Fileprune will delete files from the specified set targeting a given distribution of the files within time as well as size, number, and age constraints. Its main purpose is to keep a set of daily-created backup files in manageable size, while still providing reasonable access to older versions. Specifying a size, file number, or age constraint will simply remove files starting from the oldest, until the constraint is met. The distribution specification (exponential, Gaussian (normal), or Fibonacci) provides finer control of the files to delete, allowing the retention of recent copies and the increasingly aggressive pruning of the older files. The retention schedule specifies the age intervals for which files will be retained. As an example, an exponential retention schedule for 10 files with a base of 2 will be 1 2 4 8 16 32 64 128 256 512 1024 The above schedule specifies that for the interval of 65 to 128 days there should be (at least) one retained file (unless constraints and options override this setting).

Flasher monitors changes to one or more files, and indicates the number of writes to these files by briefly flashing a console LED once for each write. The flashing sequence is repeated, after a brief pause, until the files have been read. As the files are subsequently read, the number of LED flashes is reduced. When all monitored files have been read, the console LED will be disabled. The most obvious use is to monitor specific system log or mail files. Multiple LEDs can be used. Each possible LED (-c, -n or -s) takes a list of colon-separated file arguments. For example, when invoked as: # ./flasher -s /var/log/messages:/var/mail/root the Scroll Lock LED will flash once for each write made to either of these files, until the files are read. When /var/log/messages has been read, the Scroll Lock LED will continue to flash once for each write that has been made to /var/mail/root, until it also has been read. The list of files can include files that don't yet exist.

ApacheTop was written to display realtime status of access logs

KSystemLog is a system log viewer tool. This program is developed for beginner users, who don't know how to find information about their Linux system, and don't know where log files are.

freebsd-snapshot is a set of convenience frontend tools to mount(8) and mdconfig(8) for the management of UFS2 snapshots. It is also the under-lying tool used in the periodic snapshot scheduler periodic-snapshot(8) and the mounting/unmouning command in the amd(8) map /usr/local/etc/amd.map.snap. It provides the making, expiring, visiting, mounting and unmounting of filesystem snapshots.

A reimplementation of Dan Bernstein's daemontools under the GNU GPL, sharing no code with the original implementation. It currently includes feature-equivalent replacements for argv0, envdir, envuidgid, setlock, setuidgid, softlimit, supervise, svc, svok, svscan, svstat and recordio. It also includes dumblog (a simple multilog replacement), mkservice (a script for automatically creating service directories), anonidentd (an anonimising identd implementation) and ratelimit (a bandwidth-limiting filter along the lines of recordio). All the tools include usage messages; for instance, do "ratelimit -h" for a brief rundown of the options. Please note that this package is *not* a drop-in replacement for daemontools; the internal state files in service directories are different, and the error messages (and a few of the options) aren't quite the same. It's also still somewhat experimental, so I'd recommend sticking with daemontools on production systems until there's a stable release of freedt.

GAI Leds is a GAI applet that displays the keyboard status leds.

fstyp can be used to heuristically detect which filesystem type a device or a partition contains. Useful for backup scripts.

KUser is a tool for managing users and groups on your system.

Scanmem is a simple interactive debugging utility for Linux, used to locate various data in an executing process. This can be used for the analysis or modification of a hostile process on a compromised machine, help in reverse engineering, or to cheat at video games. Brief list of its features: - Interactive command mode, with internal help - Efficient and easy-to-use syntax - Support for different data types: integers, floats, bytearrays, strings - Support for different scan (comparison) types: equal, greater/less than, changed, unchanged, increased/decreased - Set any variable to any value - Detailed information about mappings, allow users to eliminate regions More in GameConqueror, optional PyGTK-based GUI: - User-friendly CheatEngline-alike interface - Modify and lock (freeze) variables - Memory viewer/editor It requires linprocfs(5) to be mounted under /compat/linux/proc to operate.
