PowerShell Compare and Get Hash File

 Hash File comparison is a good thing to do, to make sure that file in transit, transferred, downloaded, or copied over is not corrupted or has been altered or modified.

PowerShell has a built-in module to do this that makes life easier and an easy task to do.

Here's an example code snippet to do this:

#Path location of the file

$file="C:\Users\User1\Downloads\Win10_22H2_EnglishInternational_x64.iso"

# Get the file hash

$hashSrc = Get-FileHash $file -Algorithm "SHA256"

write-output $hashSrc


#copy the Hash file 

$Display_hash_only = $hashSrc | Select-Object -Property Hash | ft -HideTableHeaders

Write-Output $Display_hash_only

Output of the write-output $hashSrc command, will show the Algorithm used, the Hash of the file and path location of the file.

Algorithm : SHA256 

Hash: AC5522F9DB9F4F432A1AADE69FEF268C8C0B5FD3F22D3A6987719752F8A7108 

 Path : C:\Users\User1\Downloads\Win10_22H2_EnglishInternational_x64.iso

 After getting the Hash File run this code snippet below to compare the string. Compare the original Hash file and the output of the Hash file from above script.

$source_hash_file = "3AC5522F9DB9F4F432A1AADE69FEF268C8C0B5FD3F22D3A6987719752F8A7108"

$to_compare_hash_file = "3AC5522F9DB9F4F432A1AADE69FEF268C8C0B5FD3F22D3A6987719752F8A7108"


#compare hash file ignore case 

$check = $to_compare_hash_file -eq $source_hash_file

Write-Output $check


#Compare if file hash matches

if ($check -eq "True") {

    Write-Output "File Hash Matches"

} else{

     Write-Output "File Hash does not Match"

}

That's it, if the Hash File Matches then the file is same as the original source file, however, if the Hash File does not match, then there's something wrong with the file.


Cheers! Take care. Till next Time.

Stay safe! and Keep things up!

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.

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. ...
