a solution for the manual creation of the data seeding script. The manual solution allows me to select for which tables I want to generate the inserts
I would like to know if there is an option to run the same process via PowerShell?
So far I have managed how to create a SQL script which creates the Database schema seeder:
[System.Reflection.Assembly]::LoadWithPartialName('Microsoft.SqlServer.SMO') | out-null
$s = new-object ('Microsoft.SqlServer.Management.Smo.Server') "(localdb)\mssqlLocalDb"
$dbs=$s.Databases
#$dbs["HdaRoot"].Script()
$dbs["HdaRoot"].Script() | Out-File C:\sql-seeding\HdaRoot.sql
#Generate script for all tables
foreach ($tables in $dbs["HdaRoot"].Tables)
{
$tables.Script() + "`r GO `r " | out-File C:\sql-seeding\HdaRoot.sql -Append
}
however is there any similar way to generate the data seeding script?
Any ideas? Cheers
You can use the SMO scripter class. This will allow you to script the table creates as well as INSERT statements for the data within the tables.
In my example I'm directly targeting TempDB and defining an array of table names I want to script out rather than scripting out every table.
Scripter has a lot of options available, so I've only done a handful in this example - the important one for this task is Options.ScriptData. Without it you'll just get the schema scripts that you're already getting.
The EnumScript method at the end does the actual work of generating the scripts, outputting, and appending the script to the file designated in the options.
[System.Reflection.Assembly]::LoadWithPartialName('Microsoft.SqlServer.SMO') | out-null
## target file
$outfile = 'f:\scriptOutput.sql'
## target server
$s = new-object ('Microsoft.SqlServer.Management.Smo.Server') "localhost"
## target database
$db = $s.databases['tempdb']
## array of tables that we want to check
$tables = #('Client','mytable','tablesHolding')
## new Scripter object
$tableScripter = new-object ('Microsoft.SqlServer.Management.Smo.Scripter')($s)
##define options for the scripter
$tableScripter.Options.AppendToFile = $True
$tableScripter.Options.AllowSystemObjects = $False
$tableScripter.Options.ClusteredIndexes = $True
$tableScripter.Options.Indexes = $True
$tableScripter.Options.ScriptData = $True
$tableScripter.Options.ToFileOnly = $True
$tableScripter.Options.filename = $outfile
## build out the script for each table we defined earlier
foreach ($table in $tables)
{
$tableScripter.enumscript(#($db.tables[$table])) #enumscript expects an array. this is ugly, but it gives it what it wants.
}
I have a Visual Studio form running with VB.net and I'm collecting info needed to setup an AD user. In the end, this info will need to simply be passed to Powershell with no return info needed. Before that though, I need it to check if a printer code has already been assigned to someone before allowing it to be submitted to another user. I have a simple powershell script written up for it.
(We use the Pager field to store the printer code.)
Import-Module ActiveDirectory
$Page = $args[0]
Get-ADUser -Filter { Pager -like $Page } | FT Name
I setup the code I found HERE, and attempted to modify it to my script but it keeps crashing on
Dim results As Collection(Of PSObject) = MyPipeline.Invoke()
It gives me: An unhandled exception of type 'System.Management.Automation.ParseException' occurred in System.Management.Automation.dll
If I run his little 6+5 basic example script, it works, but when I try to retrieve info and return a name, it doesn't like it. How can I get it to return the name of the person if it find it? And since it won't run, I'm not even sure if passing the printer code as $args[0] is going to work yet.
Your results is expecting a collection of PowerShell objects. When you pipe the Get-ADUser command to Format-Table, it effectively strips the object down to a stream of strings. Try without the | FT Name.
Import-Module ActiveDirectory #if you're using powershell 3 or later, this may be redundant
# $Page = $args[0] # don't need to do this
$results = Get-ADUser -Filter { Pager -like $args[0] }
Write-Verbose $results
#Write-Verbose $results.Name #try this if the above one works
Update:
Write-Verbose may be causing an issue.
Try this:
Get-ADUser -Filter { Pager -like $args[0] }
Just that one line as the total PS code. (Assuming you have PowerShell 3.0 or later, you don't need Import-Module) That line will return objects of type TypeName: Microsoft.ActiveDirectory.Management.ADUser (from `Get-ADUser username | Get-Member).
You may also be able to use the .Net object type directly, without PowerShell. I'm not knowledgeable about .NET beyond what I picked up working with PowerShell.

Hello all and thanks for your time in advance;
I'm running into a slight issue.
I'm running a command and piping it into a variable so i can manipulate the output.
$variable = some command
this normally works fine but doesn't output what's happening to the screen, which is fine most of the time. However occasionally this command requires some user input (like yes or no or skip for example), and since it's not actually piping anything to the command window, it just sits there hanging instead of prompting the user. If you know what to expect you can hit y or n or s and it'll proceed normally.
Is there anyway to run the command so that the output is piped to a variable AND appears on screen? I've already tried:
($variable = some command)
I've also tried:
write-host ($variable = some command)
But neither work. Note that the command running isn't a native windows or shell command and I cannot just run it twice in a row.
To clarify (because i probably wasn't clear)
I've also tried :
$variable = some command : Out-host
and
$variable = some command | out-default
with all their parameters, But the "prompt" from the command (to write y, n, s) doesn't show up.
Being able to pass S automatically would also be acceptable.
Sounds like you need Tee-Object. Example:
some command | Tee-Object -Variable MyVariable
This should pass everything from the command down the pipe, as well as store all output from the command in the $MyVariable variable for you.
You need to give some specific example that doesn't work. I tried this and it works:
function test { $c = read-host "Say something"; $c }
$x = test
I still see "Say something". read-host does not output to standard output so your problem is surprising. Even this works:
read-host "Say something" *> out
=== EDIT ===
Since this is interaction with cmd.exe you have two options AFAIK. First, test command:
test.cmd
#echo off
set /p something="Say something: "
echo %something%
This doesn't work as you said: $x= ./test.cmd
To make it work:
a) Replace above command with: "Say something:"; $x= ./test.cmd. This is obviously not ideal in general scenario as you might not know in advance what the *.cmd will ask. But when you do know its very easy.
b) Try this:
Start-transcript test_out;
./test.cmd;
Stop-transcript;
gc .\test_out | sls 'test.cmd' -Context 0,1 | select -Last 1 | set y
rm test_out
$z = ($y -split "`n").Trim()
After this $z variable contains: Say something: something. This could be good general solution that you could convert to function:
$z = Get-CmdOutput test.cmd
Details of text parsing might be slightly different in general case - I assumed here that only 1 question is asked and answer is on the same line but in any case with some work you will be able to get everything cmd.exe script outputed in general case:
=== EDIT 2 ===
This might be a better general extraction:
$a = gi test_out; rm test_out
$z = $a | select -Index 14,($a.count-5)
$z
$variable = ""
some command | % {$variable += $_;"$_"}
This executes the command, and each line of output is both added to $variable and printed to the console.
