Quite often I run some job on the command line that takes a few minutes. Staring at the terminal waiting for the job to finish is not fun.Switching to check what's on Facebook I end up wasting an hour looking at pictures of cats and dogs. If I am lucky.
I am trying something new now. I'm trying to send myself an alert whenever a task is done. For this to work first I had to find a way tosend a notification from the command line.

AppleScript is a scripting language created by Apple. It has a bunch of commands. There are a couple of interesting ones, for example: display and say.
display
The display command can send a notification to the standard notification system of Mac that will show a pop-up for a few seconds and that can be listed by clicking on the hamburger icon in the top-right corner of the screen (at the right end of the menu bar).
We could write an AppleScript in a file and use osascript to run the file, but osascript can also execute one-liners where all the commands are on the command-line.That seems to be more useful at this point.
display hello world
The AppleScript code to send a notification with the text 'hello world!' looks like this:
In order to run it on the command line we need to wrap that code in single-quotes and use the -e flag of osascript.
Conversely, on-premise software is hosted on the user’s servers, and additional fees typically apply for updates, maintenance and so on. Small business software for mac.
The result is a pop-up like this that shows up in the top right corner of the screen and disappears after about 3 seconds:
You can open the Notification center (the hamburger icon in the top right corner of the screen) that will look something like this: (assuming the only notificationyou have is the one we just sent.) Project management app mac os x.
You can clear the list of notifications by clicking on the x.

display notification with title
The default title of the notification was 'Script Editor'. We can also set it in the AppleScript command:
and with osascript:
The result is better:
display notification with subtitle
If we have a title we can also have a subtitle:
The AppleScript command:
With osascript:
This is how the result looks like:
display notification and make sound
In addition to the visual notification, the display command can also include a sound effect.The sound can be one of the files in /System/Library/Sounds or in ~/Library/Sounds.
The AppleScript command:
executed by osascript:
If the name of the sound is incorrect Mac will make an alert sound.
Longer text
If we try to send a longer text:
The pop-up notification will only display the beginning:
but we can see the full text in the notification center:
display alert with confirmation request
There is another way to create a notification using the display alert command. The syntax is a bit different.The string that comes immediately after the display alert is the title and then one can optionally add a messageparameter with a longer explanation.

The osascript wrapped command:
Mac Command Line Open File
The result is a pop-up window in the middle of the screen that also stays there till you click on the OK button.
The alert won't be recorded in the notification center of your Mac.
Saying Hello World
Finally there is also the say command that can vocalize any text you give to it.
The AppleScript command:
wrapped in osascript on the command line:
This does not have any visual effect, but it is quite surprising when your computer starts to talk to you.
Execute after the long-running program
The whole article was written because I wanted to get some alert after a long-running program ends.Here we substitute the long-running program with sleep 2. We can then include a call toosascript or even two calls to osascript to be executed immediately after themain command (the sleep 2) ends.
I put in two ways of notification so I'll hear some text if I am near the computer but does not watch the screenand I'll get a pop-up that remains on the screen later. So even if I am out of the room when the process ends,I'll see the pop-up when I return to my computer.
