To retrieve the specific number of lines from the beginning or the end of the file, you first need to get the content of the file using Get-Content and then need to pipeline the -First for retrieving the number of files from the beginning and -Last to retrieve the number of lines from the bottom.

Check the below example of retrieving the content of the first 10 lines.

Example

Get-Content D:\Temp\PowerShellaliases.txt -First 10

Output

PS C:\WINDOWS\system32> Get-Content D:\Temp\PowerShellaliases.txt -First 10
CommandType     Name                                               Version    Source
