PowerShell remove line feed

Line feed is useful in some ways like formatting lines so it will be easy to read if there’s a line in between the other line.
But there are also instances that line feed might be annoying or simply we need to get rid of it since it’s not desired on the output.
There instances that Out-string parameter in PowerShell will append a line feed on its output.
Or if you take the input or output from other sources but want to remove the line feed, PowerShell can remove the line feed without any hassle.
Code below is using PowerShell to remove line feed from an input, the input could either be a text file or a string pipe to another variable.
$string_with_line_feed -replace "`n|`r"
`n -  backtick with n refers to the line feed character `r – backtick with r refers to the carriage return
Or the code above can be written as follows:
$string_with_line_feed -replace "`n|"
So, basically line feed is replace with nothing. But for readability and to avoid confusion it’s better to …

PowerShell Test Port Forwarding

Port forwarding is necessary if the device is that needs to connect to the unsecured world of the Internet.
Of course, before opening port or doing any port forwarding make sure that security is in place. Firewall rules, software configuration are properly set, up-to-date anti-virus and other settings that needs to be done to secure the system.
PowerShell can test whether a remote port is open or a Port Forwarding rules on either on the Firewall or router is set correctly.
Here’s a one liner code, to check whether the Port is open or not.
Both one line code below does the same thing, check whether the Port is open or not.
1 . New-Object System.Net.Sockets.TCPClient -ArgumentList "Remote.Public.IP.Address", 3389
2. Test-NetConnection -Port 80 -InformationLevel Detailed

Replace the port number, with any port number to be tested.
If the connected property on the displayed output is true, then the port is open.

Svchost process in task manager

Svchost.exe contains generic host processes.

If the svchost.exe is accidentally close or intentionally close, then the system might crash or shutdown.

To kill or close a process forcefully via command line can be done using taskkill command plus the process id.

Ex: Taskkill /pid 1234

How to know exactly which service or process the svchost is running?

To check the pid and the process that svchost is running, type:

tasklist /svc

Tasklist /svc command will display the image name, pid and the services.

Output example for tasklist /svc command:

svchost.exe                   1172 EventSystem, fdPHost, FontCache, netprofm,
                                   nsi, W32Time, WdiServiceHost
svchost.exe                   1200 Appinfo, BITS, Browser, CertPropSvc,

Copy folder/file to multiple folders

Copy a single folder to multiple folders?

Copy a file to multiple folders?

This can be done easily using PowerShell script.

Script below requires PS 3.0, but it can easily be tweak for other version.

Here's the script:

#++++++++++++++++++++++++++++++
$source_folder="D:\xfolder\United Folders"
dir -Directory "D:\Unity\Project_016\" | ForEach-Object {
write-host $_.fullname
Copy-Item -Path $source_folder -Destination $_.FullName
}

#++++++++++++++++++++++++++++++

What the script does is the $source_folder is to be copied to all folders in the destination.

Basically, the "United Folders" is to be copied to the root of the sub folder in destination folder which is "D:\Unity\Project_016\".

Example:
D:\Unity\Project_016\01
D:\Unity\Project_016\02
D:\Unity\Project_016\03

After executing the script, the folders will look like this:
D:\Unity\Project_016\01\United Folders
D:\Unity\Project_016\02\United Folders
D:\Unity\Project_016\03\United Folders

Active Directory GPO apply to forest

How to apply GPO to whole forest?

1. Open GPMC (Group Policy Management Console) and create a GPO for a single domain.

2. Link the GPO to other domains in the forest.
   Right click each domain and select "Link an Existing GPO Here" then select the GPO that will be applied to all domains in the forest.

3. If everything works fine, then you're a lucky man.


Before rolling out a GPO create a test Organizational Unit and create Active Directory user accounts for test purposes.

Then apply the GPO to the OU.

If it works properly then there's a good chance that it will work smoothly to all users but it's not a guarantee that it will work correctly to all users.

If the GPO is critically needed to be applied to all users and testing works okay, roll out the GPO and troubleshoot issues that may occur.

If no problem arises, then drink a cup of coffee and consider yourself "lucky".

If the GPO is not yet tested and you are not sure whether it will havoc the Active Directory …

Gci d:\WorkFolder $_ | Where-Object {
$extension -contains $_.Extension
} | % {Copy-Item $_.FullName d:\mix_backup}
To read files with specified filename extension.
$extension = ('.pdf', '.docx', '.txt')
Dir d:\WorkFolder $_ | Where-Object {
$extension -contains $_.Extension
}

or
$extension = ('.pdf', '.docx', '.txt')
Gci d:\WorkFolder $_ | Where-Object {
$extension -contains $_.Extension
} | % {write-host $_.FullName }

Copying files with the long path will result to an error.

Below is the modified code that uses robocopy to copy files with long paths.

Do not interchange source and destination when using robocopy, the files will be overwritten.
