PowerShell read text file at a specific or certain lines

Reading log files or text file is quite basic and log files should be reviewed or else recording the logs if of no point.

PowerShell code below read the 2nd line of a specific text file specified on the path.

 

$logs = get-content c:\dev\log1.txt 

"Line number 2 in log1.txt is: {0}" -f ($logs[2])

  

PowerShell code below uses a loop to read number of lines on a specific text file.



$logs = get-content c:\dev\log1.txt 

ForEach ($line_number in 0..10 ) {  "Line number $line_number is : {0}" -f ($logs[$line_number])}

  

Using above code, 0 is equal to line 1. 

So, to read the first line code should be like this:

  

$logs = get-content c:\dev\log1.txt 

"Line number 1 in log1.txt is: {0}" -f ($logs[0])

  

To read the last line:


$logs = get-content c:\dev\xtest.txt -Tail 1

$logs

  

If above command will return an empty output, just make sure that the text file does not have any empty spaces at the bottom of the file.

Cheers...till next time. Stay safe and keep praying that this pandemic will end.

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.

Print error 016-799 - Fuji Film Xerox

016-799 Fuji Xerox or Fuji Film print error code. That shows a description error as “Print instruction Fail detected in decomposer.” The error code and error description are alien languages for users and even system administrators who are not familiar with Fuji Xerox error code. The error code is quite simple and easy to fix, if the job print goes to the printer but print out doesn’t come out. So, basically the print job was received by the printer, but the printer just doesn’t know what type of paper or what size to use or which tray to utilize for the print out. In some instances, this is just a paper mismatch but the error description; if using Windows 10 to print does not exactly points to what is the issue. First thing to check, is the paper size selected by the user to print. Example, if the printer configuration is A3 and A4 sizes only. But then the person printing the file accidentally chooses “A4 Cover” then this error 016-799 will occur. ...
