Automate the bootstrapping of your new computer
In automating your shell's configuration, you save yourself time each time you get access to a new computer. That is the primary value proposition of automation! No more spending 2-3 hours setting things up. Instead, simply type
./install.sh at the terminal!
The best way I would recommend doing this is by creating a
dotfiles repository. (see: Leverage dotfiles to get your machine configured quickly) Place every file needed for shell initialization inside there -- primarily, I mean the
.bash_profile files, and any other files on which you depend.
Then, create the main script
install.sh, which you execute from within the
dotfiles repository, and have it perform all of the necessary actions to place the right files in the right place. (Or symlink them from the
dotfiles repository to the correct places.)
Configure your machine
After getting access to your development machine, you'll want to configure it and take full control over how it works. Backing the following steps are a core set of ideas:

Leverage dotfiles to get your machine configured quickly
Your dotfiles control the baseline of your computing environment. Creating a dotfiles repository lets you version control it, make a backup of it on a hosted version control site (like Github or Bitbucket) and quickly deploy it to a new system.
It's really up to you, but you want to make sure that you capture all of the
.some_file_extension files stored in your home directory that are also important for your shell runtime environment.
For example, you might want to include your
.zshrc or your
.bashrc files, i.e. the shell initialization scripts.
You might also want to refactor out some pieces from the
.zshrc and put them into separate files that get sourced inside those files. For example, I have two, one for the
PATH environment variable named
.path (see: Take full control of your shell environment variables) and one for aliases named
.aliases (see: Create shell command aliases for your commonly used commands). You can source these files in the
.zshrc file, so I have everything defined in
.aliases available to me.
You can also create an
install.sh script that, when executed at the shell, symlinks all the files from the dotfiles directory into the home directory or copies them. (I usually opt to symlink because I can apply updates more easily.) The
install.sh script can be as simple as:
cp .zshrc $HOME/.zshrc cp .path $HOME/.path cp .aliases $HOME/.aliases
Everything outlined above forms the basis of your bootstrap for a new computer, which I alluded to in Automate the bootstrapping of your new computer.
