Learning More About bash Documentation

Problem

You’d like to read more about bash but don’t know where to start.

Solution

Well you’re reading this book, which is a great place to start! The other O’Reilly books about bash and shell scripting are: Learning the bash Shell by Cameron Newham (O’Reilly) and Classic Shell Scripting by Nelson H.F. Beebe and Arnold Robbins (O’Reilly).

Unfortunately, the official bash documentation has not been easily accessible online—until now! Previously, you had to download several different tarballs, locate all the files that contain documentation, and then decipher the file names to find what you wanted. Now, our companion web site (http://www.bashcookbook.com/) has done all this work for you and provides the official bash reference documentation online so it’s easy to refer to. Check it out, and refer others to it as needed.

Official documentation

The official bash FAQ is at: ftp://ftp.cwru.edu/pub/bash/FAQ. See especially “H2) What kind of bash documentation is there?” The official reference guide is also strongly recommended; see below for details.

Chet Ramey’s (the current bash maintainer) bash page (called bashtop) contains a ton of very useful information (http://tiswww.tis.case.edu/~chet/bash/bashtop.html). Chet also maintains the following (listed in bashtop):
