如何使用参数从cmd.exe运行内部Powershell脚本函数

Question

I want to use a powershell (.ps1) script in the command prompt without using this commands

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

Currently this command opens powershell windows. I want direct cmd to use this script and giving me output. Is it possible?

Below is my Get-NetworkStatistics.ps1 script. please guide me is there any way to use it directly?

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:

.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 to what @Kayasax said so picturesquely - you cannot run a powershell script without powershell, period. An alternative to your command is the following, executes and exits:

@powershell C:\Get-NetworkStatistics.ps1

Answer 2

In response to your comment, "...my main purpose it to run this function Get-NetworkStatistics -computername Gbi1 | Format-Table -autosize ..."

You can add these two lines to the end of Get-NetworkStatistics.ps1 (This is a hack to get your purpose met, negates most of the power of Shay's script):

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

Then you call the Powershell script along the lines of:

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

The script runs and dumps a netstat table to screen and dumps a file c:\\netstat.txt
