DASH is a POSIX-compliant implementation of /bin/sh that aims to be as small as possible. It does this without sacrificing speed where possible. In fact, it is significantly faster than bash (the GNU Bourne-Again SHell) for most tasks. To patch in fixes from current git, add 'USE_GIT_PATCH=yes' to the command line when building, like this: # USE_GIT_PATCH=yes sh dash.Slackbuild or, if you use fakeroot to build: $ fakeroot env USE_GIT_PATCH=yes sh dash.SlackBuild
