PowerShell Insert Multiple Lines or text to another file dynamically

Copying and pasting text to another file is a common thing to do, copy and paste done. Boom!
In PowerShell scripting copying and pasting text from one file to another dynamically isn’t as easy as it is done in a spreadsheet or document. Dynamically while the code is running  and doing things in the background without human intervention.
As the odds say, if there’s a will there’s a way. And making things efficient and easy is a good way in life.
If ever a scenario occurs that you need to copy text or lines in a file from one file to another, without breaking the code execution. Script below works just fine. Just insert the code where it is needed.

PowerShell code snippet:
#================================
$reader=[System.IO.File]::OpenText("D:\test-read-paste\main1.txt") #get-content can also be used
$lineNumberx=3 #adjust this number where you need to start inserting the text
#Loop line by line and process while($null-ne ($line=$reader.ReadLine())) {
$textToAdd=$line
$newLineToAd…

Working with text in PowerShell

Working with a text file or text format in PowerShell is a good thing to learn.
Getting or monitoring output from PowerShell for further processing or analysis and having it in text file format can easily be imported to other applications.
Working with text or other format, requires these basic operations: Save, Overwrite, Append and Save As.
Save, overwrite, append and save as is a common operation when editing word documents, excel file and other office applications since it’s freely available on the menu of the application. But can we do this in PowerShell? The answer is a resounding, yes.


So, how to do it? Examples below shows how to work with text files in PowerShell and do the operation mentioned above.

Equivalent operations for Save, Overwrite, Append and Save As in PowerShell:

Change Password of Scheduled Tasks in PowerShell

How to change Tasks Scheduler password?
How to set a new password for scheduled tasks in Windows Task Scheduler using a script?
PowerShell is always a friend to cure laziness in an effective and efficient way.
Of course, not all things can be done by automation. Sometimes manual method is more applicable and a secure method on some scenario.
If you have a few servers that has scheduled tasks on it and need to change the password occasionally to comply with cyber security policies, changing tasks manually might be painful and chances are some tasks might be missed.
Changing the password in Task Scheduler using PowerShell is an efficient method if the task has to be done repeatedly on a few servers.
To change the password, the TaskName must be known since it’s an input or a required field for the command used to change the Task password.

PowerShell registry keys basic operation

Working with registry keys is good and bad.
Good if you know exactly what you are doing, bad if you are just experimenting and you mess up the entire system.
Anyway, virtual machines will always save the day during test or experiment stage. Once everything is okay then deploy to the actual or production environment. If the test goes haywire, just trash the VM and start all over again.
Below are just simple and basic commands in PowerShell to query or get data from the registry.
This command below will list all the software listed on HKCU\Software path.
Get-ChildItem -Path HKCU:\Software
It’s quite useful to run it sometimes, so you will know what software is inside your system.
Below will list the user shell folders on the system.
Get-itemproperty 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders'
Sample output:
AppData                                : C:\Users\Administrator\AppData\Roaming Local AppData                          : C:\Users\Administrator\A…

PowerShell get folder capacity

Get the folder capacity using PowerShell via the old-school method.
Old-school since we will utilize the native “dir” command, just like the good old days of DOS.
PowerShell dir command output is not the same with the native windows system32 dir command line just like in DOS system.
The output will be in bytes since it is from the command line but of course, if you are command line junkie it will be easy to read even if the capacity is written in bytes.
First, fire up notepad write the dir command plus the full folder path of the specified folder in which you like to monitor or want to know the capacity.
 dir “c:\users\dmusic\music folder 001”
The path is enclosed in quotes since the folder has spaces and save the notepad as a batch file with “.bat” extension.
Open PowerShell command line window or PowerShell ISE and type the following command:
#change the path to where the batch file was saved
$folder_base_cap = d:\read_folder_cap.bat 
$ folder_base_cap | Select-String "bytes&qu…
