關於windows powershell的想法

前段日子安裝了SQL2008CTP,並意外發現了一個工具,叫做"Windows PowerShell 1.0",好奇心的驅使,我打開了這個工具,既爲POWER,是不是也支持LINUX下的SHELL命令呢?

LS/MAN/RM/CP等居然都支持,也支持MAN,雖然在實現在不同,但我想至少是在向UNIX邁步了,但是一旦MAN LS後,得到的幫助內容是如下的:

NAME
    Get-ChildItem

SYNOPSIS
    Gets the items and child items in one or more specified locations.

SYNTAX
    Get-ChildItem [[-path] <string[]>] [[-filter] <string>] [-include <string[]>] [-exclude <string[]>] [-name] [-recur
    se] [-force] [<CommonParameters>]

    Get-ChildItem [-literalPath] <string[]> [[-filter] <string>] [-include <string[]>] [-exclude <string[]>] [-name] [-
    recurse] [-force] [<CommonParameters>]

DETAILED DESCRIPTION
    The Get-Childitem cmdlet gets the items in one or more specified locations. If the item is a container, it gets the
     items inside the container, known as child items. You can use the Recurse parameter to get items in all child cont
    ainers A location can be a file system location, such as a directory, or a location exposed by another provider, su
    ch as a registry hive or a certificate store.

也就是雖然MAN LS了,但是MS卻提供了另一個命令的使用方法,後來看到MS也提供了LINK,是否LS就是一get-childitem的LINK呢,乾脆就直接MAN,可用的命令有很多,挑幾個重要的:

ls                                      Alias                                   Get-ChildItem

history                                 Alias                                   Get-History
kill                                    Alias                                   Stop-Process
lp                                      Alias                                   Out-Printer
ls                                      Alias                                   Get-ChildItem
mount                                   Alias                                   New-PSDrive
mv                                      Alias                                   Move-Item
popd                                    Alias                                   Pop-Location
ps                                      Alias                                   Get-Process
pushd                                   Alias                                   Push-Location
pwd                                     Alias                                   Get-Location

等等命令只是一個ALIAS,MS你做個SHELL也罷了,爲什麼了提供ALIAS指向UNIX命令?

另外在"USER GUIDE"看到:

 

Windows PowerShell was designed to take advantage of a user's historic knowledge of CLIs. In this chapter, we will talk about some basic tools and concepts that you can use to learn Windows PowerShell quickly. They include:

·      Using Get-Command

·      Using Cmd.exe and UNIX commands

·      Using External Commands

·      Using Tab-Completion

·      Using Get-Help
