Using sed to delete range of lines except the end pattern

Tags:

sed

awk

input.txt:

blah1
blah2
start_pattern
blah3
blah4
blah5
end_pattern
blah6
blah7

I would like input.txt to become:

blah1
blah2
end_pattern
blah6
blah7

I tried the following, but it didn't work.

sed -i "/start_pattern/, /end_pattern/{$!d}" input.txt
