If you mentioned WHICH lines in that range you'd like
to remove, maybe?

Cheers,
Tink

The command to be used was
sed '2,10d' a.org > b.txt
this would delete line ranging from 2 to 10 including them.
It looks so easy. but it came after a lot of research

Congratulations!! Homework or not, you are on the path to total success. Look also at addressing by content---not just line number.
eg:
sed '/text/,/F1/d oldfile > newfile
