Bash is the JavaScript of systems programming. Although in some cases it's better to use a systems language like C or Go, Bash is an ideal systems language for smaller POSIX-oriented or command line tasks. Here's three quick reasons why:

• It's everywhere. Like JavaScript for the web, Bash is already there ready for systems programming.
• It's neutral. Unlike Ruby, Python, JavaScript, or PHP, Bash offends equally across all communities. ;)
• It's made to be glue. Write complex parts in C or Go (or whatever!), and glue them together with Bash.

This document is how I write Bash and how I'd like collaborators to write Bash with me in my open source projects. It's based on a lot of experience and time collecting best practices. Most of them come from these two articles, but here integrated, slightly modified, and focusing on the most bang for buck items. Plus some ne

Dropbox: (LaunchServices) [http://com.apple .launchservices.default] Local database thinks system build version is <private>, but the OS really is <private>.

Right above that I got this line:

Install pip packages with homebrew:

Install the brew-pip package brew install brew-pip

Add Homebrew's pip path to your PYTHONPATH environment variable (you probably should add this to some sort of shell initialization file like ~/.bashrc or ~/.zshrc) export PYTHONPATH=$(brew --prefix)/lib/python2.7/site-packages

Now install any pip packages with Homebrew! brew pip Glances
