zmeter is a serial interface for the RadioShack 22-812 digital multimeter. It listens to the specified serial port and prints the meter reading on standard output (stdout). It operates by waiting for data from the digital multimeter to appear on the serial port and then passing that data to a child process to be formatted and output. It was derived from slsnif with most of the interesting features cut out and a small amount of original code added to support the 22812 data format.
Zoem is a general-purpose macro/programming language that submits text to a two-stage transformation process. Macro expansion and interpretation is followed by application of customizable character filtering rules. Zoem supports inside-out evaluation, comprehensive IO, control operators, iteration, dictionary stacks, multidimensional data storage, arithmetic expressions, regular expressions, system commands, and more.
Zoneadm is a CGI application to allow a DNS hosting site to delegate simple zone change privileges to remote users via a web interface. It allows a remote user the ability to make A, CNAME, PTR, and MX record changes to a zone that the DNS site administrator has given them permission to modify. It does some sanity checking on the information entered by the user, but it may not be foolproof and assumes some knowledge of DNS resource records by the users.
zssh (Zmodem SSH) is a program for interactively transferring files to a remote machine while using the secure shell (ssh). It is intended to be a convenient alternative to scp, allowing to transfer files without having to open another session and re-authenticate oneself. zssh is an interactive wrapper for ssh used to switch the ssh connection between the remote shell and file transfers. Files are transferred through the zmodem protocol, using the rz and sz commands.
zufall is a simple program to change the background periodically. It takes one or more directories with images as a parameter (no GUI) and sets a randomly chosen image as background. If there is a border remaining, its color is the average color of two corners of the image. This mostly fits the image very well. It doesn't work if the root window is hidden by another program, like in Gnome or KDE. However, it is possible to execute a configurable command to effect the change whenever the image is supposed to change. A script to do this in Gnome is included.
