linux - Shell user prompt (Y/n) -


I just wanted to write a small scripts to copy some files for my NAS, so I have shell-scripting . I know that many command line tools on Linux use the following sim for the Yes / No input 

  Do you know Yuri [Y / N]   
 Where the letter indicates the standard verb which will be started by killing  . Which is good for quick use.  
 I also like to apply something like this, but I have some difficulty in caching the  Enter  key. This is what I have so far received:  
  read -p "Are you sure? [Y / N]" Reaction Case $ [yy] Response [EE] [SS] | [Yay] | [JJ] | [# Insert coding here et #]) echo files will be echoed;; *) Echo canceld echo echo ;; esac   
 Whatever I want I can add but it will not work with only  enter .   
 
 
 Here's a quick solution:  
  read -p "what Are you sure? [Yi] [Yi] [EE] [ss] | [or y] | [jj] | '') resonant files will echo; *) echo echo echo echo; >
