bashdb, kshdb, and zshdb are debuggers for Bash,
ksh, and zsh scripts respectively. The debugger
command interface is modeled on the gdb command
interface. Front-ends supporting bashdb include
GNU-Emacs and ddd.

There is now an easy way to evaluate the line of code that is about to be executed or the expression part of conditional statements. You can go into a nested shell that imports existing variables and function names. Display expressions and "set/show autolist" were added. There were numerous changes to bring this debugger more in line with bashdb and zshdb. Code was refactored to support maintenance and future growth.
The debugger "list" command centers around a line unless given a start and end line number. Use "list>" for a non-centering list. This version has been tested to work on bash version 4.2. Some short abbreviations of commands have been dropped. Use "alias" to add alias for dropped short commands. The "display" command is more like gdb. Emacs lisp code has been removed. Please use the multi-debugger code from http://github.com/rocky/emacs-dbgr instead. Numerous little bugs were fixed.
The debugger "list" command has seen changes. By default, it centers around the selected line. Use "list>" to force starting at the line. The command-processing code has been changed to simplify it, make it more dynamic, and allow for better expansion. As a result, some short abbreviations of commands have been dropped. Use "alias" to add back any that you want.
