Learning the bash Shell

New edition of a guide to the Free Sofware Foundation's "Bourne Again Shell." Intended both for those who are interested in bash as a user interface as well as for those who want to exploit its powerful programming capabilities. Coverage includes shell programming, bash's advanced command-line features, installation of the shell, and configuring and customizing bash. This edition updates information to bash version 2.0, including information on one- dimensional arrays, parameter expansion, conformity with POSIX.2 standards, security improvements, and the bash shell debugger. The first thing users of the Linux operating system come face to face with is the shell. "Shell" is the UNIX term for a user interface to the system -- something that lets you communicate with the computer via the keyboard and display. Bash, the Free Software Foundation's "Bourne Again Shell," is the default shell for Linux.
