New Features In Bash Version 4.x - Part 1

Apr 07, 2010, 16:04 (0 Talkback[s])

"As I mention in the introduction to The Linux Command Line, the command line is a long lasting skill. It's quite possible that a script that you wrote ten years ago still works perfectly well today. But even so, every few years the GNU Project releases a new version of bash. While I was writing the book, version 3.2 was the predominate version found in Linux distributions. In February of 2009 however a new major version of bash (4.0) appeared and it began to show up in distributions last fall. Today the current version of bash is 4.1 and it, too, is beginning to show up in distributions such as Ubuntu 10.04 and (I presume, since I haven't checked yet) Fedora 13.

"So what's new in bash? A bunch of things, though most of them tend to be rather small. In this series we will look at features that, I feel, are of the most use to ordinary shell users starting with a couple of the small ones."
