确定 PowerShell 脚本是否已点源 [英] Determine if PowerShell script has been dot-sourced

问题描述

从 PowerShell 脚本中，我如何确定脚本是否是点源的，即它已被调用

<预><代码>..\myscript.ps1

而不是

.\myscript.ps1

注意一个有趣的博客文章(也)关于这个:http://poshoholic.com/2008/03/18/powershell-deep-dive-using-myinvocation-and-invoke-expression-to-support-dot-sourcing-and-direct-invocation-in-shared-powershell-scripts/

解决方案

检查 $myinvocation.line它将显示用于调用脚本的行.

 PS C:\scripts\test>GC测试.ps1$myinvocation.linePS C:\scripts\test>./test.ps1./test.ps1PS C:\scripts\test>../test.ps1../test.ps1

您还可以检查 .invocationname 属性.如果脚本是点源的，它将只是一个点.如果不是，则是 ./scriptname.ps1

From a PowerShell script, how can I determine if the script has been dot-sourced, i.e. it has been called with

. .\myscript.ps1

rather than

.\myscript.ps1

NOTE an interesting blog post (also) about this: http://poshoholic.com/2008/03/18/powershell-deep-dive-using-myinvocation-and-invoke-expression-to-support-dot-sourcing-and-direct-invocation-in-shared-powershell-scripts/

解决方案

Check $myinvocation.line It will show the line that was used to call the script.

 PS C:\scripts\test> gc test.ps1
 $myinvocation.line

 PS C:\scripts\test> ./test.ps1
 ./test.ps1

 PS C:\scripts\test> . ./test.ps1
 . ./test.ps1

You can also check the .invocationname property. If the script was dot-sourced, it will just be a dot. If not, is will be ./scriptname.ps1
