I need to rename only directories and not files, and I want to do it with rename.
Is there any way to do it?
It says nothing in the manual about differentiating between directories and files.
This command changes everything, no matter directory or files:
rename 's/ /\n/g' *
This command solved my problem:
rename 's/ /\n/g' */
I need a slash behind it.

I hate totem player, it is useless to me, so I installed the ffmpegthumbnailer, removed totem player, and changed the default thumbnailer to it by following steps.
sudo apt-get install ffmpeg ffmpegthumbnailer gstreamer0.10-ffmpeg
Then deleted thumbnail cache:
rm ~/.thumbnails/fail/gnome-thumbnail-factory/*
rm ~/.thumbnails/normal/*
I then made a change in /usr/share/thumbnailers/totem.thumbnailer
from this:
[Thumbnailer Entry]
TryExec=/usr/bin/totem-video-thumbnailer
Exec=/usr/bin/totem-video-thumbnailer -s %s %u %o
to this:
[Thumbnailer Entry]
TryExec=ffmpegthumbnailer
Exec=ffmpegthumbnailer -s %s -i %i -o %o -c png -f -t 10
But it can't generate the thumbnails from HEVC Main10P and VP9 codec videos, what should I do?
