This is GNU Stow, a program for managing the installation of software packages, keeping them separate (/usr/local/stow/emacs vs. /usr/local/stow/perl, for example) while making them appear to be installed in the same place (/usr/local). Stow was inspired by Carnegie Mellon's "Depot" program, but is substantially simpler. Whereas Depot requires database files to keep things in sync, Stow stores no extra state between runs, so there's no danger (as there is in Depot) of mangling directories when file hierarchies don't match the database. Also unlike Depot, Stow will never delete any files, directories, or links that appear in a Stow directory (e.g., /usr/local/stow/emacs), so it's always possible to rebuild the target tree (e.g., /usr/local).

The symon project consists of three parts; a data monitor, a data consolidator and a data displayer. symon is a is a lightweight system monitor that measures cpu, memory, pf, interface and disk statistics every 5 seconds. It sends this data on to symux for further processing. symon has been designed to inflict minimal performance and security impact -- it can be run as nobody on the system it monitors. symux is a non-privileged daemon that listens to incoming symon traffic. symux can write the incoming symon streams into rrd files. Clients interested in monitoring machine state can also log into symux and receive data as ascii as it arrives.

XCPUSTATE is a system monitor tool. It displays user-, system-, idle-cputime in the form of a bar chart. On some systems it also monitors disk performance. It can also display information about remote hosts using the RSTAT RPC protocol, as perfmeter does.

sysgather is a simple command-line utility for keeping configuration files under version control.

Sysinfo is a shell script, the purpose of which is to automatically gather system information and document the hardware and software configuration of the given host system. The goal is to provide a system operator with descriptive information about an unknown FreeBSD installation.

System-tools-backends is a collection of scripts (mostly Perl) used by gnome-system-tools to perform system administration tasks.

zfs-snapshot-clean ------------------ This is a tool to sieve ZFS snapshots as per given spec a la `pdumpfs-clean'. Typical usage is as follows: for vol in zpool/home zpool/var; do zfs snapshot "$vol@$(date +%Y-%m-%d)" && zfs-snapshot-clean "$vol" done Run `zfs-snapshot-clean -h' for details.

Tenshi is a log monitoring program, designed to watch one or more log files for lines matching user defined regular expressions and report on the matches. The regular expressions are assigned to queues which have an alert interval and a list of mail recipients. Queues can be set to send a notification as soon as there is a log line assigned to it, or to send periodic reports. Additionally, uninteresting fields in the log lines (such as PID numbers) can be masked with the standard regular expression grouping operators ( ). This allows cleaner and more readable reports. All reports are separated by hostname and all messages are condensed when possible.

The Fish provides a graphical UI (with GTK+, Qt and ncurses frontends) to manage and edit system variables stored in /etc/defaults/rc.conf and /etc/rc.conf.

timelimit executes a command and terminates the spawned process after a given time with a given signal. A 'warning' signal is sent first, then, after a timeout, a 'kill' signal, similar to the way init(8) operates on shutdown.
