Introduction

This is Edition 2.3, last updated 20 January 1999,

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.
