prwd — universal shell prompt
prwd is a replacement for your shell's PS1, it provides a simple templating language with commands to customize your prompt. prwd keeps your prompt consistent between shells, provides fast template commands to display contextual information such as hostname, path, current git/hg branch without an inordinate amount of slow shell scripting.

defines all the configuration, overrides PRWD and the internal defaults. See prwdrc(5) for configuratiom syntax and parameters.

prwdrc(5), pwd(1), csh(1), ksh(1), sh(1), getcwd(3)
