I'm trying to modify a file using sed. Example file:
apples
bananas
oranges
pears
Using sed I've got:
sed -e '/oranges/i\cherries' -e '1,$s/A/a/' fruit.txt
This just echoes the output to the terminal. The output is in the required format (cherries after bananas, before oranges).
How can I use sed to make the permanent change to the file fruits.txt?
