1. Introduction

Bash (Unix shell) - Wikipedia

This is an sh-compatible shell that incorporates useful features from the Korn shell ksh and the C shell csh. It offers functional improvements over sh for both programming and interactive use. In addition, most sh scripts can be run by Bash without modification. The maintainer also has a Bash page which includes Frequently Asked Questions. Documentation for Bash is available online, as is documentation for most GNU software. Announcements about Bash and most other GNU software are made on info-gnu gnu.

Bash Shell Scripting

Bash is a command processor that typically runs in a text window where the user types commands that cause actions. Bash can also read and execute commands from a file, called a shell script. Like most Unix shells, it supports filename globbing wildcard matching , piping , here documents , command substitution , variables , and control structures for condition-testing and iteration. The keywords , syntax , dynamically scoped variables and other basic features of the language are all copied from sh.
