The New KornShell—ksh93

The KornShell, written by David Korn at Bell Telephone Laboratories, combined the best features of both of these shells, and added the ability to edit and reenter the current and previous commands using the same keystrokes as either the vi or the Emacs editor as the user desired.
Summary

ksh93, the latest major revision of the KornShell language, provides an alternative to Tcl and Perl. As a programming language, it has comparable speed and functionality to each of these languages. Like Tcl, it is extensible and embeddable with a C language application programming interface. The New KornShell, ksh93, and the Tksh products are available from Global Technologies, Ltd., Inc., 5 West Ave, Old Bridge, NJ 908-251-2840.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
