GNU Bourne Again SHell

What is GNU Bourne Again SHell?

Bash is a powerful and flexible shell that serves as the command language interpreter for the GNU operating system. As an sh-compatible shell, Bash incorporates useful features from the Korn shell (ksh) and C shell (csh), and is designed to conform to the IEEE POSIX P1003.2/ISO 9945.2 Shell and Tools standard. With its focus on functionality and versatility, Bash provides significant improvements over the standard sh shell for both programming and interactive use, while maintaining compatibility with a majority of existing sh scripts
