I'm struggling to implement the sed range pattern command on groovy script.

This is how I'm attempting to implement the command in groovy script:

 def range = sed -n -e '/Word A/,/Word D/ p'
 def result = cat sample.txt | range.execute()

This is the content of the sample.txt file:

Word A
Word B
Word C
Word D
Word E
Word F

This is the output I want:

Word A
Word B
Word C
Word D

Now, the error that is returned to me when I run it is:

sed: unmatched '/'

I believe the reason why I'm getting this error is because in the actual sed command, I need to somehow group the range pattern altogether because I feel and in fact I've tested it, the sed command only applies to the first range, i.e. "WORD A" and then it reads the next "/" as a literal character rather than a character that encapsulates the next pattern which is WORD D.

I've tried to use single quotes and double quotes but upon running my script, I get an error saying either: sed unmatched "'" or sed unknown command.

Can someone please help resolve this issue as it's taken me two days to work this out.

Thanks!
