Autojump is a tool that can be used to jump around in the shell to frequently used directories by typing just a part of their name. It is typically aliased to j. Autojump is available as a package in the Ubuntu repositories, but it needs manual intervention to be available in the fish shell.

1. Install autojump

sudo apt install autojump

2. Source the autojump.fish file in your fish configuration, by opening the file ~/.config/fish/config.fish in an editor and adding these lines:

begin
    set --local AUTOJUMP_PATH /usr/share/autojump/autojump.fish
    if test -e $AUTOJUMP_PATH
        source $AUTOJUMP_PATH
    end
end

3. Add j shortcut command to fish creating a new file ~/.config/fish/functions/j.fishwith the following content:

function j
    set new_path (autojump $argv)

    if test -d "$new_path"
        echo $new_path
        cd "$new_path"
    else
        echo "autojump: directory '$argv' not found"
        echo "Try \`autojump --help\` for more information."
        false
    end
end

Usage examples:

– j Down – changes to my Downloads folder
– j work – changes to my workspace folder

Enjoy!

Issue the following commands in the terminal, one by one and you are ready to go! It’s simple as that 🙂

#docker setup
echo "deb [arch=amd64] https://download.docker.com/linux/ubuntu focal stable" | sudo tee /etc/apt/sources.list.d/docker.list
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo apt update
sudo apt install docker-ce docker-ce-cli containerd.io pigz

#execution permission
sudo usermod -aG docker $USER

#docker compose
sudo curl -L "https://github.com/docker/compose/releases/download/2.2.3/docker-compose-$(uname -s | tr '[:upper:]' '[:lower:]')-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose</pre>

First, we need to checkout the following repo containing the driver:

git clone https://git.launchpad.net/~oem-solutions-engineers/libfprint-2-tod1-broadcom/+git/libfprint-2-tod1-broadcom/

Then go into the cloned folder and issue the following commands:

sudo sh install.sh
python3 debian/update-fw.py

You may need to restart the laptop in order the changes to be applied.

Finally, enable fingerprint login using the following command:

sudo pam-auth-update
