PowerShell Add Custom Result Property


PowerShell has its own or default format of displaying the results or the output of the cmdlets or PowerShell commands.

However, PowerShell is customisable, and the output property can be modified.

Example below, gets the name of the file and display the date only without the time.

PowerShell code snippet below filter a single  and gets its lastwrite date.

get-childitem "C:\Users\ps_testing\Documents" -filter IMXP2611.jpg -recurse |  select Directory, Name, @{Name="LastWriteDate";
  Expression={$_.LastWriteTime.ToString("yyyy-MM-dd")}} | ft -wrap


This can be modified using wildchars like "*", which filters all "jpg" regardless of filename.

get-childitem "C:\Users\ps_testing\Documents" -filter *.jpg -recurse |  select Directory, Name, @{Name="LastWriteDate";
  Expression={$_.LastWriteTime.ToString("yyyy-MM-dd")}} | ft -wrap
LastWriteDate == is a custom label for the output

yyyy-MM-dd == is a custom format that display only the date in year, month and day format

 @{Name="LastWriteDate";   Expression={$_.LastWriteTime.ToString("yyyy-MM-dd")}} == is where the customisation takes place



Sample Output:

Directory                      Name               LastWriteDate 
---------                           ----                   -------------
C:\Users\ ps_testing \Documents IMXP2611.jpg 2019-09-22 


Well, that is just a basic example. Play around with the “expression” property for other possible options.

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.

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.

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.
