Bash is a Unix shell and command language written by Brian Fox for the GNU Project as a free software replacement for the Bourne shell. Released in 1989, it has been distributed widely as the shell for the GNU operating system and as a default shell on Linux and OS X.

In 2015 Prospect One was asked to design a new logo for Bash, after which 30,000 people voted for the best iteration. You can download the official bash logo below
