imapsync is a tool for facilitating incremental recursive IMAP transfers from one mailbox to another. It is useful for mailbox migration or backup, and reduces the amount of data transferred by only copying messages that are not present on both servers. Read, unread, and deleted flags are preserved, and the process can be stopped and resumed. The original messages can optionally be deleted after a successful transfer.
zzuf is a transparent application input fuzzer. Its purpose is to find bugs in applications by corrupting their user-contributed data, which frequently comes from untrusted sources on the Internet. It works by intercepting file and network operations and changing random bits in the program's input. zzuf's behavior is deterministic, making it easier to reproduce bugs.
Flex Bison C++ Template is a code template that can be used to integrate a Flex scanner and Bison parser pair into a modern C++ program. These two universal tools are very difficult to incorporate into a good C++ design. The template utilizes both Flex and Bison in C++ mode and their output are encapsulated into classes. Thus the lexer and parser become fully reentrant, and multiple distinct lexer-parser pairs can easily be linked into one binary. The code implements a simple infix-notation calculator as an example, which can be used as a starting-point for you to insert your grammar.
bash argsparse is a high-level argument parsing library for bash. Its purpose is to replace the option parsing and usage describing functions commonly rewritten in all scripts. Its features include automatic help message generation, user input checking (type checking, enumerations, etc.), and option properties (mandatory options, option aliases, options excluding each others, etc.). It is implemented for bash version 4. Prior versions of bash will fail at interpreting the code.
icli is a command line interface to the Icinga monitoring software. You can use it to list service/host status with many filtering options, schedule rechecks, and acknowledge service problems. Basic support for viewing the command queue and scheduled downtimes is also present. It is largely compatible with Nagios.
