path can be used to manipulate a colon-separated list of paths contained in an environment variable such as PATH. New paths can be added either to the beginning or the end of the path list, paths can be removed from the path list, and several checks can be made on the paths contained in the path list. All duplicate paths in the list are removed.
ImageMagick (TM) is a package for the automated and interative manipulation of images. It supports the display and interactive manipulation of images when used with the X Window System. Although the software is copyrighted by ImageMagick Studio, it is available for free and can be redistributed without fee. ImageMagick may be used as a component of both open source and proprietary applications. ImageMagick compiles and runs under Unix, Linux, Windows '95 and later, Apple MacOS, and Compaq VMS. Binary packages are available for most operating systems. Application programming interfaces (APIs) are provided to support development of image processing applications in the C, C++, and Perl languages.
SAC performs login accounting, just like the ac program but with total, per day, per user and per tty. It also performs average usage, hourly profiling, login listing, login clipping and raw wtmp reporting as well as tons of other options. SAC supports Tacacs 3.x/4.x and most Radius accounting files.
KOSd is a modified version of Ascend's RADIUS (derived from Livingston's) daemon that supports GECOS password files in another location than /etc/passwd. The path to the file is configurable in a C file. It's great for segmenting dial-in and email-only users on a dialing pool, supporting both Max units and Xylogics (now Bay) servers from a single password file, and probably others. It will probably work with Cisco or Livingston servers as well by changing the dictionary file and turning off the -DASCEND extensions within the makefile, but you may need to experiment. This product is totally unsupported.
