iStats 
iStats is a command-line tool that allows you to easily grab the CPU temperature, fan speeds and battery information on OS X. If you'd like to see more data available feel free to open an issue.
Warning
A bug in Ruby and Apple XCode 5.1 onwards (new CLANG version) might make it impossible to install this gem if you are using Ruby from the Xcode command-line tools package. If you see an error when the gem is building the native extension try to use this command to install iStats:
sudo ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future gem install iStats
If you are using RVM or homebrew to manage your Ruby installation you should be fine.
