Shell Startup File

env.sh

• The env.sh is a config file to seperate aliases, exports, path, etc from the shell startup files.
• It is aim to not pollute the ~/.bashrc or ~/.zshrc too much.
• Create $HOME/env.sh using your favorite text editor:

# Java
export JAVA_HOME="`/usr/libexec/java_home -v 1.8`"

# Node Version Manager
export NVM_DIR="$HOME/.nvm"
. "/usr/local/opt/nvm/nvm.sh"
nvm use 6.9.2

# Ruby rbenv
if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi

# For long shell history
if [[ $SHELL == '/usr/local/bin/zsh' ]]; then
    HIST_STAMPS="yyyy-mm-dd"
    HISTSIZE=2147483647
    SAVEHIST=2147483647
    alias history='fc -il 1'
else
    export PROMPT_COMMAND='history -a'
    export HISTTIMEFORMAT="%Y-%m-%d %T "
    export HISTFILESIZE=2147483647
    export HISTSIZE=2147483647
fi

# For Google Cloud SDK
if [[ $SHELL == '/usr/local/bin/zsh' ]]; then
    # The next line updates PATH for the Google Cloud SDK.
    if [ -f $HOME/google-cloud-sdk/path.zsh.inc ]; then
      source $HOME/google-cloud-sdk/path.zsh.inc
    fi

    # The next line enables shell command completion for gcloud.
    if [ -f $HOME/google-cloud-sdk/completion.zsh.inc ]; then
      source $HOME/google-cloud-sdk/completion.zsh.inc
    fi
else
    # The next line updates PATH for the Google Cloud SDK.
    if [ -f $HOME/google-cloud-sdk/path.bash.inc ]; then
      source $HOME/google-cloud-sdk/path.bash.inc
    fi

    # The next line enables shell command completion for gcloud.
    if [ -f $HOME/google-cloud-sdk/completion.bash.inc ]; then
      source $HOME/google-cloud-sdk/completion.bash.inc
    fi
fi

• Note: For JAVA_HOME, change the version based on your Java version.

• Note: For Node Version Manager, change the version based on your Node.js version that you use most of the time.

• Then edit your ~/.bashrc and ~/.zshrc (if you are using Zsh) and appened the followings:

  if [ -f $HOME/env.sh ]; then
        source $HOME/env.sh
  fi
  

Bash Startup files

• If you are using the default Bash Shell, create ~/.bash_profile if it does not exist.

• Then edit your ~/.bash_profile and append the followings:

  if [ -f $HOME/.bashrc ]; then
        source $HOME/.bashrc
  fi
  

• To check, open a new terminal tab by pressing keys Cmd+T, then type:

  echo $PATH
  

• You should able to see the output like this:

  /Users/sierra/.rbenv/shims:/Users/sierra/.nvm/versions/node/v6.9.2/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
  

• If you see the output like this instead:

  /usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
  

• Either env.sh or .bashrc is not loaded properly.
