comment Why does this line appear every time I launch iTerm on my MacBook?
The string might not be included in the script that way - it's quite possible that it's created dynamically from your home directory (something like echo . $HOME/Dropbox/private/autosync").

comment How long can file system writes be cached with ext4?
I'm pretty sure he meant the former, the latter would make ext4 on Linux a pretty dangerous file system to use ;) The script looks like a nice workaround; I'll give it a try and maybe evaluate some of my most important applications with strace - maybe they are all using fsync(), and I'm worrying too much...

comment How long can file system writes be cached with ext4?
Really? In bugs.launchpad.net/ubuntu/+source/linux/+bug/317781/comments/45 it is specifically mentioned that unallocated pages will NOT be written to disk on a commit (but of course on an fsync()). The patch fixes some common cases where that behavior is problematic by forcing allocation; however, there is nothing said about overwriting data.

Thanks, the "ALL dirty data" part was exactly what I was worrying about! I was worried that there were more exceptions in addition to delayed allocation (which can cause new data to remain in the write cache even after the commit interval).

I know about fsync(); I'm asking as a user of applications that might or might not use it. I've updated my question.

comment (How) does deleting open files on Linux and a FAT file system work?
@Scott, yes, that is exactly what I meant. It seems that Linux actually does that, because when I uncleanly unmount a FAT file system with opened but deleted files on it, there is always some corruption detected by fsck.vfat, and it always is about blocks not marked as free but also not part of any file - which would suggest that the directory entry is deleted, but the corresponding blocks in the FAT are not set to show up as free space until the last handle is closed.
