I'm trying to build a Powershell script that uses the Invoke-Item cmdlet once I've found the files using the following script:
gci -Recurse -File *.xls* C:\folder_example\' | sort LastWriteTime | Select -last 2 |
I'm not sure how best to implement the Invoke-Item cmdlet from here?
In its simplest usage, Invoke-Item (aliased as ii) just needs a path given to it either through pipeline or through a parameter.
In this case, it could be as simple as adding | Invoke-Item to the end of your command:
gci -Recurse -File *.xls* C:\folder_example\ | sort LastWriteTime | select -Last 2 | Invoke-Item
One thing I will mention, is that I have found that certain programs cannot handle a bunch of files thrown at them in quick succession like this script will do.
I usually run into this when trying to open a bunch of files in Notepad++.
I'm going to simplify the command a bit just to keep it short...but usually one of these two changes will fix my problem:
Get-ChildItem -Filter *.xls* | ForEach-Object { Invoke-Item $_.FullName }
Placing the call into a ForEach-Object script block will sometimes fix this. I'm not 100% why this fixes it, I have some theories but that's all they are, so I will keep them out of this answer. But it always fixes the issue for me when using Invoke-Item on Notepad++ files.
Some programs, like Excel, have a start up splash screen and some lag before they eventually open. So you could always throw a sleep in there just to help slow things down a bit in case you are still having trouble:
Get-ChildItem -Filter *.xls* | ForEach-Object { Start-Sleep 0.1; Invoke-Item $_.FullName }
That will add a small 100ms pause just to give whatever application you are running to have a little time to process.

I'm playing with malware in a VM and every script I try gets stuck. Basically I need to run every .exe in a folder. Tried batch files using start, powershell, etc. The issue happens when AV moves some file to quarentine, or some process keep running then the script doesn't jump to the next one.
CMD start works but shows popups when doesn't find some file, then you have to keep clicking to jump to the next file.
These works but get stuck after a while:
Get-ChildItem 'C:\Users\LAB\Desktop\test' | ForEach-Object {
>> & $_.FullName
>> }
Same here:
for %%v in ("C:\Users\LAB\Desktop\test\*.exe") do start "" "%%~v"
and here:
for %%i in (C:\Users\LAB\Desktop\test\*.exe) do %%i
You need to provide some form of code to allow us to help you troubleshoot it; this is not a request a script page.
Anyways, you would be looking at something like this:
#Assuming the .exe's are located in C Root.
Get-ChildItem -Path C:\ | Where-Object {$_.Extension -like ".exe"}| Foreach {Start-Process $_.FullName}
#In Ps, we like to filter as far left as possible for faster results.
Get-ChildItem -Path C:\ -File "*.exe" | Foreach {Start-Process $_.FullName}
#Running the commands as jobs so it doesnt wait on any to finish before running the next.
Start-Job { Get-ChildItem -Path C:\ -File "*.exe" | Foreach {Start-Process $_.FullName} }
Start-Sleep 2
Get-Job | Remove-Job

I´m currently running in the issue that my Rundeck Job fails cause it write a verbose message. Is there any possibility to change this behavior from rundeck?
My Job is a basic power shell command:
Get-ChildItem "\\server\folder" -Recurse -File | Where CreationTime -lt (Get-Date).AddDays(-365) | Remove-Item -Force -Verbose
Without the -verbose I don´t see which file was deleted, but I´d like to see this.
Someone any idea?
You can attach to your step a quiet output filter, that filter need a regex to catch the lines that you don't need, you can use this tool to test your regex definitions.
I created simple nagios plugin check_log.ps1 to check log file on windows machine. It works in way that make copy content of log and in next time look for specified string in difference between copy of log and original log file.
The problem is that sometimes in random moments check_log.ps1 locks log file so it cause stop of the application which create log file.
Generally plugin use original log file in two places
# compare content of $Logfile and $Oldlog, save diff to $tempdiff
Compare-Object -ReferenceObject (Get-Content -Path $Logfile) -DifferenceObject (Get-Content -Path $Oldlog) | Select-Object -Property InputObject > $tempdiff
# override file $Oldlog using conetent of $Logfile
Copy-Item $Logfile $Oldlog
I make test. In one PS session I run while($true) { [string]"test" >> C:\test\test.log }, in second session I run plugin C:\test\check_log.ps1 C:\test\test.log C:\test\Old_log.log test
I'm not fully sure if my test is correct but I think that Copy-Item command cause problem. When I comment this line in script I don't see any errors in terminals. I tested some custom functions to copy file which I found in internet but I din't find solution for my problem.
Do you have an idea how to make it work fully?
if you think the copy-item is locking the file, try reading the content and then saving it to another location. Something like this:
Get-Content $Logfile | Set-Content $Oldlog
I have a pretty neat mess of batch/python scripts that install a program called MATRIS, followed by about 15 exe updates.
Around 11 of these updates open a window telling me the that the update was successful.
Now it would be really fun to run a batch or powershell script which closes all of these windows for me.
The last thing I tried was Get-Process | Where-Object {$_.Path -like "MatrisInstaller.APCIPLUS"} | Stop-Process -WhatIf
I wasn't sure if it was the name as read in task manager, or like the title of the window, but I tried both.
Please note that a couple of these are (32 bit) - I'm not sure if that would impact the script.
I was able to run tasklist followed by kill {PID} but PIDs change: I'm not sure how to script it.
Please reply if you need any clarification, I've historically been poor at wording my questions.
In your example, Path is pointing to the executable file on disk, so while possible to use (if it is consistent), it won't match the name you find in the processes tab of Task Manager. Typically, people will use the name as shown on the Details tab of Task manager. For example, with Outlook on my system, these three possibilities are:
Path: C:\Program Files\Microsoft Office\Office16\OUTLOOK.EXE
Processes tab: Microsoft Outlook
Details tab: outlook.exe
So, you need a command like this:
Get-Process | Where Name -eq 'Outlook' | Stop-Process
or, better:
Get-Process -Name 'Outlook' | Stop-Process
Note that PowerShell expects you to remove the '.exe' you see in Task manager.
EDIT: Additional technique
If you know the names of the processes, then you can simplify your script by doing something like this:
$processList = "Process1","Process2","Process3" # Add all process names to the list
$processList |
ForEach-Object {
Get-Process -Name $_ | Stop-Process
}
You were almost there, just need to change "Path" to "ProcessName" like so:
Get-Process | Where-Object {$_.ProcessName -like "MatrisInstaller.APCIPLUS"} | Stop-Process -WhatIf
I'm trying to build a function that will show me all path's where a certain filename is located. The function would take one parameter, that being the file name.
The result would be either a list of all paths, or a message saying there's no such file on the system.
I'm new to Powershell, and I'm not getting the syntax just yet.
I've tried this:
Get-ChildItem -Path -Include notepad.exe
But that threw an error message. I'm currently trying:
$i="notepad.exe"
Foreach ($i in Get-ChildItem c:\ -Recurse){echo -Path}
Started that now, it's still running, don't know what'll happen, really.
EDIT: echo'd an enormous amount of lines that just say "-Path"...
Can anybody help with this problem? I'm running Powershell 1.0 by the way.
So, to explain what I wish to see when executing this command, here is an example of what I expect after looking for *.txt:
C:/foo.txt
C:/A/foobar.txt
C:/A1/foo.txt
And so on, listing the path to all .txt files on my harddrive. Only the paths, one per line, no extra info needed.
EDIT2:
I've done it. I'm gonna leave this question up for those who make look for this in the future.
The function I used was this(this specific example will hand you a list of all .zip files on your harddrive, edit where needed):
Get-ChildItem -Path c:\ -Include "*.zip" -Recurse -Force -Name > c:\listOfPaths.txt
This created a file called listOfPaths.txt on my C:\ folder and this contained a list of all occurences of any file ending with .zip in all subfolders of my harddrive.
The "c:\" bit isn't mentioned, but I don't mind.
EDIT3:
thanks capar for a more complete version.
Here is capar's code(or how I got it to work, since Get-Children doesn't work in 1.0)
Get-ChildItem -Path c:\ -Recurse *.txt | Select-Object -Property FullName
Since it's Friday night, I decided to play with Power Shell to see if I can help :)
This comes pretty close to what you are asking for I think:
Get-ChildItem -Path c:\ -Recurse *.txt | Select-Object -Property FullName
If it helps, this command will list the properties of any object that will be returned by Get-ChildItem:
Get-ChildItem | Get-Member
ls c:\ -r | ? {$_.name -eq "notepad.exe"}
Get-Children is not recognized in Powershell V3 either. It would be great if someone removed that bad example.
As a warning to anyone searching for files: C:\ on today's hard drives will take a long time to run. You are well advised to narrow your search as much as you can. Since your folder structure might include spaces or special characters, use the typewriter quote (") or apostrophe (') delimeters.
