This text is a brief description of the features that are
present in the Bash shell. This is Edition 2.3, last updated 20
January 1999, of `The GNU Bash Reference Manual', for `Bash',
Version 2.03. Copyright (C) 1991, 1993, 1996 Free Software
Foundation, Inc. Bash contains features that appear in other
popular shells, and some features that only appear in Bash. Some
of the shells that Bash has borrowed concepts from are the
Bourne Shell (`sh'), the Korn Shell (`ksh'), and the C-shell
(`csh' and its successor, `tcsh'). The following menu breaks the
features up into categories based upon which one of these other
shells inspired the feature. This manual is meant as a brief
introduction to features found in Bash. The Bash manual page
should be used as the definitive reference on shell behavior. *
