Bash is one of the most popular "shell," or command language interpreters, used with the Unix operating system. Bash is an sh-compatible shell that 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 specification (IEEE Working Group 1003.2). It offers functional improvements over sh for both interactive and programming use. What"s more Bash is 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, Windows 95, and Windows NT. iUniverse.com Computer Books are composed of freely available online computer manuals, industry standard specifications, and electronically distributed computer-programming guides.
