HI,

sed '/AAA/,/BBB/p' <file> gives me

AAA
some text
some text
BBB


Now I want is the out put without AAA or BBB. How is this possible
with a single sed command? I tried following but didn't work -
sed '/AAA/,/BBB/{ 1d; $d; p; }' <file>

sed -e '1,/AAA/d' -e '/BBB/,$d'

Mind using awk?

awk '/BBB/{f=0};f;/AAA/{f=1}'

Following is the output of sed command I used & not the file content -
AAA
some text
some text
BBB
The file contains so many other blocks too. So the command you gave
doesn't help. It would remove the first & last line from the file &
not from this filtered block. Correct me if I'm wrong.

It works. Please explain it to me. I'm not so good with awk. Also I
find the Second regex is used first. Why is this order important.
