springclean is a command line tool for cleaning up log files. It can select files based on name (exact or regex), age, or a combination of both. You can preview changes, and confirm before running each action. For each action you can find how much disk space has been freed, compress, move to another directory or remove your files, and create an audit trail with syslog.
sqlamp is an implementation of Materialized Path, an efficient algorithm for working with hierarchical data structures. sqlamp uses (and depends on) SQLAlchemy. Materialized Path is a way to store (and fetch) trees in a relational databases. It is the compromise between Nested Sets and Adjacency Relations in respect to simplicity and efficiency.
sqlmap is a penetration testing tool that automates the process of detecting and exploiting SQL injection flaws and taking over of database servers. It comes with a detection engine, many niche features, and a broad range of switches including database fingerprinting, data fetching from the database, and accessing the underlying file system and executing commands on the operating system via out-of-band connections.
ssh-ident allows you to have a single line in your .bashrc, then let it take care of loading ssh-agents when first needed, load all the necessary keys, and share ssh-agents across login consoles. If you have multiple identities for the same account, it is able to load different keys depending on the host you connect to or the path you are working from. At the same time, it keeps the ssh-agents separated and forwards only the keys which are needed for the specific host. It also allows you to specify ssh-add options, so you can automatically lock keys which are unused for a certain time, or have a confirmation request every time a specific key is used.
ssh-multiadd adds multiple ssh keys to the ssh authentication agent. These may use the same passphrase. When run without arguments, it adds $HOME/.ssh/identity and $HOME/.ssh/id_dsa. Alternative file names can be given on the command line or in the configuration file. It uses ssh-askpass if necessary. Unlike ssh-add, if any of the keys use the same passphrase, you will only need to enter each unique passphrase once, and keys that are already added will not be prompted for again.
