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

    $newLineToAdd =  "`n" #line feed

        $fileContent = Get-Content 'd:\test-read-paste\main2.txt'
        $fileContent[$lineNumberx-1] += $newLineToAdd
    #$fileContent | Set-Content d:\test-read-paste\main2.txt

    #$fileContent = Get-Content 'd:\test-read-paste\main2.txt'
        $fileContent[$lineNumberx-1] += $textToAdd
        $fileContent | set-Content d:\test-read-paste\main2.txt


    $lineNumberx = $lineNumberx + 1
  
}

#================================

Main-1 Text file: (sample text only - reference file)



Main-2 Text file (Before Inserting Data)



Main-2 Text file (After Inserting Data or after running the PowerShell script)



Till next time..happy coding!!!

Copy a single file using robocopy

Copy a single file using robocopy from a local folder to a shared folder on the network.
A simple rule of thumb before any disaster strike, don't interchange the source and the destination.

If source and destination is mistakenly reverse, files might get overwritten. To avoid any loss of data do a test with a dummy file to ensure things work perfectly.
Robocopy [source][destination]   [file to be copied]
robocopy c:\local_c_folder  \\PC_network\shared_folder   file_to_be_copied_xx.txt
The command will be completed successfully provided the network access right has no issues.

Robocopy works quite good on large files. A simple copy or xcopy command will also work but the speed might vary.

However, if the file (ex. an ISO file) and is more than 4GB and the filesystem  of the thumbdrive or the storage is FAT system, then robocopy or any methods of copying will not work. Since FAT has a file size limitation of less than 3GB.

Robocopy is free it can be accessed from command line. No ne…

WMIC List printers

WMIC comes handy if you are a command line junkie.

To list printers via command line type:

wmic printer get name  = = = this will list all the printers installed on a workstation

To list the printer name and the port name of the printers, type this command:

wmic printer get name, portname

Type this command below to list the printer drivers:

wmic printer get name, drivername

To get the device id:

wmic printer get name, deviceid

You can deploy a batch file startup script to check which printer is installed on the computers and redirect the output to a shared folder.

PowerShell can also be used in conjunction with WMIC command:

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.
A sample output below will be generated if the co…
