Powershell Update Active Directory Users Based on Delimited File - csv

If I have two rows in a CSV file like below (but 200 entries or so).
$Username $Phone
Example.A 911
Example.B 123
How would I get PowerShell to take each row and enter it into a command?
I know how to do it if the phonenumber (Using a for each loop) is the same for everyone, but if everyone has a different phonenumber, how would I go about it then? Can I use a for each loop fetching two rows instead of 1 row from the csv file?
Foreach $Username, $Phonenumber in $CSV
Set-ADuser -identity $Username -PhoneNumber $Phonenumber
Above is how I would like it to be, but that doesn't work.


To do what you're attempting, you just need a couple of slight modifications as follows:
$CSV = Import-Csv -Delimiter "," -Path "\\your\file\path"
foreach ($user in $CSV) {
Set-ADuser -identity $user.Username -PhoneNumber $user.Phonenumber
}

Powershell add header to blank csv

I have a process that I am trying to fully automated and have hit upon a stumbling block.
The process runs through a number of SQL queries and then outputs these results to different named CSV files.
Where my issue lies is that where no results are returned in the query to the dataset when I export the data (which I must do to satisfy auditors) there is no header data written to the CSV file.
What I need to do therefore is IF the dataset contains 0 rows then to simply export a CSV file containing the headings "Client", "Balance", "Account".
Where as if there is data within the table then the process can continue as it currently does.
What I am is unsure how the hell this can be achieved...
I am currently muting whether or not I will have to export the data and then write a loop to delete any lines from the CSV containing for example "Client" then re-import the CSV's add the column heading that I want and export it again. As this is messy, ideally I would like to keep away from this..
Code is
$SqlCmd.CommandTimeout=$timeout;
$SqlCMD.CommandText = $034CASHQUERY;
$SqlCmd.Connection = $SqlConnection;
## - Extract Data and build sql data object
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter;
$SqlAdapter.SelectCommand = $SqlCmd;
$DataSet = New-Object System.Data.DataSet;
$SqlAdapter.Fill($DataSet);
$DataSetTable = $DataSet.Tables["Table"];
IF($DataSet.Tables["Table"]){
$isnotnull
$DataSet.Tables["Table"] | Export-Csv $034CASHOUT -NoTypeInformation
echo "CL2 Exported"
}
else {
}
Has anyone come across this before or aware of how to iterate through the issue?

You could create a .csv file and add the header text manually.
$headerText = ('"Client","Balance","Account"' + "`n")
New-Item $034CASHOUT | Add-Content -value $headerText
Also, I think your IF condition may be a bit wonky. Are you looking for:
IF($DataSet.Tables["Table"] -isnot $null)
All together:
IF($DataSet.Tables["Table"] -isnot $null){
$DataSet.Tables["Table"] | Export-Csv $034CASHOUT -NoTypeInformation
echo "CL2 Exported"
}
else {
$headerText = ('"Client","Balance","Account"' + "`n")
New-Item $034CASHOUT | Add-Content -value $headerText
}
This is probably not the best way to do it, but I think this is what you described.

Can you please provide more information on the data you're processing? I understand if there is no data you want "Client", "Balance", "Account".
When there is data present, will it also be in these 3 columns?
If so this is your answer:
$DataSet.Tables["Table"] |
Select-Object Client,Balance,Account |
Export-Csv $034CASHOUT -NoTypeInformation

Merge two CSV files into one

I have two CSV files that don't have any unique identifiers. The number of rows of both files is always the same. I want to merge them as it is (the 2nd CSV as additional columns into the 1st CSV).
Content of file1.csv:
Server,Info
server1,item1
server1,item2
server1,item3
server2,item1
server2,item2
server2,item3
server3,item1
server3,item2
server3,item3
Content of file2.csv:
Items,ColumnA,ColumnB,ColumnC
item#1:,aa,jj,ss
item#2:,bb,kk,tt
item#3:,cc,ll,uu
item#1:,dd,mm,vv
item#2:,ee,nn,ww
item#3:,ff,oo,xx
item#1:,gg,pp,yy
item#2:,hh,qq,zz
item#3:,ii,rr,ab
Expecting output of csv file:
Server,Info,Items,ColumnA,ColumnB,ColumnC
server1,item1,item#1:,aa,jj,ss
server1,item2,item#2:,bb,kk,tt
server1,item3,item#3:,cc,ll,uu
server2,item1,item#1:,dd,mm,vv
server2,item2,item#2:,ee,nn,ww
server2,item3,item#3:,ff,oo,xx
server3,item1,item#1:,gg,pp,yy
server3,item2,item#2:,hh,qq,zz
server3,item3,item#3:,ii,rr,ab
I have search intensively in the net, but couldn't find any solution... Would really appreciate if someone can provide me some answers here...

You can use the Get-Content cmdlet to read both CSV files, iterate over it using a for-loop and use a format string to join them together. Finally, write the new file back using the Out-File cmdlet:
$file1 = Get-Content 'Path_to_file1.csv'
$file2 = Get-Content 'Path_to_file2.csv'
$content = for ($i = 0; $i -lt $file1.Length; $i++)
{
'{0},{1}' -f $file1[$i].Trim(), $file2[$i].Trim()
}
$content | out-file 'Path_to_file3.csv'

Find and Replace many Items with Powershell from Data within a CSV, XLS or two txt documents

So I recently have found the need to do a find and replace of mutliple items within a XML document. Currently I have found the code below which will allow me to do multiple find and replaces but these are hard coded within the powershell.
(get-content c:\temp\report2.xml) | foreach-object {$_ -replace "192.168.1.1", "Server1"} | foreach-object {$_ -replace "192.168.1.20", "RandomServername"} | set-content c:\temp\report3.xml
Ideally instead of hard coding the value I would like to find and replace from a list, ideally in a CSV or and XLSX. Maybe two txt file would be easier.
If it was from a CSV it could grab the value to find from A1 and the value to replace it with from B1 and keep looping down until the values are empty.
I understand I would have to use the get-content and the for each command I was just wondering if this was possible and how to go about it/ if anybody could help me.
Thanks in advance.

#next line is to clear output file
$null > c:\temp\report3.xml
$replacers = Import-Csv c:\temp\replaceSource.csv
gc c:\temp\aip.xml | ForEach-Object {
$output = $_
foreach ($r in $replacers) {
$output = $output -replace $r.ReplaceWhat, $r.ReplaceTo
}
#the output has to be appended, not to rewrite everything
return $output | Out-File c:\temp\report3.xml -Append
}
Content of replaceSource.csv looks like:
ReplaceWhat,ReplaceTo
192.168.1.1,server1
192.168.1.20,SERVER2
Note the headers

adding data or modifying data in powershell

I have a CSV file with users and dates in it.
I want to run a powershell script that will modify or add to that list.
I have the modify part down, but I can't get the script right to add a line.
Here is what I have.
The file is users.csv with the following data:
Username Date
Johnson 3/10/16
Smith 12/31/15
Brown 3/9/16
When the script runs, I want to check the username. if there is a match, update the date. if there isn't a match add a new line.
Here is my code:
Get time parts
$date=Get-Date -format d
Get username
$user=$env:username
import data and modify
($CSV= import-csv c:\users.csv -delimiter ',') | foreach {
if ($_.username -match $user) {
$_.date=$date
}
}
output
Export-csv c:\users.csv -notypeinformation -force
This will change the date for a user and export the file just fine.
I can't get the code write to read all the usernames and if there isn't a match to add a line at the end with a username and date.
I'm fairly new to powershell.
Thanks for your help
Charles

try this:
$date = Get-Date -format d
$user = $env:username
$csv = ipcsv c:\users.csv
$csv | % {if ($_.username -match $user) {$_.date = $date}}
if ($user -notin $csv.username) {$csv += [pscustomobject]#{Username = $user; Date = $date}}
$csv

PowerShell Error: Import-CSV Cannot Open File

My PowerShell code is tripping some strange error codes, which I have thoroughly searched for to no avail.
I am trying to create a script that calculates some basic statistics for a number of CSV files, which seems to work until I try to create and populate new columns.
The error code I'm getting is:
Import-Csv: Cannot open file "C:\zMFM\Microsoft.Powershell.Commands.GenericMeasureInfo".
At C:\zMFM\StatsDebug.ps1:46 Char:21
+$STATS2 = Import-CSV <<< $STATS
+CategoryInfo : OpenError (:) [Import-Csv], FileNotFoundException
+FullyQualifiedErrorId : FileOpenFailure.Microsoft.Powershell.Commands.ImportCsvCommand at C:\zMFM\statsdebug.ps1:55 char:20
That's followed by an error using a null expression, but I assume fixing this problem with Import-Csv will in turn fix that error. Here's my code, any help would be great, thanks!
$i = 1

}

$STDEVInputFile = Import-CSV $filename
...
$STATS = Import-CSV $Filename |
Measure-Object td -ave -max -min
# $STATS here will be type [GenericMeasureInfo], so you cannot use this as a filename.
$STATS2 = Import-CSV $Stats
# Are you trying to import $filename a third time here? You can't use $Stats because it's a [GenericMeasureInfo] object, not a [string].
Based on your code, it looks like you're trying to import a CSV with a filename of type [Microsoft.PowerShell.Commands.GenericMeasureInfo]. Filenames are strings. Also, why are you importing $filename twice? Would recommend importing it once, then operating off of the variable you saved it to.
Would also recommend changing your while loop to 1..211 | ForEach-Object. That way you won't have to worry about whether $i is less than or equal to your static number. Not a huge deal, but would make the code a little more readable.
TL;DR
Import-CSV $Stats is the problem. $Stats is not a valid filename, so you can't open/import it.
