While the GNU operating system provides other shells, including a version of csh, Bash is the default shell. Like other GNU software, Bash is quite portable. It currently runs on nearly every version of Unix and a few other operating systems - independently-supported ports exist for MS-DOS, OS/2, and Windows platforms.

在GNU操作系统提供其他shells时,包括csh的一个版本,Bash是缺省的shell。如同其他GNU软件,Bash是非常便携的。它几乎允许于每一个版本的Unix以及其他一些操作系统 - 基于端口提供独立支持如MS-DOS,OS/2以及Windows平台。

Bash is the shell, or command language interpreter, for the GNU operating system. The name is an acronym for the 'Bourne-Again SHell', a pun on Stephen Bourne, the author of the direct ancestor of the current Unix shell sh, which appeared in the Seventh Edition Bell Labs Research version of Unix.

Bash是shell,或者,对于GUN操作系统而言它也叫做指令语言解释器。这个名字源于"Bourne-Again SHell"的首字母缩写,Stephen Bourne的双关语,其直接始祖源自当前Unix shell sh,它始现于贝尔实验室Unix的第七个版本。

Bash is largely compatible with sh and incorporates useful features from the Korn shell ksh and the C shell csh. It is intended to be a conformant implementation of the IEEE POSIX Shell and Tools portion of the IEEE POSIX specification (IEEE Standard 1003.1). It offers functional improvements over sh for both interactive and programming use.

Bash在很大程度上与sh是兼容的,并且它也从Korn shell ksh以及C shell csh纳入了一些有用的功能。它的目的是成为IEEE POSIX Shell的一致实现,以及IEEE POSIX规范(IEEE Standard 1003.1)的工具部分。他提供了sh针对交互及编程方面的功能改善。
