The Über-Skeleton Challenge

By Dave Taylor 

I received an interesting message from Angela Kahealani with a challenge: "Here's what I'd like to see in Work the Shell: a full-blown shell script template. It should comply with all standards applicable to CLI programs. more>>

Python Scripts as a Replacement for Bash Utility Scripts

By Richard Delaney 

For Linux users, the command line is a celebrated part of our entire experience. Unlike other popular operating systems, where the command line is a scary proposition for all but the most experienced veterans, in the Linux community, command-line use is encouraged. more>>

Internationalizing Those Bash Scripts

By Louis Iacona 

The first software that I was actually paid to develop was a 2-page shell script that prompted the user for a dozen or so pieces of information, before launching a set of cooperating processes. Those processes formed the core of a performance evaluation suite for the public telephone network - a rather sizable system for its day with high visibility. more>>

Bash Co-Processes

By Mitch Frazier 

One of the new features in bash 4.0 is the coproc statement. The coproc statement allows you to create a co-process that is connected to the invoking shell via two pipes: one to send input to the co-process and one to get output from the co-process. more>>

Globstar: New Bash Globbing Option

By Mitch Frazier 

In shell-speak, globbing is what the shell does when you use a wildcard in a command (e.g. * or ?). Globbing is matching the wildcard pattern and returning the file and directory names that match and then replacing the wildcard pattern in the command with the matched items. Bash version 4.0 adds a new globbing option called globstar which treats the pattern ** differently when it's set. more>>

Fabric-Based Computing Enables Optimized Hyperscale Data Centers

Today’s modular x86 servers are compute-centric, designed as a least common denominator to support a wide range of IT workloads. Those generic, virtualized IT workloads have much different resource optimization requirements than hyperscale and cloud applications. They have resulted in a “one size fits all” enterprise IT architecture that is not optimized for a specific set of IT workloads, and especially not emerging hyperscale workloads, such as web applications, big data, and object storage. In this report, you will learn how shifting the focus from traditional compute-centric IT architectures to an innovative disaggregated fabric-based architecture can optimize and scale your data center.

Red Hat White Paper: Using an Open Source Framework to Catch the Bad Guy

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6

Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.
