Simulating ENTER keypress in bash script

Question

I ve created a really simple bash script that runs a few commands  one of these commands needs user input during runtime  i e it asks the user  do you want to blah blah blah    I want to simply send an enter keypress to this so that the script will be completely automated   I won t have to wait for the input or anything during runtime  its enough to just send the keypress and the input buffer will handle the rest

echo -ne   n     lt yourfinecommandhere gt    or taking advantage of the implicit newline that echo generates  thanks Marcin   echo    lt yourfinecommandhere gt    Now we can simply use the --sk option      --sk  --skip-keypress Don t wait for a keypress after each test   i e  sudo rkhunter --sk --checkall
