`$PSScriptRoot` unpopulated when script missing the `.ps1` file extension about powershell HOT 10 CLOSED

Is this a duplicate of #21402 ?

from powershell.

#!/bin/sh -e

It's more bourne itself, I don't want to have to look up the intricacies of $@ et cetera and any caveats involved with explicitly using pwsh's -File, even if it turns out there are none for either. It's much simpler to just rename the script for now.

Looks like it.

They need to update the title with the real cause of the issue; the calling name ($args[0] in other languages, eg $0 in bash) is missing the .ps1 is the cause.
Seems it's not so much the name of the actual script itself.
Keeping it "Symbolic links can change..." is impossible to search if you're closer to the real problem à la "...script missing .ps1 extension".

To add; I think what's really responsible is that $MyInvocation has .MyCommand listed as the whole script as a raw string, instead of the script as a file, when the extension is missing.
If MyCommand isn't a file it cannot have a path.

Can't dupe a closed-due-to-inactivity issue.

#21402 did have a work around, creating a shell script without the extension adjacent to the powershell script with ps1

#!/bin/sh -e
exec pwsh -File "$0.ps1" "$@"

I've just resorted to keeping the .ps1 on the actual script instead of pushing args and input&output streams through an intermediary, and hopefully this'll get fixed one day.
It took forever for something huge like 1908 to get done, but it did get done!

Just so you know, the exec means no fork occurs and pwsh replaces sh with the same process id, environment, file descriptors etc. There is no intermediate.

This issue has been marked as duplicate and has not had any activity for 1 day. It has been closed for housekeeping purposes.
