Chgrep searches the input files (or standard input if no files are named) for oldstring and changes them to new string. If some file and file.lock exist then chgrep leaves both files unchanged. This program can be very use- full for mail servers. Chgrep is fast, much faster than grep or sed.

The du2ps reads output of du(1), then generates a figure of hierarchical structure and utilization of each directory. The du2ps is a similar program to xdu, but it produces result as a PostScript file. The default paper is ISO A4, but you can select Letter or ISO A3/B4/B5. You can also specify font name, font size, number of columns and other options.

dvtm 引入窗口管理的新概念：平铺式窗口管理，从而将终端窗口可以类似X11窗口那样平铺管理。 作为一个终端窗口管理器，它能同时打开多个基于终端的程序如vim，mutt，cmus，irssi等。

Cpuid dumps detailed information about the CPU(s) gathered from the CPUID instruction, and also determines the exact model of CPU(s). It supports Intel, AMD, and VIA CPUs, as well as older Transmeta, Cyrix, UMC, NexGen, Rise, and SiS CPUs.

pick allows users to choose one option from a set of choices using an interface with fuzzy search functionality.

Beats is the platform for building lightweight, open source data shippers for many types of operational data you want to enrich with Logstash, search and analyze in Elasticsearch, and visualize in Kibana. Whether you're interested in log files, infrastructure metrics, network packets, or any other type of data, Beats serves as the foundation for keeping a beat on your data. Filebeat is a lightweight, open source shipper for log file data. As the next-generation Logstash Forwarder, Filebeat tails logs and quickly sends this information to Logstash for further parsing and enrichment or to Elasticsearch for centralized storage and analysis.

Freecolor is a `free' replacement that displays free memory graphically as a bargraph. It supports the same options as `free'.

xjobs reads job descriptions line by line and executes them in parallel. It limits the number of parallel executing jobs and starts new jobs when jobs finish. Therefore, it combines the arguments from every input line with the utility and arguments given on the command line. If no utility is given as an argument to xjobs, then the first argument on every job line will be used as utility. To execute utility xjobs searches the directories given in the PATH environment variable and uses the first file found in these directories. xjobs is most useful on multi-processor/core machines when one needs to execute several time consuming command several that could possibly be run in parallel. With xjobs this can be achieved easily, and it is possible to limit the load of the machine to a useful value. It works similar to xargs, but starts several processes simultaneously and gives only one line of arguments to each utility call.

This package provides boot scripts used to enable FreeBSD to run on the Amazon EC2 cloud computing platform. These include: * Downloading the SSH public key which will be used to log in to a newly-launched virtual machine, * Printing SSH host key fingerprints to the console in a standard format used by other EC2 images, * Automatically configuring swap space on EC2 "ephemeral" disks, and * Sending email when an virtual machine first boots and when rebooting after a kernel panic.

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).
