Bblog or Bashblogger uses a combination of standard unix applications such as vi, ls, sed, mv to perform the task of blogging from the terminal. Bblog uses vi by default but the configuration file can be edited to use other more convenient editors like, pico, nano or emacs.

Bash Blogger themes are generated with CSS, where you can edit the existing theme or create your own.
