相当于Powershell中的Bash别名 [英] Equivalent to Bash Alias in Powershell

问题描述

一个新手的权力问题：

我想在一个与这个Bash别名完全相同的权力中创建一个别名：

别名django-admin-jy =jython /path/to/jython-dev/dist/bin/django-admin.py

到目前为止，我发现这是非常困难的。

-Powershell别名仅适用于Powershell命令+函数调用

- 没有明确的方式允许在PowerShell函数调用上无限数量的参数

-Powershell似乎阻止stdout

更新：为powerhell中bash别名模拟的工作实现添加了150个奖励。

值得注意的是，我已经尝试了解决方案： http://huddledmasses.org/powershell-power-user-tips-bash-style-alias-command/

并在加载powershell时收到以下与语法有关的错误：

我会接受一个修正，作为一个答案。
解决方案
 PowerShell别名可用于包含EXE的任何命令：
  new-alias n notepad.exe 
  
 更新：as在评论中提到，PowerShell别名不允许参数。它们是命令名称的简单别名，而不再是命令名称。要获得你以后的东西（我认为自从我不熟悉Bash别名）尝试这样：
  function django-admin -jy {
 jython.exe /path/to/jython-dev/dist/bin/django-admin.py @args 
} 
  
它使用PowerShell 2.0的功能，称为参数分割。您可以将 @ 应用于引用数组或散列表的变量名称。在这种情况下，我们将它应用于名为 args 的变量，其中包含所有未命名的参数。 
 
 
 
如果您想要一个真正通用的方法来创建参数的别名函数，请尝试：
 函数New-BashStyleAlias（[string] $ name，[string] $ command）
 {
 $ sb = [scriptblock] :: Create（$ command）
新项目功能：\global：$ name-Value $ sb | Out-Null 
} 
 
新建BashStyleAlias django-admin-jy'jython.exe /path/to/jython-dev/dist/bin/django-admin.py @args'
  
关于Joel的做法，我怀疑他有哪个别名到 Get-Command 。尝试用 Get-Command 替换 。
 
a newbie powershell question:

I'd like to make an alias in powershell exactly equivalent to this Bash alias:

alias django-admin-jy="jython /path/to/jython-dev/dist/bin/django-admin.py"

In tinkering with it so far, I've found this to be very difficult.

-Powershell Aliases only work with Powershell commands + function calls

-No clear way to allow for an unlimited number of args on a powershell function call

-Powershell seems to block stdout



UPDATE: Bounty of 150 pts added for a working implementation of bash alias simulation in powershell.

It's worth noting that I've tried the solution put forth here: http://huddledmasses.org/powershell-power-user-tips-bash-style-alias-command/

And have gotten the following syntax-related error on loading up powershell:



The term 'which' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spell
ing of the name, or if a path was included, verify that the path is correct and try again.
At C:\Users\Dan\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1:9 char:27

+             $cmd = @(which <<<<  $_.Content)[0]
    + CategoryInfo          : ObjectNotFound: (which:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException




I'll accept a fix to this as an answer as well.
解决方案
PowerShell aliases can be used for any "command" including EXEs:
new-alias n notepad.exe
Update: as mentioned in the comments, PowerShell aliases do not allow for arguments.  They are simple "aliases" for a command name and nothing more.  To get what you are after (I think since I'm not familiar with Bash aliases) try this:
function django-admin-jy {
    jython.exe /path/to/jython-dev/dist/bin/django-admin.py @args
}
It uses a feature of PowerShell 2.0 called argument splatting.  You can apply @ to a variable name that references either an array or a hashtable.  In this case, we apply it to the variable named args which contains all the unnamed parameters.  

If you want a truly generic way to create aliases functions that take parameters, try this:
function New-BashStyleAlias([string]$name, [string]$command)
{
    $sb = [scriptblock]::Create($command)
    New-Item "Function:\global:$name" -Value $sb | Out-Null
}

New-BashStyleAlias django-admin-jy 'jython.exe /path/to/jython-dev/dist/bin/django-admin.py @args'
Regarding the issue with Joel's approach, I suspect he has which aliased to Get-Command.  Try replacing which with Get-Command.
