PCRE is a widely used Unicode-compatible regular expression engine. It implements Perl5 regex syntax and semantics, some Python, .NET and Onigurama extensions. It uses just-in-time compilation, has consistent escaping rules, and allows for recursion, assertions and conditional patterns or complex subroutines and callouts, thus goes far beyond classic regular expressions.
rpmorphan finds "orphaned" RPM packages on your system (packages which have no other packages depending on their installation). Console and graphical interfaces are provided. It is clone of the deborphan Debian program, but for RPM packages. It also provides some others RPM tools: rpmusage, rpmdep, and rpmduplicates.

The general goal is to provide a database-style architecture to handle email, not just for storage but at the application level too. Fast and shared access, fine-tuned security, robust storage, consistent backups, auditing, statistics, and custo
gpgpwd is a terminal-based password manager. It stores a list of passwords and their associated usernames in a GnuPG-encrypted file, and allows you to easily retrieve, change, and add to that file as needed. It also generates random passwords which you can use, easily allowing you to have one "master password" (for your gpg key), with one unique and random password for each website or service you use, ensuring that your other accounts stay safe even if one password gets leaked. gpgpwd can als
Afick is a fast and portable intrusion detection and integrity monitoring system, designed to work on all platforms (it only needs Perl and a few standard modules), including Windows, Linux, Unix. The configuration syntax is very close from tripwire/aide.

The IPTables::Parse package provides an interface to parse iptables or ip6tables rules on Linux systems through the direct execution of iptables/ip6tables commands, or from parsing a file that contains an iptables/ip6tables policy listing. Note that the 'firewalld' infrastructure on Fedora21 is also supported through execution of the 'firewall-cmd' binary. By default, the path to iptables is assumed to be '/sbin/iptables', but if the firewall is 'firewalld', then the '/usr/bin/firewall-cmd' is u
Delta Reporting is a central logging service for CFEngine. CFEngine promises and classes are stored in a central database and made available for advanced searches and reports via a modern Web interface and the command line.
RemoteBox is a client for administring guest VMs on a VirtualBox server. It provides a complete GTK interface similar to VirtualBox itself, and allows direct interaction (RDP) with the running system from a remote "client" machine. All system / virtualization properties can be influenced, devices edited, networking setup changed, and VM snapshots be made.
Perl is a family of high-level, general-purpose, and dynamically interpreted programming languages. It borrows some syntax from C, Unix Shells, and AWK or SED, and more or less reinvented modern regular expressions. Perl 5 is the current mainstream version, with over 20 years of development. CPAN provides a modular packaging system, and allows Perl to be used for web applications, graphics programming, networking, system adminstration, and many sciency applications.
minor feature: Unicode 8.0 is now supported.
Incompatible Changes: The / C/ character class has been removed. It was deprecated since 5.20, and now leads to a compile-time error.
chdir('') no longer chdirs home.

The Python module bond supports transparent remote/recursive evaluation between Python and another interpreter through automatic call serialization. In poorer words, a bond lets you call functions in other languages as they were normal Python functions. It also allows other languages to call Python functions as if they were native. Remote output is also transparently redirected locally, and since the evaluation is performed through a persistent co-process, you can actually spawn interpreters o
OpenDKIM is an open source implementation of the DKIM (RFC6376) email sender authentication system, derived from dkim-milter. It also supports ADSP/RFC5617, Vouch by reference/RFC5518, and experimentally ATPS/RFC6541. It works with any MTA supporting the sendmail milter API, such as Postfix. OpenDKIM provides a Lua-scriptable policy engine, LDAP and SQL database support, and statistic/reporting tools.
Ruby is a modern, dynamic, post object-oriented/functional programming language. It blends syntax and features from Perl, Lisp, Eiffel, Ada and Smalltalk, with flexible expressions, dynamic but strict typing, mixins and explicit scoping. It's available in different runtimes, on most platforms, and a complete extension ecosystem.
LCMC is a GUI for managing server clusters based on Pacemaker, Corosync, Heartbeat, DRBD, KVM, XEN and LVM. Server management is implemented in Perl, while the management console is Java-based.

tblutils complements the usual unix tools like cut and paste by providing enhanced versions that support column labels through-out, so that you can extract columns by name (tblcut), filter data using a mathematical expression (tblfilter), re-order columns without caring about the column index (tblcsort), join multiple files on a common index without having to pre-sort them (tblmerge), and much more.
GnuCash is a personal finance and small-business accounting software. It provides a check-book like register GUI to enter and track bank accounts, stocks, income and expenses, for double-entry accounting. It also allows to manage stock/bond/mutual fund accounts, generate graphs and reports, supports QIF/OFX/HBCI import, and transaction matching, common calculations and scheduling. It's still simple to use.
fwsnort translates SNORT rules into iptables rules on Linux systems and generates a corresponding iptables policy in iptables-save format. This ruleset allows network traffic that matches Snort signatures (i.e. attacks and other suspicious network behavior) to be logged and/or dropped by iptables directly without putting an interface into promiscuous mode or queuing packets from kernel to user space. Note that fwsnort can also build an iptables policy that combines the string match extension wit
MDBM is a very fast memory-mapped key-value store with a simple interface and lots of features. It was originally based on SDBM by Ozan Yigit, and enhanced by Larry McVoy et al (at SGI). Yahoo! further enhanced it, where it has been in production use for over a decade, serving Terabytes of data.
SQL::Yapp is a Perl module which embeds SQL completely and safely into Perl. It checks SQL syntax at compile time and fully parses SQL to allow usage of any Perl scalars, arrays, and hashes in an intuitive and safe way. It makes SQL injections virtually impossible while making you feel as if SQL syntax were native to Perl.
