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.
Unhide.rb finds hidden processes on your system. It looks for active processes in many different ways. Processes found by some means but not others are considered to be "hidden", and are reported to the user. Unhide.rb is a Ruby rewrite of the original Unhide, which was written in C. Unhide.rb performs the same checks as the original, but is 10 times faster in only half as much code, and has better diagnostics when hidden processes are found.
