I am having a text file that has content in this manner.
One;Thomas;Newyork;2020-12-31 14:00:00;0
Two;David;London;2021-01-31 12:00:00;0
Three;James;Chicago;2021-01-20 15:00:00;0
Four;Edward;India;2020-12-25 15:00:00;0
In these entries according to date time, two are past entries and two are future entries. The last 0 in the string indicates the Flag. With the past entries that flag needs to be changed to 1.
Consider all the entries are separated with the array. I tried this block of code but its not working to solve the problem here.
for ($item=0 ; $item -lt $entries.count ; $item++)
{
if ($entries.DateTime[$item] -lt (Get-Date -Format "yyyy-MM-dd HH:mm:ss"))
{
$cont = Get-Content $entries -ErrorAction Stop
$string = $entries.number[$item] + ";" + $entries.name[$item] + ";" +
$entries.city[$item]+ ";" + $entries.DateTime[$item]
$lineNum = $cont | Select-String $string
$line = $lineNum.LineNumber + 1
$cont[$line] = $string + ";1"
Set-Content -path $entries
}
}
I am getting errors with this concept.
Output should come as:-
One;Thomas;Newyork;2020-12-31 14:00:00;1 ((Past Deployment with respect to current date)
Two;David;London;2021-01-31 12:00:00;0

Four;Edward;India;2020-12-25 15:00:00;1 (Past Deployment with respect to current date)
This output needs to be overwritten on the file from where the content is extracted ie Entries.txt
param(
$exampleFileName = "d:\tmp\file.txt"
)

Background: I've been using Netwrix to audit permissions to network shares for a few years now and It's only ever worked smoothly 1 time..... So I've decided to move on to just an automated powershell script. I've run into a block. When I try to parse out the group members, it doesn't like the network name in front of the group name (TBANK). Then I also need to take the next step of just showing the name instead of the whole output of get-adgroupmember. Any help would be greatly appreciated as I'm very to to scripting with powershell. Current script below:
$OutFile = "C:\users\user1\Desktop\test.csv" # Insert folder path where you want to save your file and its name
$Header = "Folder Path,IdentityReference, Members,AccessControlType,IsInherited,InheritanceFlags,PropagationFlags"
$FileExist = Test-Path $OutFile
If ($FileExist -eq $True) {Del $OutFile}
Add-Content -Value $Header -Path $OutFile
$Folder = "\\server1.tbank.com\share1"
$ACLs = get-acl $Folder | ForEach-Object { $_.Access }
Foreach ($ACL in $ACLs){
$ID = $ACL.IdentityReference
$ID = $ID -replace 'TBANK\' , ''
$ACType = $ACL.AccessControlType
$ACInher = $ACL.IsInherited
$ACInherFlags = $ACL.InheritanceFlags
$ACProp = $ACL.PropagationFlags
$Members = get-adgroupmember $ID.
$OutInfo = $Folder + "," + $ID + "," + $Members + "," + $ACType + "," + $ACInher + "," + $ACInherFlags + "," + $ACProp
Add-Content -Value $OutInfo -Path $OutFile
}
First of all, there is a way better way to output a CSV file than by trying to write each row yourself (with the risk of missing out required quotes), called Export-Csv.
To use that cmdlet, you wil need to create an array of objects which is not hard to do.
$OutFile = "C:\users\user1\Desktop\test.csv" # Insert folder path where you want to save your file and its name
$Folder = "\\server1.tbank.com\share1"
# get the Acl.Access for the folder, loop through and collect PSObjects in variable $result
$result = (Get-Acl -Path $Folder).Access | ForEach-Object {
# -replace uses regex, so you need to anchor to the beginning of
# the string with '^' and escape the backslash by doubling it
$id = $_.IdentityReference -replace '^TBANK\\' # remove the starting string "TBANK\"
# Get-ADGroupMember can return users, groups, and computers. If you only want users, do this:
# $members = (Get-ADGroupMember -Identity $id | Where-Object { $_.objectClass -eq 'user'}).name -join ', '
$members = (Get-ADGroupMember -Identity $id).name -join ', '
# output an onbject with all properties you need
[PsCustomObject]#{
'Folder Path' = $Folder
'IdentityReference' = $id
'Members' = $members
'AccessControlType' = $_.AccessControlType
'IsInherited' = $_.IsInherited
'InheritanceFlags' = $_.InheritanceFlags -join ', '
'PropagationFlags' = $_.PropagationFlags -join ', '
}
}
# output on screen
$result | Format-List
# output to CSV file
$result | Export-Csv -Path $OutFile -Force -UseCulture -NoTypeInformation
I've added a lot of inline comments to hopefully make things clear for you.
The -UseCulture switch in the Export-Csv line makes sure the field delimiter that is used matches what is set in your system as list separator. This helps when opening the csv file in Excel.
P.S> the Get-ADGroupMember cmdlet also has a switch called -Recursive. With that, it will also get the members from groups inside groups
I have a directory of .txt files that look like this:
[LINETYPE]S[STARTTIME]00:00:00
[LINETYPE]P[STARTTIME]00:00:00
[LINETYPE]B[STARTTIME]00:59:00
[LINETYPE]C[STARTTIME]00:59:00
[LINETYPE]C[STARTTIME]00:59:30
[LINETYPE]S[STARTTIME]01:00:00
[LINETYPE]P[STARTTIME]01:00:00
[LINETYPE]B[STARTTIME]01:59:00
[LINETYPE]C[STARTTIME]01:59:00
[LINETYPE]C[STARTTIME]01:59:30
[LINETYPE]S[STARTTIME]02:00:00
I'd like to remove all occurrences of [LINETYPE]S except the first, which happens to always be 00:00:00 and on the first line, and then re-save the file to a new location.
That is, [LINETYPE]S[STARTTIME]00:00:00 must always be present, but the other lines that start with [LINETYPE]S need to be removed.
This is what I came up with, which works except it removes all [LINETYPE]S lines, including the first. I can't seem to figure out how to do that part after Googling for a while, so I'm hoping someone can point me in the right direction. Thanks for your help!
Get-ChildItem "C:\Users\Me\Desktop\Samples" -Filter *.txt | ForEach-Object {
Get-Content $_.FullName | Where-Object {
$_ -notmatch "\[LINETYPE\]S"
} | Set-Content ('C:\Users\Me\Desktop\Samples\Final\' + $_.BaseName + '.txt')
}
i couldn't figure out how to do this via a pipeline [blush], so i went with a foreach loop and a compound test.
# fake reading in a text file
# in real life, use Get-Content
$InStuff = #'
[LINETYPE]S[STARTTIME]00:00:00
[LINETYPE]P[STARTTIME]00:00:00
[LINETYPE]B[STARTTIME]00:59:00
[LINETYPE]C[STARTTIME]00:59:00
[LINETYPE]C[STARTTIME]00:59:30
[LINETYPE]S[STARTTIME]01:00:00
[LINETYPE]P[STARTTIME]01:00:00
[LINETYPE]B[STARTTIME]01:59:00

[LINETYPE]C[STARTTIME]01:59:30

'# -split [System.Environment]::NewLine
$KeepFirst = '[LINETYPE]S'
$FoundFirst = $False
$FilteredList = foreach ($IS_Item in $InStuff)
{
if ($IS_Item.StartsWith($KeepFirst))
{
if (-not $FoundFirst)
{
$IS_Item
$FoundFirst = $True
}
}
else
{
$IS_Item
}
}
$FilteredList
output ...
[LINETYPE]S[STARTTIME]00:00:00
[LINETYPE]P[STARTTIME]00:00:00
[LINETYPE]B[STARTTIME]00:59:00
[LINETYPE]C[STARTTIME]00:59:00
[LINETYPE]C[STARTTIME]00:59:30
[LINETYPE]P[STARTTIME]01:00:00
[LINETYPE]B[STARTTIME]01:59:00
[LINETYPE]C[STARTTIME]01:59:00
[LINETYPE]C[STARTTIME]01:59:30
at that point, you can send the new collection out to a file. [grin]
Try the following:
Get-ChildItem "C:\Users\Me\Desktop\Samples" -Filter *.txt |
Foreach-Object {
$count = 0
Get-Content $_.FullName |
Where-Object { $_ -notmatch '\[LINETYPE\]S' -or $count++ -eq 0 } |
Set-Content ('C:\Users\Me\Desktop\Samples\Final\' + $_.BaseName + '.txt')
}
The script block passed to Where-Object runs in the same scope as the caller, so variable $count can be directly updated.
The 1st line that does contain [LINETYPE]S is included, because $count is 0 at that point, after which $count is incremented ($count++); subsequent [LINETYPE]S are not included, because $count is then already greater than 0.
i have a txt file with this :
1230;
012;
45;
125
and i want to convert this in an int
but is doesn't work... he juste return the last number
here is my code :
$numbertxt = get-content -Path C:\mysticpath\number.txt -Raw
$numbertxt.GetType()
write-host $numbertxt
foreach ($flags in $numbertxt)
{
$integer = [int]$flags
}
echo $integer
somebody can help me ?
Sorry for my english
$numbertxt = (get-content -Path C:\mysticpath\number.txt -Raw) -split ';'
$numbertxt.GetType()
write-host $numbertxt
foreach ($flags in $numbertxt)
{
$integer = [int]$flags
echo $integer
}
First a integer can only be made of numbers so you will need to split the contents by ';'. This will make a array of strings that are numbers.
Also put the echo on the inside of the for loop will allow for it to display each number as its processed
try this method (control if it's convertible to integer before print)
$res=0;
#verbose version
(Get-Content "c:\temp\test.txt") -split ';' | where {[int]::TryParse($_, [ref] $res)} | foreach {$res}
#short version
(gc "c:\temp\test.txt") -split ';' | ?{[int]::TryParse($_, [ref] $res)} | %{$res}
Very very much a PowerShell newbie here I wanted a script to scan devices on the network and report on Local Admins. Found one out there and made some minor modifications to meet my needs - but I have one mod I cant work out how to do. Hoping someone out there will know a simple way to do it ?
The scrip below will read in a list of device names - scan them and output a dated report for all devices that are live and on-line. If the device is not accessible I get the following error on screen but nothing in the report.
I would like when it encounters an error that it writes to the report file - something along the lines of "$computor was not accessible!"
The code I am using is
$date = Get-Date -Format o | foreach {$_ -replace ":", "."}
ECHO "Starting scan"
$Result = #()
foreach($server in (gc .\servers.txt)){
$computer = [ADSI](”WinNT://” + $server + “,computer”)
$Group = $computer.psbase.children.find(”Administrators”)
$Filename = "c:\" + "LocalAdminAudit" + $date + ".txt"
function getAdmins
{
ECHO "SEARCHING FOR DEVICE"
$members = ($Group.psbase.invoke(”Members”) | %
{$_.GetType().InvokeMember(”Adspath”, ‘GetProperty’, $null, $_, $null)}) -
replace ('WinNT://DOMAIN/' + $server + '/'), '' -replace ('WinNT://DOMAIN/',
'DOMAIN\') -replace ('WinNT://', '')
$members}
ECHO "READY TO WRITE OUTPUT"
$Result += Write-Output "SERVER: $server"
$Result += Write-Output ' '
$Result += ( getAdmins )
$Result += Write-Output '____________________________'
$Result += Write-Output ' '
ECHO "Record written"
}
# Added date run to report
$result += Write-Output "Date Reported: $date"
$Result > $Filename
Invoke-Item $Filename
# replace "DOMAIN" with the domain name.
ECHO "Scan Complete"
And the on screen error when a machine is off line or otherwise doesn't respond is
Exception calling "Find" with "1" argument(s): "The network path was not found.
"
At \server\users\User.Name\Powershell Scripts\Get-Local-AdminsV3.ps1:1
0 char:40
+ $Group = $computer.psbase.children.find <<<< (”Administrators”)
+ CategoryInfo : NotSpecified: (:) [], MethodInvocationException
+ FullyQualifiedErrorId : DotNetMethodException
I would like when it encounters an error that it writes to the report file - something along the lines of "$computor was not accessible!" - I am pretty sure there must be an easy way of doing this - but I cant work it out so any tips would be greatly appreciated
As Matt, mentioned in the comments. You can use a Try/Catch block inside your function to catch the error.
I also made some other changes. The most major is that I changed the function to contain all of the code necessary to get the local administrator group. Then the loop just calls the function once per computer with the computer name. This function is then reusable.
Secondly rather than output to a text file, I changed to outputting to a CSV as is a more structured format that can be used better later.
Also rather than relying on writing to the console host, I used Write-Progress to report the progress of the loop.
$Servers = Get-Content .\servers.txt
$ExportFileName = "c:\LocalAdminAudit$date.csv"
function Get-LocalAdministrator {
[cmdletbinding()]
Param(
$ComputerName
)
$Group = [ADSI]("WinNT://$computername/Administrators,group")
try {
$Group.Invoke("Members") | ForEach-Object {
$User = ($_.GetType().InvokeMember("Adspath", 'GetProperty', $null, $_, $null) -split '/')[-2,-1] -join '\'
[PSCustomObject]#{
"User" = $User
"Server" = $ComputerName
"Date" = Get-Date -Format o | ForEach-Object {$_ -replace ":", "."}
}
}
}
catch {
[PSCustomObject]#{
"User" = "Failed to Report"
"Server" = $ComputerName
"Date" = Get-Date -Format o | ForEach-Object {$_ -replace ":", "."}
}
}
}
$LocalAdmins = foreach ($Server in $Servers) {
Write-Progress -Activity "Retrieving Local Administrators" -Status "Checking $Server" -PercentComplete (([array]::indexof($Servers,$Server)/($Server.count))*100)
Get-LocalAdministrator $Server
}
$LocalAdmins | Export-CSV $ExportFileName -NoTypeInformation
Invoke-Item $ExportFileName
Lastly, be careful of smart quotes especially when cutting and pasting between Outlook and word.

I'm stuck. I have a PowerShell script which looks to a specific folder for files which are older than 30 days from the last modified date (additionally, it'll create the folder if it doesn't exist). It creates the folder, it gives me the total files, it'll list all of the files in a test query, but it won't actually count the number of 30+ day old files. I've tried several methods to get this count (some deriving from other solutions to delete old files from this site), but PowerShell just doesn't want to do it.
Here's my code so far...
$HomePath = $env:USERPROFILE
$CompanyFolder = "\Company"
$TimeSensativeFolder = "\TimeSensative"
$TimeSensativePath = $HomePath+$CompanyFolder+$TimeSensativeFolder
$OldFilesAmount = 0
$TotalFilesAmount = 0
$TimeLimit = (Get-Date).AddDays(-30)
$StatusOK = "No old files were found in the time sensative folder."
$StatusCreated = "The time sensative folder was created."
$StatusError1 = "There were old files found in the time sensative folder!"
$StatusError2 = "Unable to create the time sensative folder!"
function MakeTimeSensativeFolder ($TimeSensativePath) {
try {
md $TimeSensativePath -Force -ErrorAction Stop
Write-Host $StatusCreated
}
catch {
Write-Host $StatusError2
}
}
function CountOldFiles () {
$OldFilesAmount = $OldFilesAmount + 1
}
if(!(Test-Path $TimeSensativePath -PathType Container)) {
MakePHIFolder $TimeSensativePath
}
else {
}
try {
$TotalFilesAmount = (Get-ChildItem $PHIPath -Recurse -File | Measure-Object).Count
# I've tried this...
Get-Item $PHIPath | Foreach {$_.LastWriteTime} -ErrorAction Stop
if (Get-Content $_.LastWriteTime | Where-Object {$_ -gt $TimeLimit}) {
CountOldFiles
}
# And I've tried this...
Get-ChildItem -Path $PHIPath -Recurse -File | Foreach-Object {
if (Get-Content $_.LastWriteTime | Where-Object {$_ -gt $TimeLimit}) {
CountOldFiles
}
}
# I've even tried this...
Get-ChildItem $PHIPath -Recurse -File | ? {
-not $_.PSIsContainer -and $_.LastWriteTime -lt $TimeLimit
} | CountOldFiles
# And this, as well...
Get-ChildItem -Path $PHIPath -Recurse -File | Where-Object {$_.LastWriteTime -gt $TimeLimit} | CountOldFiles
}
catch {
MakeTimeSensativeFolder $TimeSensativePath
}
# Used for testing.
<#
Get-ChildItem $TimeSensativePath -Recurse -File
Write-Host "TimeSensative folder exists:" $TimeSensativePathExists
Write-Host "Home TimeSensative path:" $TimeSensativePath
Write-Host "Old files found:" $OldFilesAmount
Write-Host "Total files found:" $TotalFilesAmount
Exit
#>
# Determining proper grammar for status message based on old file count.
if ($OldFilesAmount -eq 1) {
$StatusError1 = "There was "+$OldFilesAmount+" old file of "+$TotalFilesAmount+" total found in the PHI folder!"
}
if ($OldFilesAmount -gt 1) {
$StatusError1 = "There were "+$OldFilesAmount+" old files of "+$TotalFilesAmount+" total found in the PHI folder!"
}
# Give statuses.
if ($OldFilesAmount -gt 0) {
Write-Host $StatusError1
}
else {
Write-Host $StatusOK
}
Depending on which I tried, I would get no result or I'd get something like this:
Get-Content : Cannot find drive. A drive with the name '12/22/2016 17' does not exist.
At C:\Users\nobody\Scripts\PS1\ts_file_age.ps1:54 char:14

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : ObjectNotFound: (12/22/2016 17:String) [Get-Content], DriveNotFoundException
+ FullyQualifiedErrorId : DriveNotFound,Microsoft.PowerShell.Commands.GetContentCommand
In any instance, there's no old file count as I'm endeavoring to demand.
It's been a bit of a head scratcher. Any advice?
Thanks so much in advance!
Filtering files with last write time is easy enough. Like so,
$allFiles = gci
$d = (Get-Date).adddays(-30)
$newFiles = #()
$oldFiles = #()
$allFiles | % { if ($_.lastwritetime -ge $d) { $newFiles +=$_ } else { $oldFiles += $_ } }
What's done here is that first all the files are set in a collection. This isn't mandatory, but one can browse the collection to check that it's been populated properly. This is useful in cases one has complex paths or exclusion filters.
The second step is just to get a DateTime that is used later to divide files into old and new ones. Just like the sample did, so nothing interesting here. Actually, there's one little thing. The date is -30 days, but hours, minutes and seconds are based on current time. So if there's really tight limit, consider using midnight time ([datetime]::Today).AddDays(-30)
The third step is to declare two empty collections for new and old files.
The last step is to iterate through the $allFiles and check the last write time. If it's greater or equal to the cutpoint, add it into $newFiles, othervise $OldFiles.
After the last step, further processing should be simple enough.
This is what I do to get (delete in this case) files older than X days:
$Days = 5
$limit = (Get-Date).AddDays(-$Days)
$CurrentDate = Get-Date
#This will delete all files older than 5 days
Get-ChildItem -Path $Workdir -Recurse -Force | Where-Object { !$_.PSIsContainer -and $_.LastWriteTime -lt $limit } | Remove-Item -Force
