Selected Answer: D

Options A, B, and C are incorrect for the following reasons: A. tail is not a PowerShell command (it's a Unix/Linux command). B. info is not a recognized command or parameter and the syntax is incorrect. C. The syntax is incorrect because it uses | (pipe) followed by extract.txt, which is not a command. Also, get content should be get-content.

Doesn't powershell use a pipeline to the the output file instead of a > ?

Using the pipe '|' is to send an object through to the next command (i.e., "Get-Content myfile.txt -Last 10000 | Select -First 1" would first get the last 10,000 lines of the file, and then you are selecting the first object of the 10,000 with "Select -First 1"). Using '>' sends text to a file (overwrites current file if the name already exists). If you use '>>', it appends the text you are sending to the file instead of overwrites.

Selected Answer: D

well "tail" is linux, and Powershell hyphenates commands like get-content. So, not knowing the right command, the bottom one is the only one that looks like a real Powershell command anyway

Selected Answer: D

This script uses the get-content cmdlet to read the contents of the Massivelog.log file and then selects the last 10,000 lines using the -Last parameter. The output is then redirected to a new file called extract.txt using the > operator.

The closest answer is D. The actual command should be: get-content './Massivelog.log' -Last 10000 > extract.txt

The cmdlet feels like a giveaway to me. I thought tails was exclusive to Linux.

PowerShell uses Verb-Noun syntax for cmdlets. D ( Get-Content ) is correcto. https://learn.microsoft.com/en-us/powershell/scripting/developer/cmdlet/approved-verbs-for-windows-powershell-commands?view=powershell-7.2
