Deleting a certain line on linux

Question

For example I have a caf.txt file and I want to delete a "donut" word in the document without entering the document on linux .How can I do it?

You want to delete just the word or the line containing that word? — Utsav, Dec 22 '16 at 06:50

To delete just the word "donut"

sed -i 's/donut//g' caf.txt

To delete lines that contain the word "donut"

sed -i '/donut/d' caf.txt

What I do is:

sed '/text_to_delete/d' filename | sponge filename

This will make the change to the source file.
