有许多有效的答案，但是，没有一个与linux中的tail具有相同的语法。下面的函数可以存储在$Home\Documents\PowerShell\Microsoft.PowerShell_profile中。Ps1的持久性(请参阅powershell概要文档了解更多详细信息)。

这允许你调用…

tail server.log
tail -n 5 server.log
tail -f server.log
tail -Follow -Lines 5 -Path server.log

这与Linux语法非常接近。

function tail {
<#
    .SYNOPSIS
        Get the last n lines of a text file.
    .PARAMETER Follow
        output appended data as the file grows
    .PARAMETER Lines
        output the last N lines (default: 10)
    .PARAMETER Path
        path to the text file
    .INPUTS
        System.Int
        IO.FileInfo
    .OUTPUTS
        System.String
    .EXAMPLE
        PS> tail c:\server.log
    .EXAMPLE
        PS> tail -f -n 20 c:\server.log
#>
    [CmdletBinding()]
    [OutputType('System.String')]
    Param(
        [Alias("f")]
        [parameter(Mandatory=$false)]
        [switch]$Follow,

        [Alias("n")]
        [parameter(Mandatory=$false)]
        [Int]$Lines = 10,

        [parameter(Mandatory=$true, Position=5)]
        [ValidateNotNullOrEmpty()]
        [IO.FileInfo]$Path
    )
    if ($Follow)
    {
        Get-Content -Path $Path -Tail $Lines -Wait
    }
    else
    {
        Get-Content -Path $Path -Tail $Lines
    }
}

只是对之前答案的补充。Get-Content定义了别名，例如，如果您习惯UNIX，您可能喜欢cat，还有type和gc。所以与其

Get-Content -Path <Path> -Wait -Tail 10

你可以写

# Print whole file and wait for appended lines and print them
cat <Path> -Wait
# Print last 10 lines and wait for appended lines and print them
cat <Path> -Tail 10 -Wait

PowerShell Community Extensions (PSCX)提供了Get-FileTail cmdlet。这看起来是一个适合这项任务的解决方案。注意:我没有尝试它与非常大的文件，但描述说，它有效地尾部内容，它是为大型日志文件设计的。

NAME
    Get-FileTail

SYNOPSIS
    PSCX Cmdlet: Tails the contents of a file - optionally waiting on new content.

SYNTAX
    Get-FileTail [-Path] <String[]> [-Count <Int32>] [-Encoding <EncodingParameter>] [-LineTerminator <String>] [-Wait] [<CommonParameters>]

    Get-FileTail [-LiteralPath] <String[]> [-Count <Int32>] [-Encoding <EncodingParameter>] [-LineTerminator <String>] [-Wait] [<CommonParameters>]

DESCRIPTION
    This implentation efficiently tails the cotents of a file by reading lines from the end rather then processing the entire file. This behavior is crucial for ef
    ficiently tailing large log files and large log files over a network.  You can also specify the Wait parameter to have the cmdlet wait and display new content
    as it is written to the file.  Use Ctrl+C to break out of the wait loop.  Note that if an encoding is not specified, the cmdlet will attempt to auto-detect the
     encoding by reading the first character from the file. If no character haven't been written to the file yet, the cmdlet will default to using Unicode encoding
    . You can override this behavior by explicitly specifying the encoding via the Encoding parameter.

尝试Windows Server 2003资源工具包工具

它包含一个tail.exe，可以在Windows系统上运行。

关于这个主题，我有一个关于多个文件的有用提示。

使用PowerShell 5.2 (Win7和Win10)跟踪单个日志文件(如Linux中的'tail -f')很容易(只需使用“Get-Content MyFile -Tail 1 -Wait”)。然而，同时查看多个日志文件似乎很复杂。PowerShell 7。x+然而，我发现了一个简单的方法，使用“Foreach-Object - parallel”。这将同时执行多个“Get-Content”命令。例如:

Get-ChildItem C:\logs\*.log | Foreach-Object -Parallel { Get-Content $_ -Tail 1 -Wait }
