I want to be able to have my program display an alert, notice, whatever that displays my custom text. How is this done? Also, is it possible to make one with several buttons that sets a variable?
Similar to batch's:
echo msgbox""<a.vbs&a.vbs
Use osascript. For example:
osascript -e 'tell app "Finder" to display dialog "Hello World"'
Replacing “Finder” with whatever app you desire. Note if that app is backgrounded, the dialog will appear in the background too. To always show in the foreground, use “System Events” as the app:
osascript -e 'tell app "System Events" to display dialog "Hello World"'
Read more on Mac OS X Hints.
If you're using any Mac OS X version which has Notification Center, you can use the terminal-notifier gem. First install it (you may need sudo):
gem install terminal-notifier
and then simply:
terminal-notifier -message "Hello, this is my message" -title "Message Title"
See also this OS X Daily post.
Use this command to trigger the notification center notification from the terminal.
osascript -e 'display notification "Lorem ipsum dolor sit amet" with title "Title"'
This would restore focus to the previous application and exit the script if the answer was empty.
a=$(osascript -e 'try
tell app "SystemUIServer"
set answer to text returned of (display dialog "" default answer "")
end
end
activate app (path to frontmost application as text)
answer' | tr '\r' ' ')
[[ -z "$a" ]] && exit
If you told System Events to display the dialog, there would be a small delay if it wasn't running before.
For documentation about display dialog, open the dictionary of Standard Additions in AppleScript Editor or see the AppleScript Language Guide.
And my 15 cent. A one liner for the mac terminal etc just set the MIN= to whatever and a message
MIN=15 && for i in $(seq $(($MIN*60)) -1 1); do echo "$i, "; sleep 1; done; echo -e "\n\nMac Finder should show a popup" afplay /System/Library/Sounds/Funk.aiff; osascript -e 'tell app "Finder" to display dialog "Look away. Rest your eyes"'
A bonus example for inspiration to combine more commands; this will put a mac put to standby sleep upon the message too :) the sudo login is needed then, a multiplication as the 60*2 for two hours goes aswell
sudo su
clear; echo "\n\nPreparing for a sleep when timers done \n"; MIN=60*2 && for i in $(seq $(($MIN*60)) -1 1); do printf "\r%02d:%02d:%02d" $((i/3600)) $(( (i/60)%60)) $((i%60)); sleep 1; done; echo "\n\n Time to sleep zzZZ"; afplay /System/Library/Sounds/Funk.aiff; osascript -e 'tell app "Finder" to display dialog "Time to sleep zzZZ"'; shutdown -h +1 -s
A simular question and answer is available at: https://superuser.com/questions/246353/how-to-make-the-terminal-do-a-pop-up-alert-in-osx
I made a script to solve this which is here. You don't need any extra software for this.
Installation:brew install akashaggarwal7/tools/tsay
Usage:sleep 5; tsay
