Two new bashisms

I learned about two bash features I hadn’t known about today.

From a colleague, GLOBIGNORE. A colon-separated glob of files to ignore when expanding globs. Helpful behavior when set to “*~” and used with grep.

From the Git FAQ, in a section explaining that it breaks the Git build process, CDPATH. A colon-separated search path to use when you type cd. Possibly useful to refer to subdirs of ~ or other common areas. Seems like it’s prone to break a ton of scripts if exported though.
