Error while running powershell script - Cannot bind argument to parameter 'Path' because it is null.
Posted on 2010-09-20
Hello,
I have one script for renaming homefolders and setting ACLs. It works on my personal laptop but not at work.
Gives me this error: "Cannot bind argument to parameter 'Path' because it is null.
At :line:5 char:11
+ (Get-Item <<<< $_.ColumnA).MoveTo($_.Colu
I know its probably some settings, but I cannot manage it.
I am running PowerGui script editor ver. 2.1.1.1202 .
Any idea?
Many thx
--------------------------
$DomainName = "xxx"
$LogosDomain = "yyyy"
Import-CSV C:\users.csv | %{
$Folder = Get-Item $_.ColumnA
$NewFullName = $Folder.FullName -Replace $Folder.Name, $_.ColumnB
$Folder.MoveTo($NewFullNam
$ACL = Get-ACL $NewFullName
$AccessRule2 = New-Object Security.AccessControl.Fil
"$LogosDomain\$($_.ColumnA
$AccessRule = New-Object `
System.Security.AccessCont
"$DomainName\$($_.ColumnB)
$ACL.RemoveAccessRuleAll($
$ACL.AddAccessRule($Access
Set-ACL $NewFullName -AclObject $ACL
}

It reads like a problem in your input file rather than the script.
I suggest you Write-Host the values it's trying to use before you use them.

Hello, csv file looks like this :
ColumnA;ColumnB
C:\A;C
C:\B;D
------------------------
IF I RUN:
Import-CSV C:\test.csv
I GET:
ColumnA;ColumnB
---------------
C:\A;C
C:\B;D
BUT IT FAILS ON(Get-Item):
Import-CSV C:\test.csv | %{
$Folder = Get-Item $_.ColumnA
$NewFullName = $Folder.FullName -Replace $Folder.Name, $_.ColumnB
$Folder.MoveTo($NewFullNam
write $NewFullName
}
Many Thanks
ColumnA;ColumnB
C:\A;C
C:\B;D

That's not a CSV file.
CSV is Comma Separated Values, your delimiter is a semi-colon.
You can either change that, or run Import-Csv like this:
Import-Csv C:\test.csv -Delimiter ";" | ....
Chris
Hi,
I dont know.
--------------------------
Import-CSV C:\test.csv -Delimiter ";" | %{
$Folder = Get-Item $_.ColumnA
$Folder
}
--------------------
Cannot bind argument to parameter 'Path' because it is an empty string.
At :line:7 char:20
+ $Folder = Get-Item <<<< $_.ColumnA
I dont know.
--------------------------
Import-CSV C:\test.csv -Delimiter ";" | %{
$Folder = Get-Item $_.ColumnA
$Folder
}
--------------------
Cannot bind argument to parameter 'Path' because it is an empty string.
At :line:7 char:20
+ $Folder = Get-Item <<<< $_.ColumnA
Run this bit on its own and check you get something useful back:
Import-CSV C:\test.csv -Delimiter ";"
It's entirely possible you have trailing blank lines as well.
Chris
Import-CSV C:\test.csv -Delimiter ";"
--------------------------
ColumnA ColumnB
------- -------
C:\A B
--------------------------
ColumnA ColumnB
------- -------
C:\A B
Try this:
Import-Csv "C:\test.csv" -Delimiter ";" | ForEach-Object {
Write-Host "Path: '$($_.ColumnA)'"
Get-Item $_.ColumnA
}
See how many times it tells you about Path.
Chris
Path: ''
Cannot bind argument to parameter 'Path' because it is an empty string.
At :line:3 char:10
+ Get-Item <<<< $_.ColumnA
Cannot bind argument to parameter 'Path' because it is an empty string.
At :line:3 char:10
+ Get-Item <<<< $_.ColumnA
But it makes me crazy, i have at home installed server 2003 in virtual pc, I installed there powergui etc..
And it works.
And it works.
You have an empty line in your file.
You could work around that in PowerShell, but it's a problem in the file, not PowerShell.
Chris
Import-Csv "C:\test.csv" -Delimiter ";" | Where-Object { $_.ColumnA } | ForEach-Object {
Write-Host "Path: '$($_.ColumnA)'"
Get-Item $_.ColumnA
}
So do y think is there possible solution to remake script or should I use:
ren C:\A B | icacls c:\B /remove xx\yy /grant xx\yy:(OI)(CI)(M)
many thanks
ren C:\A B | icacls c:\B /remove xx\yy /grant xx\yy:(OI)(CI)(M)
many thanks
by the way it gives me:
Path: 'C:\A'
Cannot find path 'C:\A' because it does not exist.
At :line:3 char:10
+ Get-Item <<<< $_.ColumnA
Path: 'C:\B'
Cannot find path 'C:\B' because it does not exist.
At :line:3 char:10
+ Get-Item <<<< $_.ColumnA
Path: 'C:\A'
Cannot find path 'C:\A' because it does not exist.
At :line:3 char:10
+ Get-Item <<<< $_.ColumnA
Path: 'C:\B'
Cannot find path 'C:\B' because it does not exist.
At :line:3 char:10
+ Get-Item <<<< $_.ColumnA
I don't see a need to remake the script, there's really not very much to it.
> ren C:\A B | icacls c:\B /remove xx\yy /grant xx\yy:(OI)(CI)(M)
You don't really want a pipeline there, you're not passing anything along. You can just use:
ren C:\A B
icacls c:\B /remove xx\yy /grant xx\yy:(OI)(CI)(M)
And the error message... well if that path doesn't exist... I can't help you with that :)
Chris
Thanks :-) , I am an idiot. Let me ask you another question before I accept it.
ren C:\A B | icacls c:\B /remove xx\yy /grant xx\yy:(OI)(CI)(M)
I know it doesn't send an object via pipe. I only wanted to pass it into one line, I have about 600 homefolders and wanted to create a *.bat and run it at the same time.
Thanks again
