One of the best AWK pages that I've seen is Bruce Barnett's page for awk:

Awk - A Tutorial and Introduction - by Bruce Barnett

He also maintains an excellent page for sed:

Sed - An Introduction and Tutorial

Other good resources include:

The GNU Awk User's Guide (Man pages for GNU awk, assuming that you're using Linux, or have Linux packages installed)

sed, a stream editor

Happy hunting.

Of the many collections of "sed" examples this contains simple and complex examples which have practical uses. Not verified. Always test on expendable test data files.

sed = stream line editor ... Basically read a line/word/character and apply changes and send to screen STDOUT ( most of time).

awk = more of programming language can be easier to write compared to sed

if you are looking to answer an interview question then you need to practice a bit on each. or if you are writing one liner's .... try searching web.

Can't see any urgent matter in this - as some already said this is very very easy stuff you can google your own. Place something like this in a more appropriate subforum next time, ty. Thread closed.
