PowerShell search text file contents


PowerShell code below will search recursively all text file on the path specified. If the pattern matches on the text file, the contents will be copied and all matching patterns will be consolidated on a single file.

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

Get-ChildItem -Path "d:\all_text_files \" -recurse | ForEach-Object {

  @'

= = =>>>The file name - {0}

{1}

- - - - - - -

`r`n

'@ -f $_.Name, (Get-Content $_.FullName )

}  | Select-String -pattern "router" | Out-File 'd:\d_output\output.txt'

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

Code explanation:

Get-ChildItem -Path "d:\txt notes\" -recurse | ForEach-Object  >>> Get all the items recursively on the path specified and for each object process each object

  @'  '@ >>> PowerShell string format that any text or string between the @ symbol will be process exactly as it is displayed, it’s like what you see is what you get.

{0} {1} >>> are place holders, in which the value we be replaced as each object is processed by the for each loop

-f >>> is a format operator which utilizes the {0} and {1} place holders

 $_.Name, (Get-Content $_.FullName ) >>> $_.Name will take place {0} and Get-Content $_.Fullname takes the place holder {1}

| Select-String -pattern "router"  >>> the pattern or the string that will be search  on each file

| Out-File 'd:\d_output\output.txt' >>> any matching pattern will be kept on this text file


If you need to list only the filenames and don't need to copy the contents the code above can be tweak to this edited code below:


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

Get-ChildItem -Path "d:\all_text_files \" -recurse | ForEach-Object {

  @'

= = =>>>The file name - {0}

`r`n
- - - - - - -


'@ -f $_.Name

}  | Select-String -pattern "router" | Out-File 'd:\d_output\filename_output.txt'

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

The format  (-f) operator needs {0} only since only the filename will be processed.

The code can also be used to search for eml files, since eml files are text files also. I think it might work also on  xml files but I haven't test.



Happy scripting.

Cheers..till next time.

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.

Robocopy is free it can be accessed from command line. No need to install the resource kit tool if the operating system is Windows 7 or newer version.

Copy files with selected file extension using PowerShell and Robocopy:

$extension = ('.pdf', '.jpg', '.txt')
gci d:\WorkFolde…

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…
