Dotfiles

My linux dotfiles and daily used tools, managed with chezmoi. Mainly used on Ubuntu 20.04 Desktop / Server and seldomly used on Ubuntu 20.04 / 22.04 WSL. (The installation scripts for some tools are currently not supported on Ubuntu 18.04.)

Installation

NOTE: These dotfiles and tools are customized according to personal preferences and development needs. Therefore, you are advised to review the code and remove what you don't want or need (especially the scripts in the .chezmoiscripts folder).

Install the chezmoi command and dotfiles from this GitHub dotfile repo on a new machine with this command:

# Option 1: installed by curl
$ sh -c "$(curl -fsLS https://chezmoi.io/get)" -- init --apply qq88976321
# Option 2: installed by wget
$ sh -c "$(wget -qO- https://chezmoi.io/get)" -- init --apply qq88976321

# And then fill in prompts or just leave it empty if you don't need it
# The config file, typically ~/.config/chezmoi/chezmoi.toml, is specific to the local machine.
# [GUI] Does this machine need desktop environment and applications (y/n)?
# [Git] Username?
# [Git] Email address?
# [Git] GnuPG signature key?
# [Git] Private git repository?
