sudo sed -i s/UTC=yes/UTC=no/ /etc/default/rcS I am not seeing at this point where the -i fits in anywhere with the short command. Thank goodness I did not run it yet. I can see how this can be fun and people can become mean. Every command with root can do something 1 false move and your 'taking it'. there is no -i within sed . Happy New Year.

Hi Paul, Before you spend any money, I might recommend the WikiBook on the topic. WikiBooks are freely available resources on many topics. Here's a link to the Sed WikiBook: http://en.m.wikibooks.org/wiki/Sed In addition, I've found this resource to be useful in learning Sed: http://www.grymoire.com/Unix/Sed.html It's not a book exactly, but it has helped me locate a number of useful examples that allowed me to better explore the tool. If you're looking for something more, the O'Reilly Guide to Awk and Sed seems to be well-reviewed, and may available at a bookseller near you. Best of luck, Brandon On Jan 2, 2015, at 11:07 PM, paul g <pj.world at hotmail.com> wrote: I would like to purchase the best book about 'sed' that I can buy could anyone please recommend this?
