I just came across your video, I think is excellent, straightforward information with great practical examples. Perhaps an early introduction to delimiters rather than late, could be useful for beginners. Keep up the good work and thank you.

when I pipe awk command into sed -i.bak ... I get sed: no input files. How can I save changes to the original input file.

I have a quick question. I noticed that when you removed the comment lines, there was one comment that remained. Is that due to the 'tab' in front of the pound sign?

[yanghwanlim]

Hey!! Why are you modifying the /etc/passwd file which is some what very important file, I think. Not a good example! Don't you think?
