Is there a way to simulate the *nix tail command on the Windows command line? I have a file and I want a way to snip off the first n lines of text. For example:

    Here is a fast native head command that gives you the first 9 lines in DOS.

    findstr /n "." myfile.txt | findstr "^.:"
    

    The first 2 characters on each line will be the line number.

    FWIW, for those just needing to snip off an indeterminate number of records from the head of the file, more > works well. This is useful just to have a smaller file to work with in the early stages of developing something.

  • IF you have Windows PowerShell installed (I think it's included since XP) you can just run from cmd.exe:

    Head Command:

    powershell -command "& {Get-Content *filename* -TotalCount *n*}"
    

    Tail Command:

    powershell -command "& {Get-Content *filename* | Select-Object -last *n*}"
    

    or, directly from PowerShell:

    Get-Content *filename* -TotalCount *n*
    Get-Content *filename* | Select-Object -last *n*
    


    update

    PowerShell 3.0 (Windows 8 and higher) added Tail command with alias Last. Head and First aliases to TotalCount were also added.

    So, commands can be re-written as

    Get-Content *filename* -Head *n*
    Get-Content *filename* -Tail *n*

    Well, this will do it, but it's about as fast as it looks (roughly O(n*m), where n is the number of lines to display and m is the total number of lines in the file):

    for /l %l in (1,1,10) do @for /f "tokens=1,2* delims=:" %a in ('findstr /n /r "^" filename ^| findstr /r "^%l:"') do @echo %b
    

    Where "10" is the number of lines you want to print, and "filename" is the name of the file.

    Powershell:

    Get-Content C:\logs\result.txt -Tail 10
    
    Get-Content C:\logs\result.txt -wait (monitor the tail)

    There is a resource kit that can be downloaded from here: http://www.microsoft.com/downloads/en/confirmation.aspx?familyId=9d467a69-57ff-4ae7-96ee-b18c4790cffd&displayLang=en

    It contains a tail.exe tool but it is only compatible with some Windows versions
