Sometimes Nautilus’ icon thumbnails and metadata just isn’t good enough. Sometimes you want to take a closer look at a file, photo or folder to make sure it’s the one you want — but without opening a full-blown app.
And that’s where GNOME’s Sushi can help.
Sushi is a macOS style ‘Quick Look‘ feature for GNOME’s famous file manager. You select a file then tap the spacebar to see an instant close-up (and sometimes interactive) preview of the file, without opening any app.
Previewing music and video files is made possible due to the GStreamer framework. But Sushi also supports file previews of most plaintext documents too, including scripts with syntax highlighting, PDFs and HTML files.
And, yes, it’s great for gawking through photos too:
Sadly Sushi doesn’t update the preview window if you ‘move’ off and select a different file; you have to explicitly close the window or hit
space again. This lack of intuitive behaviour spoils the tool (it’s something macOS version does excellently) but here’s hoping devs add it in!
Another feature Sushi lacks from its macOS counterpart are ‘actions’. You can’t, for instance, use Sushi to find the right image and then tap a button in the preview to open it in your preferred image viewer or photo editor. You have to close Sushi and open the file manually.
Install GNOME Sushi on Ubuntu
Although a modest feature (there are no bells or whistle or even preferences) Sushi’s seamless preview prowess is such that, after a few days use, you’ll wonder how you managed without it.
To install Sushi on Ubuntu 18.04 LTS or above run the command:
sudo apt-get install gnome-sushi
Alternatively, install the app using Ubuntu Software:
As soon as you install GNOME Sushi it is instantly available to use. Just open Nautilus, select a file using your mouse or keyboard arrow keys, and hit the
spacebar to preview it!
In short, GNOME Sushi gives you a quick and effective way to take an instantaneous look at PDF files, photos, and other documents without needing to open them fully. I consider it a definite must have on my desktop — let me know what you think in the comments!
