为了完整起见，我将提到Powershell 3.0现在在Get-Content上有一个-Tail标志

Get-Content ./log.log -Tail 10

获取文件的最后10行

Get-Content ./log.log -Wait -Tail 10

获取文件的最后10行并等待更多

另外，对于那些*nix用户，请注意大多数系统将cat别名为Get-Content，因此这通常是可行的

cat ./log.log -Tail 10

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.

对于那些以“打字越少越好”为原则的管理员来说，下面是我能找到的最短版本:

gc filename -wai -ta 10

我使用了这里给出的一些答案，但只是提醒一下

Get-Content -Path Yourfile.log -Tail 30 -Wait 

会在一段时间后咀嚼记忆。一个同事在过去的一天里留下了这样一个“尾巴”，它高达800 MB。我不知道Unix尾巴是否也有同样的行为(但我怀疑)。所以短期使用是可以的，但要小心。

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

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。
