good evening

I need to extract parts of a .txt file

I wonder if you can do this with powershell.

The file that I need to read is attached, I need only extract this information as follows:


Server Blade #1 Information:
        Product Name: ProLiant BL460c Gen8
        Serial Number: BRC31939CV
        Server Name: EBR001001-311
        CPU 1:  Intel(R) Xeon(R) CPU E5-2680 0 @ 2.70GHz (8 cores)
        Memory: 262144 MB

#1           EBR001001-311                 ProLiant BL460c Gen8   BRC31939CV      Intel(R) Xeon(R) CPU E5-2680 0 @ 2.70GHz (8 cores)   262144 MB


thank you

It can be done, but your question is a little under-defined for actually writing a script.

Is your goal to output only the line with the extracted field information, in that order? Did you want to label the columns of the output? Do you want to output tab-delimited fields. Are you looking for the very first entry in the file or are you looking for a particular name. Does it make sense to convert the entire input file to an object collection that can be used elsewhere in PowerShell, or do you just want unlabeled items in an array?

This writes the results to the pipeline as custom objects with the properties you want. You can pipe the output through whatever you want, like Format-Table, Format-List, Export-Csv, ...
$InputFile = 'C:\Temp\EHP1.txt'

Switch -regex -File $InputFile {
	'\AServer Blade #(?<Blade>\d+) Information:\Z' {
		$Result = '' | Select-Object -Property 'Blade', 'ServerName', 'ProductName', 'SerialNumber', 'CPU', 'Memory'
		$Result.Blade = $Matches['Blade']
	}
	'\A\s+Server Name:\s*(?<ServerName>\S+)\s*\Z' {$Result.ServerName = $Matches['ServerName']}
	'\A\s+Product Name:\s*(?<ProductName>.*?)\s*\Z' {$Result.ProductName = $Matches['ProductName']}
	'\A\s+Serial Number:\s*(?<SerialNumber>\S+)\s*\Z' {$Result.SerialNumber = $Matches['SerialNumber']}
	'\A\s+CPU 1:\s*(?<CPU>.*?)\s*\Z' {$Result.CPU = $Matches['CPU']}
	'\A\s+Memory:\s*(?<Memory>\d+)\s+.*\Z' {
		$Result.Memory = $Matches['Memory']
		$Result
	}
}

Good Morning,
Perfect, the result was the same, very good.

If I need the information in columns, you can do?

So I have both formats.

I appreciate the help

This format is possible?

Blade      Servername           ProductName              SerialNumber                        CPU             Memoria                              
  1       EBR001001-011       Prolianr BL460c             BRC510671T      Intel(R) Xeon(R) CPU...    327680
  2       EEC002002-101       ProLiant BL460c Gen8        BRC510671K      Intel(R) Xeon(R) ...       262144

As I said: you can use anything that PS offers in terms of formatting, or you can use Export-Csv to process that further in Excel or wherever.
For a formatted table, use Format-Table; this should fit into a standard 120 character wide PS console:
.\Whatever.ps1 | Format-Table -AutoSize

A final information.

I need to read multiple files automatically in the same directory and generate a single output?

I have 8 files:

EHP1.txt
EHP2.txt
EHP3.txt
...

It's possible ?

Now has an additional column "File" with the file name from which the row came from.
$InputFile = 'C:\Temp\EHP{0}.txt'
1..8 | ForEach-Object {
	$FileName = $InputFile -f $_
	Switch -regex -File $FileName {
		'\AServer Blade #(?<Blade>\d+) Information:\Z' {
			$Result = '' | Select-Object -Property 'File', 'Blade', 'ServerName', 'ProductName', 'SerialNumber', 'CPU', 'Memory'
			$Result.File = [IO.Path]::GetFileName($FileName)
			$Result.Blade = $Matches['Blade']
		}
		'\A\s+Server Name:\s*(?<ServerName>\S+)\s*\Z' {$Result.ServerName = $Matches['ServerName']}
		'\A\s+Product Name:\s*(?<ProductName>.*?)\s*\Z' {$Result.ProductName = $Matches['ProductName']}
		'\A\s+Serial Number:\s*(?<SerialNumber>\S+)\s*\Z' {$Result.SerialNumber = $Matches['SerialNumber']}
		'\A\s+CPU 1:\s*(?<CPU>.*?)\s*\Z' {$Result.CPU = $Matches['CPU']}
		'\A\s+Memory:\s*(?<Memory>\d+)\s+.*\Z' {
			$Result.Memory = $Matches['Memory']
			$Result
		}
	}
}
