Yes, just follow the book and you'll be fine. As you gain more experience and learn more you'll begin to understand more about how it all works and you'll learn (through trial and error) what you can change and what you should leave alone. > > One more thing; sometimes I know why to run the script but I don't know how > script works exactly. the main example is sed.

No, you don't need to understand. But if you're interested there are lots of good resources available online: http://sed.sourceforge.net/sed1line.txt And indeed some good old fashioned books that you could read: http://www.amazon.co.uk/Mastering-Regular-Expressions-Jeffrey-Friedl/dp/0596528124/ http://www.amazon.co.uk/sed-Nutshell-Handbooks-Dale-Dougherty/dp/1565922255/ Andy -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
