python - Determine if Powershell script started in main scope? -


i beginner powershell user. writing script files (.ps1)

i determine how script invoked:

was "main" script or dot sourced file?

in python, use like:

if __name__ == "__main__":

is there similar in powershell?

update

after reading answers, using following @ end of .ps1 file:

if ($myinvocation.invocationname -ne '.') {   # "main" stuff here }

any answers include how fail welcome.

it appears duplicate question, didn't use right search terms: determine if powershell script has been dot-sourced

if you're wanting know how invoked, have @ $myinvocation automatic variable.

if want test if you're in global scope:

try {if (get-variable args -scope 1){$true}} catch {$false}

should return $true if you're running in child scope. if you're in global scope, there no parent scope , throw error , return $false.

i've adapted css use in website , can't quite figure out why 1 aspect of page acting way acting. basically, when shrink window below size horizontally, of text "drops down". becomes issue if user viewing website through ipad vertical orientation. can view issue here . i'm hoping make if window gets smaller, placement of text remains intact. the problem area not have enough space put both side navigation , content on 1 line. make automatically adjust page's width when exceeds decrements of width. this code example, , highly unlikely work. if see css more clearly, provide exact code. @media , (max-width:960px) { /* assuming #wrapper 960px across */ #content {width:560px;} /* opposed 720px */ } edit the content drops down @ 980px, have shrink width after there. @media , (max-width:980px) { #container {width:520px;} }
