原文 2018-01-04 10:44:42 1 1 powershell

Other than Set-Alias being able to change extant aliases, what's the difference between these commands? 除了Set-Alias能够改变现存的别名之外，这些命令之间有什么区别？

Why would someone use New-Alias over Set-Alias ? 为什么有人会使用New-Alias不是Set-Alias ？

1 个解决方案

One (the only one?) advantage in using new-alias is that you will get an error when you override an existing alias. 使用new-alias一个（唯一的？）优势是，当您覆盖现有别名时，您将收到错误。 Otherwise they are synonyms when it comes to alias creation, to quote from help -full new-alias : 否则，在创建别名时，它们是同义词，引用help -full new-alias ：

To create a new alias, use Set-Alias or New-Alias. 要创建新别名，请使用Set-Alias或New-Alias。 To change an alias, use Set-Alias. 要更改别名，请使用Set-Alias。
