PSMDTAG:FAQ: How can a script determine what directory it was invoked from?
PSMDTAG:FAQ: What is $MyInvocation?
PSMDTAG:FAQ: Why is $MyInvocation.ScriptName empty?<\/p>\n
Create 2 scripts (First.PS1 and Second.PS1) to explore what is going on with $MyInvocation and how you can use it to determine what directory a script was invoked from:<\/p>\n
PS> cat first.ps1 PS> cat second.ps1 PS> .\\first.ps1 <\/font> <\/p>\n ***** Second MYINVOCATION *****<\/font> <\/font> <\/p>\n ***** Second MYINVOCATION.MyCommand *****<\/font> PS><\/font><\/p>\n When you run First.ps1, you see that ScriptName is empty. The reason for this is that ScriptName refers to the name of the script that called you (Yes – we probably should have chosen a better name). Notice that when First.Ps1 calls Second.Ps1, ScriptName is the path to First.PS1.<\/font><\/p>\n Now look at $MyInvocation.MyCommand. The PATH property tells you the full path of the current script. If you want the directory you do the following:<\/font><\/p>\n $myDir = Split-Path -Parent $MyInvocation.MyCommand.Path<\/strong> Jeffrey Snover [MSFT] <\/p>\n PSMDTAG:CMDLET:UTILITY: Split-Path<\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" PSMDTAG:FAQ: How can a script determine what directory it was invoked from?PSMDTAG:FAQ: What is $MyInvocation?PSMDTAG:FAQ: Why is $MyInvocation.ScriptName empty?
