PowerShell extract shared folder permissions


How to extract list of shared folders permissions?

If the path of shared folder and its sub folders are not too long, it will be smooth and easy to get the security permissions.

If the paths are quite long, then it will be a challenge.

Robocopy.exe a command line tool, that is able to list folder and sub folders even the path are too long.

Used the robocopy script from this link, to list all the files, folder and sub folders and save to a text file.

But the robocopy output, will have a very detailed output that includes complete file names, the number of files on each folder and other details.

To list the shared folder security permissions on PowerShell using the Get-Acl cmdlet; what is needed is just the path to the folder.

So from the text file of robocopy output, need to extract the path directory for all the folders.

Using the PowerShell script from this link  (http://powershell.com/cs/forums/t/12206.aspx):

=====================
#from this link
#http://powershell.com/cs/forums/t/12206.aspx
$pathToFile="d:\robocopy_folder_list.txt"
$flag=0
Get-Content $pathToFile |
foreach {
    Switch -Wildcard ($_){
        "*New Dir*" {$flag=1}
        "*New File*" {$flag=0}
    }
    if ($flag -eq 1){
        Out-File d:\fxresults.txt -InputObject $_ -Append
    }
}
=====================

Script above will extract path directories.

The extracted output will be like this:

New Dir         63    c:\shared\
New Dir         34    c:\shared\1\IconRestorer\Languages\

List can go on up to thousands of lines depend on how many folders on the list.

The "New Dir and the number" is not needed, and it will be tedious to delete it line by line.

To clean up this, I did it manually with the aid of Notepad++, not so hard.

I just open the text file using Notepad++ and used the Alt+Shift method to select the two columns and use page down to delete.

After cleaning up the text file, save it to another file name and what should remain is just the path.

c:\shared\
c:\shared\1\IconRestorer\Languages\

To get the shared folder permissions for all the folders.

Open the text file using PowerShell and use Get-ACL cmdlet.

Here's the simple code snippet to list the security permissions for all the sub folders.

=====================================

$pathToFile = "d:\extracted_directory_path_results.txt"

$xLines = Get-Content $pathToFile

ForEach ($Line In $xLines)

{

$xstr = $Line.ToString()
#Write-Host ($xstr.Trim())

#need to trim the string or Get-Acl will throw an error
#this line will just display the output
Get-ACL($xstr.Trim()) | Format-list

#will save the result to a text file
#Get-ACL ($xstr.Trim()) | Format-list | out-file d:\Folder_Security_List.txt -Append

}
=====================================

It's a 3 step method that cost no money, but it does the job for listing security permissions for hundreds or thousands of folder and sub folders within a few minutes.

The PowerShell script should be read with administrative privileges, or else it will not be able to get the security permissions.


If there's a shorter way for doing this, please share it.

Cheers!!

WMIC get computer name

WMIC get computer model, manufacturer, computer name and  username. WMIC is a command-line tool and that can generate information about computer model, its manufacturer, its username and other informations depending on the parameters provided. Why would you need a command line tool if there’s a GUI to check? If you have 20 or 100 computers, or even more. It’s quite a big task just checking the GUI to check the computer model and username. If you have remote computers, you need to delegate someone in the remote office or location to check. Or you can just write a batch file or script to automate the task. Here’s the code below on how get computer model, manufacturer and the username. Open an elevated command prompt and type:     wmic computersystem get "Model","Manufacturer", "Name", "UserName" Just copy and paste the code above, the word “computersystem” does not need to be change to a computer name.

Notepad++ convert multiple lines to a single line and vice versa

Notepad++ is an awesome text editing tool, it can accept regex to process the text data. If the data is in a “.csv” format or comma separated values which is basically just a text file that can either be opened using a text editor, excel or even word. Notepad++ can process the contents of the file using regex. Example if the data has multiple rows or lines, and what is needed is to convert the whole lines of data into a single line. Notepad++ can easily do it using regex. However, if the data is on a single line and it needs to be converted into multiple lines or rows then regex can also be used for this case. Here’s an example on how to convert multiple rows or lines into a single line. Example data: Multiple rows, just a sample data. Press Ctrl+H, and  on "Find what" type: [\r\n]+ and on "Replace with" type with: , (white space) --white space is needed if need to have a space in between the data. See image below, "Regular Expression" must be se

Print error 016-799 - Fuji Film Xerox

016-799 Fuji Xerox or Fuji Film print error code. That shows a description error as “Print instruction Fail detected in decomposer.” The error code and error description are alien languages for users and even system administrators who are not familiar with Fuji Xerox error code. The error code is quite simple and easy to fix, if the job print goes to the printer but print out doesn’t come out. So, basically the print job was received by the printer, but the printer just doesn’t know what type of paper or what size to use or which tray to utilize for the print out. In some instances, this is just a paper mismatch but the error description; if using Windows 10 to print does not exactly points to what is the issue. First thing to check, is the paper size selected by the user to print. Example, if the printer configuration is A3 and A4 sizes only. But then the person printing the file accidentally chooses “A4 Cover” then this error 016-799 will occur.
