How to add a character to the end of each line in a file in shell script

Question

I need a script that add a particular character to the end of each line . I am using the command
sed 's/$/ foo/' r.txt

It adds foo to end of each line in the file r.txt and displays in my terminal . What do i need to do if i want to save this existing file with this new record appended after the end of each line .

Do you mean that you want to save stdout to a file, or edit? Well, both approaches have been answered. — keyser, Jul 01 '14 at 20:21

To save to a new file:

sed 's/$/ foo/' r.txt > newfile.txt

To edit in place

sed -i 's/$/ foo/' r.txt
