Powershell script changes directory of parent powershell - powershell

Question

When running a powershell script which changes a directory via cd (or set-location/push-location/etc.), the console that the script was run from also ends up in that directory.
Example:
script.ps1
cd c:\tmp
# do stuff
If I run this from c:\users\me, i end up in c:\tmp.
PS C:\users\me> .\script.ps1
PS C:\tmp> |
Now I know that I could use push-location and later do pop-location. However this wouldn't work if the script stopped somewhere in the middle (via Exit).
How can I solve this? Why doesn't the script have it's own location stack?

Answer 1

You could always use Try/Catch/Finally. Set the current directory path to a variable and then cd c:\tmp before the Try, and have the directory changed to variable in the Finally?
Example 1
$path = (Get-Item -Path ".\" -Verbose).FullName
cd c:\temp
Try
{
#Do stuff
#exit is fine to use
#this will output the directory it is in, just to show you it works
Write-Host (Get-Item -Path ".\" -Verbose).FullName
}
Catch [system.exception]
{
#error logging
}
Finally
{
cd $path
}
Example 2 using popd and pushd
pushd c:\temp
Try
{
#Do stuff
#exit is fine to use
#this will output the directory it is in, just to show you it works
Write-Host (Get-Item -Path ".\" -Verbose).FullName
}
Catch [system.exception]
{
#error logging
}
Finally
{
popd
}
I'd also recommend looking at what arco444 suggested, which is calling the powershell script via the -File parameter. Depending on the scenario that might work as an option.
