✅ Does `FileSystemWatcher` work on linux? (Trying to monitor for files being added or renamed)

Hi. Im trying to monitor a directory for any files being added to it or renamed. I found FileSystemWatcher but the platform support is unclear. I suspect it does not work on linux because many of the events don't make sense on linux (e.g. how would LastWrite work when files arent locked on linux)

Does this work on linux? if not what should I use instead?

The docs don't mention anything about it not working on Linux for what it's worth

It works

just didnt want to write a bunch of code to handle the file and have it work on my windows laptop, only to deploy it to my server and find out it doesnt actually work lol

3333fred It works

GNUGradynOP•1/6/23, 9:45 PM

just works? does it just not fire LastWrite then?

333fred•1/6/23, 9:45 PM

Though many linux systems have a lower number of inotify instances

333fred•1/6/23, 9:47 PM

What do you think LastWriteLastWrite means?

GNUGradynOP•1/6/23, 9:48 PM

I assumed it fired when the file was unlocked

333fred•1/6/23, 9:48 PM

It fires when the last written time changes

333fred•1/6/23, 9:48 PM

When that happens is OS-dependent

GNUGradynOP•1/6/23, 9:48 PM

ohhhhh

GNUGradynOP•1/6/23, 9:49 PM

an article i was reading suggesting watching for LastWrite to avoid picking up files that arent done being written to yet

333fred•1/6/23, 9:49 PM

It doesn't mean "the last write has occurred", if that's what you were thinking

333fred•1/6/23, 9:49 PM

I mean, that might certainly work

GNUGradynOP•1/6/23, 9:49 PM

yeah, the article suggested using it as such so i assumed it meant "the last write has occured"

GNUGradynOP•1/6/23, 9:50 PM

maybe ill just handle this firefox style and add .part.part to files until they're done being written and it can just ignore any .part.part files

333fred•1/6/23, 9:50 PM

But more because that's when the OS considers the file content to have been flushed to disk

333fred•1/6/23, 9:50 PM

Both firefox and chrome do that

GNUGradynOP•1/6/23, 9:50 PM

then I don't have to worry about nuances in when the OS considers it "done" and such

333fred•1/6/23, 9:50 PM

Though chrome uses a different ext

GNUGradynOP•1/6/23, 9:50 PM

ah interesting, i dont use chrome much lol

GNUGradynOP•1/6/23, 9:50 PM

thank you

GNUGradynOP•1/6/23, 9:50 PM

this was very helpful i appreciate it
