Basically they are doing the same thing:

Code:

sed -n -e '/text[12]/p' -e '/text1/,/text2/d;p' file

1. '/text[12]/p' - print any lines containing the string 'text1' or 'text2'

2. '/text1/,/text2/d;p' - delete anything from text1 to text2 inclusive and print the rest

Code:

awk '/text1/,/text2/{if(/text[12]/)print;next}1' file

1. /text1/,/text2/ - search between text1 and text2 inclusive, when true go to step 2

2. if(/text[12]/)print;next - if line contains strings 'text1' or 'text2' then print. Whether previous is true or not go to the next record

3. 1 - print all lines not in the boundary test from step 1

Hope that helps :)

Thanks Grail, really appreciate it.
