ttyload is a little *NIX utility which is meant to give a color-coded
graph of load averages over time.
ipcserver and ipcclient are command-line tools for building local-domain
client-server applications. They conform to the UNIX Client-Server
Program Interface, UCSPI.
ipcserver listens for connections on a local-domain stream socket, and
runs a program for each connection it accepts. The program environment
includes variables that hold the local and remote socket addresses, and
the effective user and group IDs of the process that called connect.
ipcserver offers a concurrency limit on acceptance of new connections,
and selective handling of connections based on client identity.
ipcclient requests a connection to a local-domain socket, and runs a
program. The program environment includes a variable that holds the
local socket address.
ipcperl is an example of an ipchandle server. It invokes a perl
subroutine for each request.
The upsdaemon is a simple program to monitor APC-Pro series UPSes.
When the power fail, the UpsDaemon it effects shutdown the system.
USB_ModeSwitch is (surprise!) a mode switching tool for controlling
"flip flop" (multiple device) USB gear.
USB_ModeSwitch makes this process easy to handle by taking the important
parameters from a configuration file and doing all the initialization
and communication stuff, with heavy help from "libusb". It is mainly
used automatically - via udev events and rules - to do the switch
without any user interaction. But it can also be run as a command line
tool, usually when trying to make unknown devices work with it.
uschedule is not cron and uschedule is not at - it does offer similar
functionality but is not intended to be a drop-in replacement. It works
differently. It's designed to be different.
vbetool is a small application that executes code from the BIOS of your
video card. This is mostly useful for reinitialising the hardware,
for instance after ACPI suspend/resuming.
Videogen calculates XFree86 modelines.
Virtualmin is a virtual hosting management system written by Jamie
Cameron, that integrates cleanly into the Webmin system administration
tool.
Window Maker dock app showing load average as a flame.
Not terribly useful, but looks cool.
wtail does the equivalent of tail -f on several files at once. The screen
is split into as many parts as there are files to watch.
