Want to let “Open in Terminal” context (right-click) menu option work for another terminal emulator? Here’s an extension to do the similar job for Nautilus.

When right-clicking on either a folder or blank area in file manager, there’s an “Open in Terminal” menu option to launch system default terminal with that folder as working directory.

The option in Ubuntu so far is provided by the built-in gnome-terminal package. Meaning no way to use the option for another terminal emulator. However, there’s an extension can add similar option to open terminal from in-side folder.

And not only for Gnome Terminal, the extension supports many other terminal emulators:

  • alacritty
  • blackbox
  • cool-retro-term
  • deepin-terminal
  • foot/footclient
  • guake
  • hyper
  • kermit
  • kgx (GNOME Console)
  • kitty
  • konsole
  • mate-terminal
  • mlterm
  • qterminal
  • sakura
  • st properly patched
  • tabby
  • terminator
  • terminology
  • termite
  • tilix (the package itself supports this stuff)
  • urxvt
  • urxvtc
  • wezterm
  • xfce4-terminal

The extension adds the menu option “Open XXX Here“, with XXX changes automatically according which terminal emulator is in use.

How to Install the Nautilus Extension

This tutorial is tested and works in Ubuntu 22.04, Ubuntu 24.04. It should also work in Fedora Workstation and other Linux with GNOME & Nautilus.

1. First, press Ctrl+Alt+T on keyboard to open terminal. Then run command to install git and python3-nautilus package:

sudo apt install python3-nautilus python3-pip gir1.2-gtk-4.0

2. Then, install the extension as pip package, by running command:

pip install nautilus-open-any-terminal --break-system-packages

The --break-system-packages is required for Ubuntu 24.04 due to policy change. Skip it in 22.04

3. Finally, run command to generate the dconf configuration file.

glib-compile-schemas ~/.local/share/glib-2.0/schemas/

Apply and Set your Terminal Emulator

After installed the extension, apply it by running command to quit Nautilus:

nautilus -q

Then, open “Dconf Editor” (install it from Ubuntu Software) and navigate to ‘com/github/stunkymonkey/nautilus-open-any-terminal‘. Finally, set the value of ‘terminal’ to tell which terminal emulator to use.

You can of course choose another terminal emulator by running command (replace kgx with yours terminal app):

gsettings set com.github.stunkymonkey.nautilus-open-any-terminal terminal "kgx"

Tip: You may also remove the built-in ‘Open in Terminal’ option by running command:

sudo apt remove nautilus-extension-gnome-terminal

 

Uninstall

To get rid of the context menu option, simply open terminal (Ctrl+Alt+T) and run command to uninstall the python package:

pip uninstall nautilus-open-any-terminal --break-system-packages

Skip --break-system-packages for Ubuntu 22.04, and run nautilus -q to apply changes.

Got some ePub and/or MOBI books in your PC? Debian / Ubuntu has recently includes a package in their repository for generating thumbnails for these files.

As you may know, Linux Mint 21 was released recently with a thumbnail generators for AppImage, ePub, MP3 and RAW files. Debian/Ubuntu now has similar tool called gnome-epub-thumbnailer, though it’s only for ePub and MOBI books.

With the package installed, the default file manager will no longer display the universal “e” image with green background for all ePub files. Instead, it shows thumbnail book covers.

Don’t know if Ubuntu 22.10 will come with it out-of-the-box, since it’s not released yet. But, user may manually install the package by running the apt command below in terminal.

Open terminal (Ctrl+Alt+T) and run command to install gnome-epub-thumbnailer in Ubuntu 22.10 or Debian Unstable:

sudo apt update && sudo apt install gnome-epub-thumbnailer

NOTE: the package is only for the default GNOME Desktop! Install the Foliate eBook reader from system repository will also install it as recommend dependency package.

Enable EPub / MOBI Thumbnails in Ubuntu 22.04 | 20.04

The package is not available in the current LTS releases. Ubuntu 22.04 user can however download the .deb package directly from the build page:

Click the little triangle for Ubuntu 22.10 (Kinetic Kudu) build to expand, and select download the amd64.deb for modern PC/laptop, arm64/armhf for ARM, or other format depends on your devices.

Finally, double click to open the .deb package via “Software Install” (Ubuntu Software) and install it.

For Ubuntu 20.04 user, I’ve upload the package into this unofficial PPA for 64-bit (amd64) computers support.

To add the PPA and install the package, press Ctrl + Alt +T on keyboard to open terminal and run 3 commands one by one:

sudo add-apt-repository ppa:ubuntuhandbook1/apps
sudo apt update
sudo apt install gnome-epub-thumbnailer

NOTE: The first command will asks for password authentication, though there’s no asterisk feedback. Just type in mind and hit Enter to continue.

Enable EPub / MOBI Thumbnails in Fedora, Arch, SUSE Linux

Most other recent Linux systems have also added the package into their official repositories. If you want to get it, open terminal and run command:

  • For Fedora, use command:
    sudo dnf install gnome-epub-thumbnailer
  • Arch and Manjaro Linux can install it via:
    sudo pacman -S gnome-epub-thumbnailer
  • And, openSUSE user may run command:
    sudo zypper install gnome-epub-thumbnailer

Uninstall the Thumbnails

Thumbnails generate automatically once you installed the package. If somehow you want to get rid of them, open terminal and run command:

sudo apt remove gnome-epub-thumbnailer

Replace apt depends your system. For Arch, use sudo pacman -R gnome-epub-thumbnailer.

Removing the package won’t clear existing thumbnail images, until you removed the content under “~/.cache/thumbnails” either from file manager or by running command:

rm -R ~/.cache/thumbnails/*

Want to embed a terminal in the Files, Nautilus file manager, in Ubuntu? Nautilus Terminal is the project to do the job.

Nautilus Terminal is an open-source project started in 2010. It’s now at version 4.x that supports up to Nautilus 40.

With it, you have an integrated terminal in each file window and tab. The terminal follows the navigation, without running cd command, the terminal automatically go to the directory when you navigate to a folder in file manager.

The terminal placement can be at top (default) or bottom. You can press F4 on keyboard to show or hide it. And it supports drag & drop of file on the terminal.

By right-click on terminal area, you can do copy & paste actions, and go to its Preferences.

The “Preferences” indeed opens Dconf Editor (you need to firstly install it in Ubuntu Software) and navigate to “/org/flozz/nautilus-terminal” settings page. There you can configure:

  • Background color.
  • Text color.
  • Font.
  • Focus by default.
  • Toggle shortcut.
  • Terminal placement.
  • Custom command.

How to Install Nautilus Terminal in Ubuntu 20.04 & Higher:

The project developer used to maintain an Ubuntu PPA, which is however no longer updated. Ubuntu 20.04 and higher users can now run following commands to install it from PyPi.

1.) Open terminal by pressing Ctrl+Alt+T on keyboard. When it opens, firstly run command to install required libraries:

sudo apt install python3-nautilus python3-psutil python3-pip libglib2.0-bin dconf-editor

sudo pip3 install nautilus-terminal

3.) And install it for system wide by running command:

sudo nautilus-terminal --install-system

4.) Finally restart Nautilus to apply changes. To do so, run command:

nautilus -q

NOTE: Ubuntu 18.04 users, can run the previous commands one by one by replacing python3 with python to get integrated terminal in Files.

How to Remove Nautilus Terminal:

To remove the integrated terminal, simply run pip command with uninstall flag in terminal:

sudo pip3 uninstall nautilus-terminal -y

And restart Nautilus via step 4.) to apply changes.

The default size of files and folders in Nautilus file browser does not meet you need? It’s easy to change it in all current Ubuntu releases with Gnome.

Though you can’t find how to configure it either in the System Settings or Gnome Tweaks, Ubuntu do provide an option to set an even larger or smaller icon size, and here’s the quick tip shows you how.

Change File & Folder Size via Single Command:

If you’re familiar with Linux command, you can run a single command to change the size.

Since Nautilus displays files and folders in either icon view or list view, the command can be either:

1.) Change icon size in icon view:

gsettings set org.gnome.nautilus.icon-view default-zoom-level 'large'

Here value ‘large’ can be changed to: ‘small’, ‘standard’, ‘larger’, or ‘largest’.

2.) Change icon size in list view:

gsettings set org.gnome.nautilus.list-view default-zoom-level 'large'

Here value ‘large’ can be changed to: ‘small’, ‘standard’, or ‘larger’.

To reset the change, either run command:

gsettings reset org.gnome.nautilus.icon-view default-zoom-level

or run:

gsettings reset org.gnome.nautilus.list-view default-zoom-level

Change file folder icon size via graphical tool:

Firstly open Ubuntu Software, search for and install dconf editor (or install dconf-editor via apt):

Then launch the tool and navigate to “org/gnome/nautilus/icon-view/default-zoom-level” for the icon size in icon view:

  • Turn off ‘Use default value’
  • Then select a size from ‘Custom value’

For the list view mode, go to “org/gnome/nautilus/list-view/default-zoom-level”.
