在其他脚本中使用变量/从脚本中提取变量

Question

I have multiple Variables in my first Script

$var1= Moon
$var2= Sun
$var3= Earth

Some lines with var1, var2, var3...

...

...

---

In a few other scripts I have lines which need those variables but I do not want to define them in those scripts, only in the first one.

EDIT: Basically I am trying to pull variables from anther script, while only running the pulling script.

Write-Host"$var1"
Write-Output"$var2"

...

...

I've found a few answers online, but those did not really help me... hope someone here can:D

Well to start you can "dotsource(. C:\test\test.ps1)" the first script from the second one meaning that all the variables will be loaded with it.

You can also pass arguments between files:

# file1.ps1

$var1= Moon
$var2= Sun
$var3= Earth

C:test\test.ps1 $var1 $var2 $var3

############################################################

# file2.ps1

write-output $args[0] # moon
write-output $args[1] # sun
write-output $args[2] # earth

Another option is to write them to a file and pull them out in the new script (xml, json, csv, etc.) Or you make a file3.ps1 wich calls both the scripts while passing variables to them.

EDIT: After some testing i found that if you call the second file from the first the variable can just be used. Your sample code will work.

# File1.ps1
$var1= "Moon"
$var2= "Sun"
$var3= "Earth"

C:\test\test.ps1

# test.ps1
write-host $var1
write-output $var2
write-warning $var3

Your original code would have worked outside of the syntax errors.
