Shell Configurations

1. SSH Key

You will need a public SSH key to authenticate with services like GitHub.

  1. Create a new SSH key:

    ssh-keygen -t ed25519 -C "admin@localhost.com"

  2. Adjust your ~/.ssh/config file.

    ###########
#  ~/.ssh/config
###########

Host *
  AddKeysToAgent yes
  UseKeychain yes

Host github.com
  HostName github.com
  PreferredAuthentications publickey
  IdentityFile ~/.ssh/github-id_ed25519

  3. Copy your new public SSH key (~/.ssh/*.pub)

  4. Add it to your Git account as an authentication key and a signing key.

2. XCode

If you're developing on macOS, you'll need XCode command-line tools.

  1. Run the command to install:

    xcode-select --install

  2. Follow the on-screen instructions to complete the installation.

  3. After installation, verify the tools (e.g., git, svn, make) are available in: /Library/Developer/CommandLineTools/usr/bin/.

3. Bash

For a better terminal experience, customize it to fit your workflow.

  1. Check your current shell:

    echo $SHELL

  2. If you want to switch to bash, run the following command:

    chsh -s /bin/bash

  3. Set up configuration symlinks:

    # Common login configuration
ln -sf ~/geojuji/shell/bash/bash_profile  ~/.bash_profile
# Contains some needed aliases
ln -sf ~/geojuji/shell/bash/bash_aliases  ~/.bash_aliases

📝 In the bash_profile file, a reference to the ~/geojuji/shell/bash/bin/ folder has been added to the $PATH for executable files. You can add new binaries to that folder but make sure all scripts added have their permissions set to executable (e.g., chmod 755).

4. Git

Configure git for version control.

  1. Rename and update your personal Git configuration file:

    mv ~/geojuji/shell/git/gituser.example ~/geojuji/shell/git/gituser

    Update name, username, and email fields.

  2. Symlink git configuration files:

    # Your personal configuration
ln -sf ~/geojuji/shell/git/gituser     ~/.gituser
# The common configuration
ln -sf ~/geojuji/shell/git/gitconfig   ~/.gitconfig
# List global files to be ignored
ln -sf ~/geojuji/shell/git/gitignore   ~/.gitignore
# All needed aliases
ln -sf ~/geojuji/shell/git/gitaliases  ~/.gitaliases

📝 For installing some git autocompletion, run:

curl https://raw.githubusercontent.com/git/git/master/contrib/completion/git-completion.bash -o ~/.git-completion.bash
