log4bash facilitates creating easy to read and easy to parse log files from your bash scripts. Developers have the ability to override pretty much all of the default behavior. If the developer chooses to let a user do so, they can pass flags to a script at run time to control some aspects of the logging output. This includes displaying the logging output to the screen in addition to the log file, and altering the logging level. There is a script included (test.log4bash.sh) that provides working code on how to use all of log4bash's features.
Boscli is a framework to create interactive command line interfaces. It is meant to help developers write interactive shells for domain specific tasks. It provides an easy way to wrap and join together command line apps and utilities and create specific shells with security levels and modes, history, auto-completion, and so on. Using this framework any developer can build an interactive command line interface for configuration or monitor an appliance in a few minutes. Boscli can be used as a "glue code" for an appliance's interface or to create a "homogeneous" administration interface for different systems and applications.
