I think it's good practice to always use long arguments in (bash) scripts, for the same reason that a variable named `userLastName` is better than one named `str2`.

Because you mentioned it, PowerShell has a similar readability issue with positional parameters `Set-Content $file $text` vs `Set-Content -Path $file -Value $text`. In many cases the use and order is obvious, but it's not always (and will vary by person), and inconsistent style in code also makes it harder to read.

There's no silver bullet for this stuff. You have to be aware of context and future maintainers: If the vast majority of your code is bash and all maintainers are highly skilled in it, go nuts. If most of your product is in another language and you just have some ancillary install or build scripts in bash/PowerShell/whatever, you should assume people looking at it are closer to the beginner level, and it's better to make things as readable as possible.
