Solved File Management removing unprintable characters

[DustinB3403]

@Obsolesce That is absolutely the perfect answer.

@Pete-S said in File Management removing unprintable characters:

If the backup system can't handle all allowed characters in a filename, then that is the problem that needs to be fixed.

While I would generally agree, I have no way to control the file system in my backup location, which complains about the files and just skips them.

So while I agree, use a better back tool that isn't the answer I'm looking for.

@Obsolesce this is great, thank you!

A few things to think about:

• Expect some support calls when you rename customer files and they can't open them using "recent files".
• Also expect problems when you rename a file that someone has open. Normally you can't => script fail.
• Also expect problem if someone makes a new file with the original name. Now there will be two files that will have the same name after the renaming process => script fail.
• Also hope that there aren't any application files that will not pass the regex => application fail.

Is the backup something homemade or something very old perhaps?

I suggest spending some time finding out exactly what characters are supported and making sure the regex is exactly that and not anymore restrictive than needed.
Then make sure the renaming script can handle errors mentioned above.
And I suggest some log file or email sent with files that can't be renamed so you know.

Not my concern in the least

Only targeting files that are marked for "archive" - so not an issue

We already punch people in the back of the head for this

Nope

Using B2 CLI to move stuff, so not old at all.

This really sounds like an HR problem that you're kinda solving with tech. If it's not against company policy to use those characters in file names/paths - then what you wanting to do is likely the wrong approach... and instead management should be approving you to find a new backup solution that works with those filenames.

There is no policy on this, not would there be one.

This is an insane way to think about that.

Okay so with a bit more offline assistance from @Obsolesce

This is what works

(Get-ChildItem -Path "some\path" -Recurse | Rename-Item -NewName {$_.Name -replace '•','-'} -verbose)

Obviously it's only hitting on that bullet point, and replacing it with a hyphen, but that's better than the operation failing over and over and not ever knowing it.

If you want to know if there's an error, you can build that in like this:

(Get-ChildItem -Path "C:\test" -Recurse | Rename-Item -NewName {$_.Name -replace '[^\p{L}\p{Nd}\p{P}]','-'} -WhatIf -ErrorAction SilentlyContinue -ErrorVariable daError)
if ($daError) {
    Write-Output "ERROR - There was an error. Pay attention : [$daError]"
}

See, you wanting to change the way users work to suit IT is generally something @scottalanmiller would say is likely wrong for the business.

You have to realize that there are multi-national companies everywhere. So when you have problems with filenames, it's extremely unlikely that something modern will not support whatever it is you are doing - as long as the filename is valid on the OS you are using. And Backblaze of course supports all characters.

https://www.backblaze.com/b2/docs/string_encoding.html

Maybe there is a bug somewhere or maybe you are using it the wrong way. But this is the actual problem, not that users use whatever filename they want.

Well, let's back up. Why are people using those characters? Chances are they are real characters. They are getting in there somehow, and not likely from someone trying to be weird, but likely from an alternative keyboard or something.

[DustinB3403]

@Pete-S Using a bullet point in a damn folder or file name is not at all normal!

FFS.

If you think a file or folder named

• some crap

Is used globally, you're just wrong.

The reasoning as far as I've seen is it puts the content at the top of the list as the main culprit excuse. One which I'd rather not try to "fix" since it's well beyond my ability to hit these fools hard enough.

[scottalanmiller]

But a bullet point is printable and I bet some languages use it somewhere. But maybe it came from some odd cut and paste procedure. But something is causing this to happen, I assume that this isn't all one person?

Well that definitely isn't a good reason if they are trying to use special characters as indexing data.

Our staff are pulled onto so many projects that I wouldn't even have an idea of who or when something like a copy and paste issue occurred.

Is it possible, absolutely.

Is it also happening far too often, absolutely and thus I'll fix it when the files are closed via powershell.

@Obsolesce thanks for assisting with this.

It's not printable to B2 and causes failures.

Hence the point in finding a way to find and replace all bullet points in files and folders.

just not with non-traditional characters.

Usually underscores or exclamation marks right?

I had no idea punctuation would be before characters, so no.. I normally do aaa or 111 or some stupid shit.
