GNU parallel is a shell tool for executing jobs in parallel locally or using remote computers. A job is typically a single command or a small script that has to be run for each of the lines in the input. The typical input is a list of files, a list of hosts, a list of users, a list of URLs, or a list of tables. If you use xargs today you will find GNU parallel very easy to use, as GNU parallel is written to have the same options as xargs. If you write loops in shell, you will find GNU parallel may be able to replace most of the loops and make them run faster by running several jobs in parallel. GNU parallel makes sure output from the commands is the same output as you would get had you run the commands sequentially. This makes it possible to use output from GNU parallel as input for other programs.
highest is a program that efficiently finds the n highest (or lowest) numbers in a list of numbers on stdin. The traditional way of computing this using GNU sort should have a running time of O(n log n), where n is the number of numbers to check. Highest should have a running time of O(n log m), where m is the number of numbers you want to keep. A graph comparing the performance of highest to that of GNU sort is provided.
jared (just another registry editor) is a Java library for editing the Windows registry. It reads a registry file into memory and allows modifications and rewriting of the file. It also contains a command line program for mods using a .reg file. The code supports gcj. jared is particularly appropriate for modifying or analyzing registry hives offline.
Belier allows opening a shell or executing a command on a remote computer through an SSH session. The main feature of Belier is its ability to cross several intermediate computers before realizing the job. You can execute commands with any account available on the remote computer. It is possible to switch an account on intermediate computers before accessing the final computer, and Belier will generate one script for each final computer to reach.
netcf is a library and command line tool for configuring networking on Linux machines in a platform-independent way, using the platforms native configuration mechanisms. Supported are all the various ways in which physical interfaces, bridges, bonds, and VLANs can be combined. The configuration of a network connection is described in an XML format that emphasizes the logical relationship between the interfaces involved, e.g. a bridge connection describes the bridge interface itself and all the interfaces initially enslaved to it. Interoperability with existing network configuration tools is guaranteed since netcf relies only on native network configuration files, both for reading and writing them. Modifying network configuration with netcf has exactly the same effect as modifying the native configuration files directly, and netcf and other tools can be used interchangeably.
Petit was developed to quickly analyze syslog and Apache log files in large environments. It can also be used for word discovery within log data. It is a general purpose tool that can do hashing, word counts, and command line graphing of Apache and syslog files. It is designed to be a standard Unix tool that can be employed with pipes or by opening files. Petit works by sifting data with standard patterns and allows for custom filters and fingerprints. This leaves the analyst with data that is both varied and interesting.
