The awk Utility
Scripting languages and specialty tools that allow rapid development have been widely accepted for quite some time. Both awk and sed deserve a spot on any Linux developer's and administrator's workbench. Both tools are a standard part of any Linux platform. Together, awk and sed can be used to implement virtually any text filtering application—such as perform repetitive edits to data streams and files and generate formatted reports.
The most current reference book for both awk and sed is the O'Reilly release awk and sed by Dale Dougherty and Arnold Robbins. Also see Effective AWK Programming by Arnold Robbins (SSC). For an immediate on-line synopsis on your Linux system, use the man command as follows:
I hope the information provided here is useful and encourages you to begin or expand your use of these tools. If you exploit what awk and sed offer, you will most certainly save development time and money. Those who know how to quickly apply sharp tools to seemingly complex problems are handsomely rewarded in our field.

Until recently, IBM’s Power Platform was looked upon as being the system that hosted IBM’s flavor of UNIX and proprietary operating system called IBM i. These servers often are found in medium-size businesses running ERP, CRM and financials for on-premise customers. By enabling the Power platform to run the Linux OS, IBM now has positioned Power to be the platform of choice for those already running Linux that are facing scalability issues, especially customers looking at analytics, big data or cloud computing.
￼Running Linux on IBM’s Power hardware offers some obvious benefits, including improved processing speed and memory bandwidth, inherent security, and simpler deployment and management. But if you look beyond the impressive architecture, you’ll also find an open ecosystem that has given rise to a strong, innovative community, as well as an inventory of system and network management applications that really help leverage the benefits offered by running Linux on Power.Get the Guide
