BASHISH is a theme engine for bourne style shells. (proven to be fully customizeable with bash, zsh, ksh93, pdksh, and slackware ash) (partially customizable but fully useful on tcsh, rc and akanga) With BASHISH you can change: the prompt the window title, the font, the background image, background and foreground colors, the default ansi colors, Of course all these features can easily be turned off. BASHISH also introduces a standard for writing multi-shell prompts, making themes run unmodified on all shells! If the features above wasn't enough for you, you can easily add your own features thanks to the scalable design!
