yes
Ever tried to replace a bunch of files with cp -rf some/destination . in linux?
Then you might have had to do a number ‘y’ to confirm the replacement of the already existing files, pretty annoying. Well linux has this marvelous little tool called yes, which automate this process and adds a y after the prompt when replacing a file.
if you just try to type yes in your console you will see that it starts printing ‘y’.
so this is how you actually do it:
yes cp -r some/directory/* .
For more information type man yes in your concole.
