• xcwd https://github.com/schischi/xcwd A simple tool that prints the current working directory of the currently focused window

Notes on the flags, learned the hard way:

• -f makes these idempotent. Without it, every line fails with File exists on a machine that already has the file — i.e. on every fresh install.
• -n matters for the two directory links (ftplugin, polybar). Without it ln -sf puts the link inside an existing target dir (~/.vim/ftplugin/ftplugin) instead of replacing it.
• No sudo for links under $HOME — it only creates root-owned symlinks in your own home and makes them awkward to edit later. sudo is needed only for the two /etc paths at the bottom.

Create parent directories first (but not ~/.config/polybar, which is itself a link target):

mkdir -p ~/.config/nvim ~/.config/i3 ~/.config/yamllint ~/.vim ~/.local/share/applications

ln -sfn $HOME/Workspaces/rc/.bashrc  ~/.bashrc
ln -sfn $HOME/Workspaces/rc/.vimrc  ~/.vimrc
ln -sfn $HOME/Workspaces/rc/nvim/init.lua ~/.config/nvim/init.lua
ln -sfn $HOME/Workspaces/rc/.gitconfig  ~/.gitconfig
ln -sfn $HOME/Workspaces/rc/.gitignore_global  ~/.gitignore_global
ln -sfn $HOME/Workspaces/rc/i3config  ~/.config/i3/config
ln -sfn $HOME/Workspaces/rc/.git-completion.bash  ~/.git-completion.bash
ln -sfn $HOME/Workspaces/rc/.fzf.bash  ~/.fzf.bash
ln -sfn $HOME/Workspaces/rc/ftplugin  ~/.vim/ftplugin
ln -sfn $HOME/Workspaces/rc/Xresources ~/.Xresources
ln -sfn $HOME/Workspaces/rc/yamllint  ~/.config/yamllint/config
ln -sfn $HOME/Workspaces/rc/nightly.desktop ~/.local/share/applications/nightly.desktop
ln -sfn $HOME/Workspaces/rc/lotion.desktop ~/.local/share/applications/lotion.desktop
ln -sfn $HOME/Workspaces/rc/polybar ~/.config/polybar
ln -sfn $HOME/Workspaces/rc/.psqlrc ~/.psqlrc
ln -sfn $HOME/Workspaces/rc/.alacritty.toml ~/.alacritty.toml
ln -sfn $HOME/Workspaces/rc/starship.toml ~/.config/starship.toml
ln -sfn $HOME/Workspaces/rc/.ideavimrc ~/.ideavimrc
ln -sfn $HOME/Workspaces/rc/profile ~/.profile

These two replace files shipped by Ubuntu, so keep a backup of the original:

sudo cp --no-clobber /etc/default/keyboard /etc/default/keyboard.orig
sudo ln -sfn $HOME/Workspaces/rc/keyboard /etc/default/keyboard
sudo mkdir -p /etc/X11/xorg.conf.d
sudo ln -sfn $HOME/Workspaces/rc/touchpad.conf /etc/X11/xorg.conf.d/touchpad.conf

/etc/default/keyboard sets the US layout and remaps Caps Lock to Ctrl (XKBOPTIONS="ctrl:nocaps"). It only takes effect on login; to apply it to the running session without a reboot:

setxkbmap -layout us,gb -variant altgr-intl, -option "" -option ctrl:nocaps

To list all variants for us layout: localectl list-x11-keymap-variants us

IBus can also sometimes override settings from /etc/default/keyboard. You can use the ibus-setup command to modify the settings for IBus. To force it to defer to the settings from /etc/default/keyboard, run ibus-setup, go to the Advanced tab, and check Use system keyboard layout.

The file pkglist can be re-generated with: sudo dpkg --get-selections | sed "s/.*deinstall//" | sed "s/install$//g" > ~/pkglist

The packages can then be installed with:

sudo aptitude update && cat pkglist | xargs sudo aptitude install -y

Install https://github.com/rjekker/i3-battery-popup/blob/master/i3-battery-popup

1. Create a little script /bin/docker-compose with content docker compose "$@"

2. Make the script executable: sudo chmod +x /bin/docker-compose

3. Check that it works with docker-compose version
