如何使用參數從cmd.exe運行內部Powershell腳本函數

Question

我想在命令提示符下使用Powershell（.ps1）腳本而不使用此命令

   Powershell.exe -noexit Set-ExecutionPolicy Unrestricted -file "C:\Get-NetworkStatistics.ps1"

當前，此命令打開Powershell窗口。 我希望直接cmd使用此腳本並給我輸出。 可能嗎？

以下是我的Get-NetworkStatistics.ps1腳本。 請指導我有沒有辦法直接使用它？

function Get-NetworkStatistics {
<#
.SYNOPSIS
    Display current TCP/IP connections for local or remote system

.FUNCTIONALITY
    Computers

.DESCRIPTION
    Display current TCP/IP connections for local or remote system.  Includes the process ID (PID) and process name for each connection.
    If the port is not yet established, the port number is shown as an asterisk (*).    

.PARAMETER ProcessName
    Gets connections by the name of the process. The default value is '*'.

.PARAMETER Port
    The port number of the local computer or remote computer. The default value is '*'.

.PARAMETER Address
    Gets connections by the IP address of the connection, local or remote. Wildcard is supported. The default value is '*'.

.PARAMETER Protocol
    The name of the protocol (TCP or UDP). The default value is '*' (all)

.PARAMETER State
    Indicates the state of a TCP connection. The possible states are as follows:

    Closed      - The TCP connection is closed. 
    Close_Wait  - The local endpoint of the TCP connection is waiting for a connection termination request from the local user. 
    Closing     - The local endpoint of the TCP connection is waiting for an acknowledgement of the connection termination request sent previously. 
    Delete_Tcb  - The transmission control buffer (TCB) for the TCP connection is being deleted. 
    Established     - The TCP handshake is complete. The connection has been established and data can be sent. 
    Fin_Wait_1  - The local endpoint of the TCP connection is waiting for a connection termination request from the remote endpoint or for an acknowledgement of the connection termination request sent previously. 
    Fin_Wait_2  - The local endpoint of the TCP connection is waiting for a connection termination request from the remote endpoint. 
    Last_Ack    - The local endpoint of the TCP connection is waiting for the final acknowledgement of the connection termination request sent previously. 
    Listen      - The local endpoint of the TCP connection is listening for a connection request from any remote endpoint. 
    Syn_Received    - The local endpoint of the TCP connection has sent and received a connection request and is waiting for an acknowledgment. 
    Syn_Sent    - The local endpoint of the TCP connection has sent the remote endpoint a segment header with the synchronize (SYN) control bit set and is waiting for a matching connection request. 
    Time_Wait   - The local endpoint of the TCP connection is waiting for enough time to pass to ensure that the remote endpoint received the acknowledgement of its connection termination request. 
    Unknown     - The TCP connection state is unknown.

    Values are based on the TcpState Enumeration:

    Cookie Monster - modified these to match netstat output per here:
    http://support.microsoft.com/kb/137984

.PARAMETER ComputerName
    If defined, run this command on a remote system via WMI.  \\computername\c$\netstat.txt is created on that system and the results returned here

.PARAMETER ShowHostNames
    If specified, will attempt to resolve local and remote addresses.

.PARAMETER tempFile
    Temporary file to store results on remote system.  Must be relative to remote system (not a file share).  Default is "C:\netstat.txt"

.EXAMPLE
    Get-NetworkStatistics | Format-Table

.EXAMPLE
    Get-NetworkStatistics iexplore -computername k-it-thin-02 -ShowHostNames | Format-Table

.EXAMPLE
    Get-NetworkStatistics -ProcessName md* -Protocol tcp

.EXAMPLE
    Get-NetworkStatistics -Address 192* -State LISTENING

.EXAMPLE
    Get-NetworkStatistics -State LISTENING -Protocol tcp

.OUTPUTS

Answer 1

Dito就像@Kayasax所說的那樣風景如畫-如果沒有powershell， 則不能運行powershell腳本。 命令的替代方法是以下命令，執行並退出：

@powershell C:\Get-NetworkStatistics.ps1

Answer 2

針對您的評論，“ ...我的主要目的是運行此功能Get-NetworkStatistics -computername Gbi1 | Format-Table -autosize ...”

您可以將這兩行添加到Get-NetworkStatistics.ps1的末尾（這是達到目標的一種技巧，使Shay腳本的大部分功能無效）：

$ARG_COMPNAME = $args[0]
Get-NetworkStatistics -computername $ARG_COMPNAME | Format-Table -autosize

然后，按照以下方式調用Powershell腳本：

C:\>powershell.exe -noprofile -file Get-NetworkStatistics.ps1 Gbi1

該腳本運行並轉儲netstat表以進行篩選並轉儲文件c：\\ netstat.txt
