Correction to grep Article

In the syntax section of the April article “grep: Searching for Words”, Jan Rooijackers mistakes shell expansion with regular expressions. The grep command grep flip * does indeed use the regular expression “flip”, but it never sees the *, as the shell has expanded that asterisk to be each file in the directory. Mr. Rooijackers incorrectly explains that grep is using the asterisk as a regular expression meaning all the files in the directory.

Minor Correction

Linux Journal is amazing, and issue #60 was no exception. However, I'd like to point out a minor typing mistake in the article “Linux 2.2 and the Frame-Buffer Console”; the text says the frame buffer device files are /dev/fd*. Shouldn't that be /dev/fb*?

Yes, you found a typo we missed. Thanks for pointing it out —Editor

URL in May 99

I received my free issue of Linux Journal today and began reading the article “Creat: An Embedded Systems Project” by Nick Bailey. It contains the URL http://ryeham.ee.ryerson.ca/uCinux/ for the Linux/Microcontroller home page. I tried to access this site, with no luck. Can you tell me the correct URL?

Pesky typos! The correct URL is http://ryeham.ee.ryerson.ca/uClinux/ —Editor

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.
