Powershell get folder names


Messing up with folders in Powershell?

Got a thousand and hundreds of folders on your drive and you want to get the folder names or just having some free time and you want to organize it?

Powershell will save time to organize those folders and will save time on searching and finding information.

Organizing folders or even organizing your own activities in life makes it easier and systematic.
How to mess up with folders in Powershell? And get the data that you wanted.

Powershell provides a relatively quick and easy way to list folders.

Open Powershell ISE or the Powershell command prompt.

Or you are a command line junkie, dir command will be the first command that will cross your mind if you need to list folders in Windows and it also even works in Linux.

Since "dir" command does a beautiful job of listing folders and files, the outout can easily be pipe to Powershell for further processing.

Try this command in Powershell ISE or Powershell command prompt:

dir d:\ | where-object {$_.PsIsContainer -eq $true} | select-object name

Sample output:


PS C:\Users\user01> dir d:\ | where-object {$_.PsIsContainer -eq $true} | select-object name

Name
----
64 bit win 2012
70-417 html notes win2012


It will list the folder names on the drive specified on the command.


To get the last write time for each folder use this command:

dir d:\ | where-object {$_.PsIsContainer -eq $true} | select-object name,lastwritetime

Sample Output:

Name                          LastWriteTime
----                          -------------

64 bit win 2012               11/14/2012 9:48:40 PM
70-417 html notes win2012     5/30/2015 4:44:57 PM


To include the path for each folder type this command:

dir d:\ | where-object {$_.PsIsContainer -eq $true} | select-object fullname


Sample Output:

Name
----
D:\64 bit win 2012
D:\70-417 html notes win2012

If the output of the commands is just overwhelming, too much information that you can't even process is good as nothing.


If there are hundreds or thousands of data, filter the output by this command:

dir d:\ | where-object {$_.PsIsContainer -eq $true} |  Select-object name | where {$_.Name -like "70*"}


The "-like" operator will filter any folder names that starts with the word "70" on the folder name.


If you are looking for a folder name but you just remember a part of the folder name use this command:

dir d:\ | where-object {$_.PsIsContainer -eq $true} |  Select-object name | where {$_.Name -match "70*"}

The command will search for any folders that has "7" or "70" on each folder name.


Sample output of the command that uses "-match "70*":

Name
----
70-417 html notes win2012
70647
Intel Wireless LAN Driver Win7x86-64bit
New folder_70_
win
wireless lan driver win7x86-64bit

--------------------------------------------------

 "dir" and "ls" command in Powershell is an alias for Get-ChildItem or gci for short.


That's all, till next time. Try it messed up with the folder names. The command does not remove, delete or rename the folders so you are safe to play with it.



Cheers..Happy coding!!!

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++ 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. ...
