Mac bash 调用系统对话框

Show error message:

#!/usr/bin/env bash

# error "Message"
function error() {
  osascript <<EOT
    tell app "System Events"
      display dialog "$1" buttons {"OK"} default button 1 with icon caution with title "$(basename $0)"
      return -- Suppress result
    end tell
EOT

error "Not enough cheese!"

(You can use 

note

 or 

stop

 instead
of 

caution

 to show a different icon.)

#!/usr/bin/env bash

# prompt "Question" "Default value"
function prompt() {
osascript <<EOT
tell app "System Events"
text returned of (display dialog "$1" default answer "$2" buttons {"OK"} default button 1 with title "$(basename $0)")
end tell
EOT
}

value="$(prompt 'Enter:' '42')"
