Automating “enter” keypresses for bash script generating ssh keys

Question

I would like to create script, which simply runs ssh-keygen -t rsa. But how to pass to it 3 times enter?

Answer 1

a version with passphrase is:

$ ssh-keygen -t rsa -b 4096 -C "comment" -P "examplePassphrase" -f "desired pathAndName" -q 

• the -q is for silent
