I have a problem in PHP / Laravel to create multiple zip files synchronously, I copy all commands that is generated and squeeze into the Shell, it executes normally, but when I step into the PHP run it only generates the first file = /.
Controller code.
foreach ($passwords as $p){
if($i == 0){
$command = 'zip -u -j -P '.$p.' '.$dir.'/'.$count.'.zip '.storage_path().'/app/'.$directory.'/'.$file1->getClientOriginalName();
$commands->push($command);
}else{
$command = 'zip --quiet -j -P '.$p.' '.$dir.'/'.$count.'.zip '.storage_path().'/app/'.$directory.'/'.($count+1).'.zip';
$commands->push($command);
}
$count--;
$i++;
}
foreach ($commands as $p){
echo $p.'<br/>';
}
foreach ($commands as $c){
$process = new Process($c);
$process->start();
sleep(10);
if($process->isTerminated()){
sleep(1);
}
if ($errorOutput = $process->getErrorOutput()) {
throw new RuntimeException('Process: ' . $errorOutput);
}
}
Data $commands
The script only generates the file 50.zip.
Not sure if sleep could interfere with subprocess (shell command). Please try:
foreach ($commands as $c){
$process = new Process($c);
// Set the timeout instead of sleeping
$process->setTimeout(10);
$process->start();
// Wait for the process to finish
$process->wait();
if ($errorOutput = $process->getErrorOutput()) {
throw new RuntimeException('Process: ' . $errorOutput);
}
}
wait() call uses usleep in a more fine-grained manner it might help with that.
Does it work like this?
I am trying to run a powershell script and have it output to my asp.net site. I have made it work with a very simple script where the only command in the script was
Get-Service | Out-String
and this output onto my site everything I expected
but when I use the script I actually want info from it doesn't output anything
I can tell it runs (or trys to run) because when my site hits the code that invokes the script it hangs about 10 seconds.
The script I am trying to run is
$user = "user"
$token = "token"
$base64AuthInfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $user,$token)))
$result = Invoke-WebRequest -Method Get -Uri 'https://site.vsrm.visualstudio.com/defaultcollection/product/_apis/release/releases?definitionId=1&api-version=3.0-preview.2&$expand=environments' -ContentType "application/json" -Headers #{Authorization=("Basic {0}" -f $base64AuthInfo)}
$releaseArr = $result.Content | ConvertFrom-Json
[System.Collections.ArrayList]$enviromentName = #()
[System.Collections.ArrayList]$latestRelease = #()
foreach($env in $releaseArr.value[0].environments)
{
$enviromentName.Add($env.name) | Out-Null
}
foreach($releaseValue in $releaseArr.value)
{
For($i = 0; $i -lt $enviromentName.Count; $i++)
{
if($latestRelease[$i] -eq $null)
{
foreach($release in $releaseValue.environments)
{
if($release.name -eq $enviromentName[$i] -and $release.status -eq "succeeded")
{
$latestRelease.Add($releaseValue.name) | Out-Null
}
}
}
}
}
For($i = 0; $i -lt $enviromentName.Count; $i++)
{
Write-Host $enviromentName[$i] " : " $latestRelease[$i]
}
I know this script runs and outputs, but is there some code in this script that would cause it to not output properly.
The code in my asp.net site I am using to call the script is
ResultBox.Text = string.Empty;
// Initialize PowerShell engine
var shell = PowerShell.Create();
// Add the script to the PowerShell object
shell.Commands.AddScript(#"C:\Users\user\Desktop\script.ps1");
// Execute the script
var results = shell.Invoke();
// display results, with BaseObject converted to string
// Note : use |out-string for console-like output
if (results.Count > 0)
{
// We use a string builder ton create our result text
var builder = new StringBuilder();
foreach (var psObject in results)
{
// Convert the Base Object to a string and append it to the string builder.
// Add \r\n for line breaks
builder.Append(psObject.BaseObject.ToString() + "\r\n");
}
// Encode the string in HTML (prevent security issue with 'dangerous' caracters like < >
ResultBox.Text = Server.HtmlEncode(builder.ToString());
}
Change "Write-Host" to "Write-Output." Write-Host only outputs to interactive consoles.
You can see this in action:
Make a new PowerShell file and add a write-host statement to it:
[nick#nick-lt temp]$ New-Item -Type File -Path .\example.ps1 -Force
[nick#nick-lt temp]$ Set-Content .\example.ps1 "Write-Host 'Hello World'"
Then try and set a variable to the result of the script:
[nick#nick-lt temp]$ $what = .\example.ps1
Hello World
[nick#nick-lt temp]$ $what
[nick#nick-lt temp]$
Hello World shows up when the script executes but the variable is empty.
Now change it to write-output:
[nick#nick-lt temp]$ Set-Content .\example.ps1 "Write-Output 'Hello World'"
[nick#nick-lt temp]$ $what = .\example.ps1
[nick#nick-lt temp]$ $what
Hello World
The variable actually contains what it is supposed to now.
One of the cardinal rules of PowerShell is to not use Write-Host except in script that will be run interactively. .NET needs the results in the output stream not the host stream.
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?
In an effort to setup a "cron job" like scheduled task on Windows I've setup a Powershell script using code recommended via previous stackoverflow question.
I have some backups that I need to cleanup daily and delete old backups so I created a asp.net script to perform this task - the file name is BackupCleanup.aspx and I have confirmed that the ASP.net script does work when executed on its own by visiting the above url - I however cannot get it to execute using the Powershell script below.
The Powershell Script code I'm using is:
$request = [System.Net.WebRequest]::Create("http://127.0.0.1/BackupCleanup.aspx")
$response = $request.GetResponse()
$response.Close()
I have created this file with a PS1 extension, it shows properly in my os (Windows 2008) - I have tried both manually executing this task by right clicking and choosing "Run with Powershell" and also have scheduled this as a task - both to no avail.
I cannot figure out why the script does not work - any help would be GREATLY appreciated.
Here is the Powershell script I use to call up web pages using IE. Hopefully this will work for you as well.
Function NavigateTo([string] $url, [int] $delayTime = 100)
{
Write-Verbose "Navigating to $url"
$global:ie.Navigate($url)
WaitForPage $delayTime
}
Function WaitForPage([int] $delayTime = 100)
{
$loaded = $false
while ($loaded -eq $false) {
[System.Threading.Thread]::Sleep($delayTime)
#If the browser is not busy, the page is loaded
if (-not $global:ie.Busy)
{
$loaded = $true
}
}
$global:doc = $global:ie.Document
}
Function SetElementValueByName($name, $value, [int] $position = 0) {
if ($global:doc -eq $null) {
Write-Error "Document is null"
break
}
$elements = #($global:doc.getElementsByName($name))
if ($elements.Count -ne 0) {
$elements[$position].Value = $value
}
else {
Write-Warning "Couldn't find any element with name ""$name"""
}
}
Function ClickElementById($id)
{
$element = $global:doc.getElementById($id)
if ($element -ne $null) {
$element.Click()
WaitForPage
}
else {
Write-Error "Couldn't find element with id ""$id"""
break
}
}
Function ClickElementByName($name, [int] $position = 0)
{
if ($global:doc -eq $null) {
Write-Error "Document is null"
break
}
$elements = #($global:doc.getElementsByName($name))
if ($elements.Count -ne 0) {
$elements[$position].Click()
WaitForPage
}
else {
Write-Error "Couldn't find element with name ""$name"" at position ""$position"""
break
}
}
Function ClickElementByTagName($name, [int] $position = 0)
{
if ($global:doc -eq $null) {
Write-Error "Document is null"
break
}
$elements = #($global:doc.getElementsByTagName($name))
if ($elements.Count -ne 0) {
$elements[$position].Click()
WaitForPage
}
else {
Write-Error "Couldn't find element with tag name ""$name"" at position ""$position"""
break
}
}
#Entry point
# Setup references to IE
$global:ie = New-Object -com "InternetExplorer.Application"
$global:ie.Navigate("about:blank")

# Release resources
$global:ie.Quit()
$global:ie = $null
I had the same issue. I manually opened powershell and executed my script and I received "WebPage.ps1 cannot be loaded because running scripts is disabled on this system.".
You have to allow scripts to run
Execute the below in PowerShell
Set-ExecutionPolicy RemoteSigned -Scope LocalMachine
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.
