I have two computers: one at work and one at home. Dropbox has been a fantastic way for me to effortlessly share files between the two.

I often setup aliases, and other bash configurations, in my .bash_profile to make life easier. Though, sometimes I’m not so careful; I’ll set something up on one computer, but forget to do it on the other.

Sharing configurations across two computers is easy thanks to Dropbox. Here’s how:

1. Create a file in your Dropbox. I called mine .bash_profile_shared, and stored it in the root Dropbox folder, for consistency’s sake, but you can call whatever you like, and store it anywhere on Dropbox.
2. Edit your local .bash_profile file, and add this as the first line of your script: source ~/Dropbox/.bash_profile_shared, or whatever you named your shared Dropbox file.
3. Reload your Terminal, or source ~/.bash_profile

And, that’s it. Anytime you’d like to share a config, just add it the .bash_profile_shared file in Dropbox (and wait for it to sync).
