sed temp file appears in nautilus but not in ls -a

[Junior Martins]

**Expected behaviour**:
Temp files created by sed should disappear from Nautilus after automatic deletion

**Observed behaviour**:
Temp files showed in Nautilus for some time.

**Description**:

After using:
sed -i 's/CAD/cad/g' FILENAME

The temp files created by sed (sed#####) continued showing in Nautilus for some minutes (they disappear if I close and reopen Nautilus), and I could interact with them (see permissions, double click to open (which errored out by not finding an app to open it), but couldn't change them (move, change permissions, delete)

These temp files did not appear with ls -a.

The file is 3.6kb long.

The behaviour doesn't happen with: sed -i 's/cad/CAD/g' FILENAME but only with: sed -i 's/CAD/cad/g' FILENAME

**Outputs**:

Thank you for your bug report, could you share the output of

$ gio monitor <dir> (where <dir> is the path to the directory where you are doing the change)

which filesystem are you using?

[Junior Martins (jrom)]

I used "gio monitor ." at the directory. I don't know what my filesystem is, but in AskUbuntu it was mentioned that I could use "df -T", I hope this helps.

DIRNAME is the absolute path of the directory (I can't show it, it has upper and lowercase characters and also spaces, it that's relevant), and it seemed to get worse, since now both
sedFJdiNs and sedoH8a25 showed in Nautilus. They disappeared when I pressed F5 about a minute later.

After sed -i 's/CAD/cad/g' dados_snps_AMR.tsv

[Sebastien Bacher (seb128)]

The gio monitor seems to correctly notice the change, weird. There are some similar issues which had been reported upstream, for example https://gitlab.gnome.org/GNOME/nautilus/-/issues/288 but never without enough information to be debugged and resolved

I'm using GNOME 3.38.4 and I just tried mv, touch, mkdir, rmdir and cp, and Nautilus updated instantly.
