I have a CSV like below:
location,id
loc1,1234
loc1,1235
loc1,1236
Running $a = Import-CSV C:\File.csv | Group-Object "location" I get the following output:
Count Name Group
----- ---- -----
3 loc1 {#{location=loc1; id=1234}, #{location=loc1; id=1235), #{location=loc1, id=1236}}
I would like to add all ID's to a single group (Using Add-QADGroupMember) but I can't figure out how to get a group of ID's for $loc1. It seems to be be grouping them correctly but I can't seem to parse the output into a single group. E.g $loc1 = 1234,1235,1236 that I can loop through.
Any suggestions would be appreciated!
Group-Object doesn't handle hashtables well, since the keys aren't real properties.
Assuming:
$csv = Import-CSV C:\File.csv
You should be able to do, for example:
$ids = $csv | %{ $_.id }
to get an array of the ID values. You'd probably want to pipe through Get-Unique for location.
If you wanted to get the location for a single ID quickly:
$location = $csv | ?{ $_.id -eq 42 } | %{ $_.location }
If you wanted to get an array of all IDs for a single location quickly (I think this is what you want):
$loc1 = $csv | ?{ $_.location -eq 'loc1' }
For reference, if you wanted to get a hashtable mapping each location to an array of IDs:
$groups = $csv | %{ $_.location } | &{
begin
{
$hash = #{}
}
process
{
$location = $_.location
$hash[$location] = $csv | ?{ $_.location -eq $location }
}
end
{
$hash
}
}
A bit tricky, but this will do it:
Import-Csv C:\File.csv | Group-Object "location" | %{Set-Variable ($_.Name) ($_.Group | Select-Object -ExpandProperty id)}
After running that, $loc1, $loc2, etc. will be arrays of all the ids for each location.
And yet another option:
(Import-Csv c:\foo.csv | Group Location -AsHashTable).Loc1 | Foreach {$_.id}
And if you're on V3, you can do this:
(Import-Csv c:\foo.csv | Group Location -AsHashTable).Loc1.Id

Two comma separated item added in array list and I would like to group them to count the total.
$list_distinct = [System.Collections.ArrayList]#()
$list_distinct.Add("Site A,Item A")
$list_distinct.Add("Site A,Item A")
$list_distinct.Add("Site A,Item B")
$list_distinct.Add("Site B,Item C")
$list_distinct.Add("Site B,Item D")
$list_distinct.Add("Site B,Item D")
Tried this:
$test = $list_distinct | Group-Object Values
The result shows Count (the whole total), Name(empty) and Group (the whole added items).
Any way to fix this? Or is there any better method?
Desired output example:
Site | Item | Count
Site A | Item A | 2
Site A | Item B | 1
Site B | Item C | 1
Site B | Item D | 2
Neither the ArrayList object nor its elements have a property Values. Non-existent properties are expanded to an empty result, so all of your values are grouped under the same (empty) name.
Change this
$list_distinct | Group-Object Values
into this
$list_distinct | Group-Object
and the problem will disappear.
For your desired output you will also need to split the values and create new (custom) objects:
$list_distinct | Group-Object | ForEach-Object {
$site, $item = $_.Name -split ','
New-Object -Type PSObject -Property #{
'Site' = $site
'Item' = $item
'Count' = $_.Count
}
} | Select-Object Site, Item, Count
The trailing Select-Object is to enforce field order since PowerShell hashtables aren't ordered by default.
In PowerShell v3 and newer you can simplify that to
$list_distinct | Group-Object | ForEach-Object {
$site, $item = $_.Name -split ','
[PSCustomObject]#{
'Site' = $site
'Item' = $item
'Count' = $_.Count
}
}
The trailing Select-Object isn't needed here, because the [PSCustomObject] type accelerator implicitly uses an ordered hashtable.
I have some simple Exchange Powershell I have written. I would like to list the UPN, Displayname, Item Count, and Item Size into a single CSV. However I have only been able to successfully push the data to two arrays and then manually combine them. Here is my code.
$MailBoxs = Get-Mailbox * | Select UserPrincipalName -ExpandProperty UserPrincipalName | Sort-Object UserPrincipalName
$Mailboxs2 = $MailBoxs.Where({ $_ -ne $null })
ForEach($MailBox2 in $MailBoxs2) { Get-MailboxStatistics $Mailbox2 | Sort-Object TotalItemSize –Descending | Select #{label=”User”;expression={$_.DisplayName}},#{label=”Total Size (MB)”;expression={$_.TotalItemSize.Value.ToMB()}},#{label=”Items”;expression={$_.ItemCount}} | Export-CSV "C:\T2\MailBoxSize.csv" -Append -NoTypeInformation }
ForEach($MailBox2 in $MailBoxs2) { $Mailbox2 | Export-CSV "C:\T2\MailBoxSize2.csv" -Append -NoTypeInformation }
Basically the second CSV gives me two fields for some reason the SMTP address and some random Length field, It also gives me a leading whitespace. If anyone has any ideas on how to clean this up I would love to hear them. Thanks for your time.
The multiple select statements were unnecessary. Here's a bit simplified way:
$mailboxes = #(Get-Mailbox *).
Where({$_.UserPrincipalName}) |
Sort-Object -Property UserPrincipalName
foreach ($box in $mailboxes) {
Get-MailboxStatistics $box.UserPrincipalName |
Sort-Object -Property TotalItemSize -Descending |
Select-Object -Property #(
#{L='UPN';E={$box.UserPrincipalName}}
#{L='User';E={$_.DisplayName}}
#{L='Total Size (MB)';E={$_.TotalItemSize.Value.ToMB()}}
#{L='Items';E={$_.ItemCount}}
) |
Export-Csv -Path 'C:\T2\MailBoxSize.csv' -NoTypeInformation -Append
}
Is it possible to display the results of a PowerShell Compare-Object in two columns showing the differences of reference vs difference objects?
For example using my current cmdline:
Compare-Object $Base $Test
Gives:
InputObject SideIndicator
987654 =>
555555 <=
123456 <=
In reality the list is rather long. For easier data reading is it possible to format the data like so:
Base Test
555555 987654
123456
So each column shows which elements exist in that object vs the other.
For bonus points it would be fantastic to have a count in the column header like so:
Base(2) Test(1)
555555 987654
123456
Possible? Sure. Feasible? Not so much. PowerShell wasn't really built for creating this kind of tabular output. What you can do is collect the differences in a hashtable as nested arrays by input file:
$ht = #{}
Compare-Object $Base $Test | ForEach-Object {
$value = $_.InputObject
switch ($_.SideIndicator) {
'=>' { $ht['Test'] += #($value) }
'<=' { $ht['Base'] += #($value) }
}
}
then transpose the hashtable:
$cnt = $ht.Values |
ForEach-Object { $_.Count } |
Sort-Object |
Select-Object -Last 1
$keys = $ht.Keys | Sort-Object
0..($cnt-1) | ForEach-Object {
$props = [ordered]#{}
foreach ($key in $keys) {
$props[$key] = $ht[$key][$_]
}
New-Object -Type PSObject -Property $props
} | Format-Table -AutoSize
To include the item count in the header name change $props[$key] to $props["$key($($ht[$key].Count))"].
I guess the question is in the title.
I have a CSV that looks something like
user,path,original_path
I'm trying to find duplicates on the original path, then output both the user and original_path line.
This is what I have so far.
$2 = Import-Csv 'Total 20_01_16.csv' | Group-Object -Property Original_path |
Where-Object { $_.count -ge 2 } | fl Group | out-string -width 500
This gives me the duplicates in Original_Path. I can see all the required information but I'll be danged if I know how to get to it or format it into something useful.
I did a bit of Googleing and found this script:
$ROWS = Import-CSV -Path 'Total 20_01_16.csv'
$NAMES = #{}
$OUTPUT = foreach ( $ROW in $ROWS ) {
IF ( $NAMES.ContainsKey( $ROW.Original_path ) -and $NAMES[$ROW.original_path] -lt 2 )
{ $ROW }
$NAMES[$ROW.original_path] += 1 }
Write-Output $OUTPUT
I'm reluctant to use this because, well first I have no idea what it's doing. So little of the makes any sense to me, I don't like using scripts I can't get my head around.
Also, and this is the more important part, it's only giving me a single duplicate, it's not giving me both sets. I'm after both offending lines, so I can find both users with the same file.
If anyone could be so kind as to lend a hand I'd appreciate it.
Thanks
It depends on the output format you need, but to build on what you already have we can use this to show the records in the console:
Import-Csv 'Total 20_01_16.csv' |
Group-Object -Property Original_path |
Where-Object { $_.count -ge 2 } |
Foreach-Object { $_.Group } |
Format-Table User, Path, Original_path -AutoSize
Alternatively, use this to save them in a new csv-file:
Import-Csv 'Total 20_01_16.csv' |
Group-Object -Property Original_path |
Where-Object { $_.count -ge 2 } |
Foreach-Object { $_.Group } |
Select User, Path, Original_path |
Export-csv -Path output.csv -NoTypeInformation
I am trying to iterate through emails, that have a specific subject line, and have the body of matching emails parsed and passed to a hash array. There is an issue with how I am trying to deal with multiple email bodies that is causing an issue.
$ol=New-Object -ComObject Outlook.Application
$ns=$ol.GetNameSpace('MAPI')
$inbox=$ns.GetDefaultFolder(6)
$Goodsubject='Interesting Email'
$mail = $InBox.items |
Where-Object{
$_.Unread -and $_.Subject -match $Goodsubject
#$_.Subject -match $Goodsubject
} |
Sort-Object ReceivedTime -Descending |
Select-Object Subject,ReceivedTime,Body,SenderName
# Select-Object Body
$mail | %{
$_.Body | %{$interestinghash = #{}} {
if ($_ -match "(.*): (.*)") {
$interestinghash[$matches[1]]=$matches[2];
}
}
Assuming the email has 4 line, each with a key: value, and I look at $interestinghash, I will only have the a key value pair for a email. I will not have all 4. That said, I can replace the following line:
$mail | %{
$_.Body | %{$interestinghash = #{}} {
if ($_ -match "(.*): (.*)") {
$interestinghash[$matches[1]]=$matches[2];
}
}
With:
$mail | %{$interestinghash = #{}} {
if ($_ -match "(.*): (.*)") {
$interestinghash[$matches[1]]=$matches[2];
}
}
If I do this it will give me all 4 values but will only look at 1 email. I am not sure what I am doing wrong here.
