Xorg. The X.Org project provides an open source implementation of the X Window System.
The development work is being done in conjunction with the freedesktop.org community. The X.Org Foundation is the educational non-profit corporation whose Board serves this effort, and whose Members lead this work. The latest release of the full X.Org stack is X11R7.7, though many individual X.Org modules have had new versions released since then - see the xorg-announce archives for details of those releases. The next full stack release will be X11R7.8.

It is intended to conform to the IEEE POSIX P1003.2/ISO 9945.2 Shell and Tools standard. It offers functional improvements over sh for both programming and interactive use. In addition, most sh scripts can be run by Bash without modification. Tmux. Bash. Bash. WWW.
