Supported Versions of Bash
Versions 5.x and 4.x are supported on macOS, Linux, and Windows.
Version 3.x and older isn’t supported by bashdb. macOS comes with version 3.2, which was released in 2006. Please update to a newer version to use the debugger integration of BashSupport Pro. You can do this via Homebrew, for example.
Supported Operating Systems
Debugging is supported on macOS, Linux and Windows.
Two output consoles are available. The first is to interact with your script (stdin and stdout). The second console is used to separate the communication with bashdb from the regular input and output of the debugged script.
