I have a simple PowerShell script in which I try to write some log data.
The script that's not working:
Add-Content -Path C:\temp\logg.txt -Value $file.FullName
This line I placed in the middle of the script and I never get any text in the logg.txt. The Script executes fine except this, it compiles some files to a zip file.
This is on a Windows server.
If I, however, run the same script on my local machine, Win7, it does work!?
So I think it must be something with the server but I can't figure it out. Am using -ExecutionPolicy Bypass when I run the script.
EDIT: more info.
The script is called from an ASP.NET webpage:
Process.Start("Powershell.exe", "-ExecutionPolicy Bypass -Command ""& {" & destinationFolderRoot.Replace("\\", "\") & "\scriptParameters.ps1}""")
BaseZipScript:
function New-Zip
{
param([string]$zipfilename)
Set-Content $zipfilename ("PK" + [char]5 + [char]6 + ("$([char]0)" * 18))
(dir $zipfilename).IsReadOnly = $false
}
function Add-Zip
{
param([string]$zipfilename)
if(-not (Test-Path($zipfilename)))
{
Set-Content $zipfilename ("PK" + [char]5 + [char]6 + ("$([char]0)" * 18))
(dir $zipfilename).IsReadOnly = $false
}
$shellApplication = New-Object -COM Shell.Application
$zipPackage = $shellApplication.NameSpace($zipfilename)
foreach($file in $input)
{
$zipPackage.CopyHere($file.FullName)
Add-Content -Path "C:\temp\logg.txt" -Value $file.FullName
Start-Sleep -Milliseconds 750
}
}
scriptParameters1:
. "C:\temp\multiDownload\baseZipScript.ps1"
New-Zip c:\temp\multiDownload\user379\2016-09-15_14.39\files_2016-09-15_14.39.zip
dir c:\temp\multiDownload\user379\2016-09-15_14.39\tempCopy\*.* -Recurse |
Add-Zip c:\temp\multiDownload\user379\2016-09-15_14.39\files_2016-09-15_14.39.zip
Start-sleep -milliseconds 250
exit
As I said earlier the script works on local machine and also on the server, e.g. the files are being zipped, except that on the server nothing is logged in logg.txt.
Though the logg.txt works and exists on the server because the webpage also log some info there and that is being written.
Update:
As the comments guessed it was as simple as write access to the file. Though, it is kind of wierd because all files are created from the webservice if they doesn't exists? Any how, it works now. Thx! : )

I am assuming I missed something in my install? Anyone know what this error is or how to get passed it?
I upvoted this in the past, then apparently found the answer somewhere else, then forgot the answer again and ended up here again.
Adding <AutoParameterizationWebConfigConnectionStrings>False</AutoParameterizationWebConfigConnectionStrings>
in the csproj on the right PropertyGroup fixed the problem for me.
I'm trying to use powershell to write a script that calls net.exe's delete on a collection of computers meeting the specific case of having 3 or fewer files open. I'm fairly new at this, obviously, as I'm getting odd errors.
Using the example at Microsoft's blog I made the function below out of net session.
Function Get-ActiveNetSessions
{
# converts the output of the net session cmd into a PSobject
$output = net session | Select-String -Pattern \\
$output | foreach {
$parts = $_ -split "\s+", 4
New-Object -Type PSObject -Property #{
Computer = $parts[0].ToString();
Username = $parts[1];
Opens = $parts[2];
IdleTime = $parts[3];
}
}
}
which does produce a workable object that I can apply logic to.
I can use
$computerList = Get-ActiveNetSessions | Where-Object {$_.Opens -clt 3} | Select-Object {$_.Computer} to pull all computers with less than three opens into a variable, too.
What fails is the loop below
ForEach($computer in $computerList)
{
net session $computer /delete
}
with the error
net : The syntax of this command is:
At line:5 char:5
net session $computer /delete
CategoryInfo :NotSpecified (The syntax of this command is::String) [], RemoteException
FullyQualifiedErrorId : NativeCommandError
NET SESSION
[\\computername] [/DELETE] [/LIST]
Trying to run it with a call of $computer = $computer.ToString() ahead of the execution so it sees a string causes the script to hang without dropping the sessions, forcing me to close and reopen the ISE.
What should I do to get this loop working? Any help is appreciated.
Net session expects a \\ before the server name, it looks like. Have you given that a try?
here's what I am trying to do.
I have a few hundred users My Documents folders in which most(not all) have a file(key.shk for shortkeys program).
I need to upgrade the software but doing so makes changes to the original file.
I would like to run a batch file on the server to find the files in each My Docs folder and make a copy of it there called backup.shk
I can then use this for roll back.
The folder structure looks like this
userA\mydocs
userB\mydocs
userC\mydocs
My tools are xcopy, robocopy or powershell
Thanks in advance
This powershell script works... save as .ps1

How do I ask PowerShell where something is?
For instance, "which notepad" and it returns the directory where the notepad.exe is run from according to the current paths.
The very first alias I made once I started customizing my profile in PowerShell was 'which'.
New-Alias which get-command
To add this to your profile, type this:
"`nNew-Alias which get-command" | add-content $profile
The `n at the start of the last line is to ensure it will start as a new line.
Here is an actual *nix equivalent, i.e. it gives *nix-style output.
Get-Command <your command> | Select-Object -ExpandProperty Definition
Just replace with whatever you're looking for.
PS C:\> Get-Command notepad.exe | Select-Object -ExpandProperty Definition
C:\Windows\system32\notepad.exe
When you add it to your profile, you will want to use a function rather than an alias because you can't use aliases with pipes:
function which($name)
{
Get-Command $name | Select-Object -ExpandProperty Definition
}
Now, when you reload your profile you can do this:
PS C:\> which notepad
C:\Windows\system32\notepad.exe
I usually just type:
gcm notepad
or
gcm note*
gcm is the default alias for Get-Command.
On my system, gcm note* outputs:
[27] » gcm note*
CommandType Name Definition
----------- ---- ----------
Application notepad.exe C:\WINDOWS\notepad.exe
Application notepad.exe C:\WINDOWS\system32\notepad.exe
Application Notepad2.exe C:\Utils\Notepad2.exe
Application Notepad2.ini C:\Utils\Notepad2.ini
You get the directory and the command that matches what you're looking for.
Try this example:
(Get-Command notepad.exe).Path
My proposition for the Which function:
function which($cmd) { get-command $cmd | % { $_.Path } }
PS C:\> which devcon
C:\local\code\bin\devcon.exe
A quick-and-dirty match to Unix which is
New-Alias which where.exe
But it returns multiple lines if they exist so then it becomes
function which {where.exe command | select -first 1}
I like Get-Command | Format-List, or shorter, using aliases for the two and only for powershell.exe:
gcm powershell | fl
You can find aliases like this:
alias -definition Format-List
Tab completion works with gcm.
To have tab list all options at once:
set-psreadlineoption -editmode emacs
This seems to do what you want (I found it on http://huddledmasses.org/powershell-find-path/):
Function Find-Path($Path, [switch]$All = $false, [Microsoft.PowerShell.Commands.TestPathType]$type = "Any")
## You could comment out the function stuff and use it as a script instead, with this line:
#param($Path, [switch]$All = $false, [Microsoft.PowerShell.Commands.TestPathType]$type = "Any")
if($(Test-Path $Path -Type $type)) {
return $path
} else {
[string[]]$paths = #($pwd);
$paths += "$pwd;$env:path".split(";")
$paths = Join-Path $paths $(Split-Path $Path -leaf) | ? { Test-Path $_ -Type $type }
if($paths.Length -gt 0) {
if($All) {
return $paths;
} else {
return $paths[0]
}
}
}
throw "Couldn't find a matching path of type $type"
}
Set-Alias find Find-Path
Check this PowerShell Which.
The code provided there suggests this:
($Env:Path).Split(";") | Get-ChildItem -filter notepad.exe
Try the where command on Windows 2003 or later (or Windows 2000/XP if you've installed a Resource Kit).
BTW, this received more answers in other questions:
Is there an equivalent of 'which' on Windows?
PowerShell equivalent to Unix which command?
If you want a comamnd that both accepts input from pipeline or as paramater, you should try this:
function which($name) {
if ($name) { $input = $name }
Get-Command $input | Select-Object -ExpandProperty Path
}
copy-paste the command to your profile (notepad $profile).
Examples:
❯ echo clang.exe | which
C:\Program Files\LLVM\bin\clang.exe
❯ which clang.exe
C:\Program Files\LLVM\bin\clang.exe
I have this which advanced function in my PowerShell profile:
function which {
<#
.SYNOPSIS
Identifies the source of a PowerShell command.
.DESCRIPTION
Identifies the source of a PowerShell command. External commands (Applications) are identified by the path to the executable
(which must be in the system PATH); cmdlets and functions are identified as such and the name of the module they are defined in
provided; aliases are expanded and the source of the alias definition is returned.
.INPUTS
No inputs; you cannot pipe data to this function.
.OUTPUTS
.PARAMETER Name
The name of the command to be identified.
.EXAMPLE
PS C:\Users\Smith\Documents> which Get-Command
Get-Command: Cmdlet in module Microsoft.PowerShell.Core
(Identifies type and source of command)
.EXAMPLE
PS C:\Users\Smith\Documents> which notepad
C:\WINDOWS\SYSTEM32\notepad.exe
(Indicates the full path of the executable)
#>
param(
[String]$name
)
$cmd = Get-Command $name
$redirect = $null
switch ($cmd.CommandType) {
"Alias" { "{0}: Alias for ({1})" -f $cmd.Name, (. { which $cmd.Definition } ) }
"Application" { $cmd.Source }
"Cmdlet" { "{0}: {1} {2}" -f $cmd.Name, $cmd.CommandType, (. { if ($cmd.Source.Length) { "in module {0}" -f $cmd.Source} else { "from unspecified source" } } ) }
"Function" { "{0}: {1} {2}" -f $cmd.Name, $cmd.CommandType, (. { if ($cmd.Source.Length) { "in module {0}" -f $cmd.Source} else { "from unspecified source" } } ) }
"Workflow" { "{0}: {1} {2}" -f $cmd.Name, $cmd.CommandType, (. { if ($cmd.Source.Length) { "in module {0}" -f $cmd.Source} else { "from unspecified source" } } ) }
"ExternalScript" { $cmd.Source }
default { $cmd }
}
}
Use:
function Which([string] $cmd) {
$path = (($Env:Path).Split(";") | Select -uniq | Where { $_.Length } | Where { Test-Path $_ } | Get-ChildItem -filter $cmd).FullName
if ($path) { $path.ToString() }
}
# Check if Chocolatey is installed
if (Which('cinst.bat')) {
Write-Host "yes"
} else {
Write-Host "no"
}
Or this version, calling the original where command.
This version also works better, because it is not limited to bat files:
function which([string] $cmd) {
$where = iex $(Join-Path $env:SystemRoot "System32\where.exe $cmd 2>&1")
$first = $($where -split '[\r\n]')
if ($first.getType().BaseType.Name -eq 'Array') {
$first = $first[0]
}
if (Test-Path $first) {
$first
}
}
# Check if Curl is installed
if (which('curl')) {
echo 'yes'
} else {
echo 'no'
}
You can install the which command from https://goprogram.co.uk/software/commands, along with all of the other UNIX commands.
If you have scoop you can install a direct clone of which:
scoop install which
which notepad
There also always the option of using which. there are actually three ways to access which from Windows powershell, the first (not necessarily the best) wsl -e which command (this requires installation of windows subsystem for Linux and a running distro). B. gnuwin32 which is a port of several gnu binaries in .exe format as standle alone bundled lanunchers option three, install msys2 (cross compiler platform) if you go where it installed in /usr/bin you'll find many many gnu utils that are more up-to-date. most of them work as stand alone exe and can be copied from the bin folder to your home drive somewhere amd added to your PATH.
