Show HN: Alert yourself after a long-running task in terminal

Here is it for fish, using the postexec event handler:

    function postexec_notify --arg cmd --on-event fish_postexec
      set -l s $pipestatus
      if test "$CMD_DURATION" -ge 25000 && ! string match -rq '(^man|\s--help)(\s|$)' $cmd
        if string match "$status" -qv 0 $s
          terminal-notifier -title $cmd -message 'Exited with '(string join '|' $s)' after '(math $CMD_DURATION / 1000)s
        else
          terminal-notifier -title $cmd -message 'Finished in '(math $CMD_DURATION / 1000)s
        end
      end
    end

As a bonus, this includes the command line in the notification.

I found that this can be somewhat annoying when reading man pages or interactive content though. To remedy this, I tried detecting whether the terminal is focused at the time of command completion, but it doesn't seem possible to get the terminal's pid from fish. The pid of the topmost application can be retrieved with:

    osascript -e 'tell application "System Events" to return unix id of (first process whose its frontmost is true)'

Personally I have a flask app deployed on heroku that posts a message to a Discord webhook just by visiting an url. So in my case when I use ssh to run long tasks I have at the end "curl https:// .herokuapp.com/?Finished" and as soon as that commands is executed I receive a message either at my phone or computer (through a channel in a personal discord server).

Probably is a bit of a 'hacky' way, and using different proprietary services (heroku and discord) but it works, does it fine, and it's free! (And it was also funny and quick to develop by myself).

The source code is on Github too! https://github.com/TrianguloY/ping

Ouch, thanks for noticing, should be public now.

I also made a similar service in the past for Heroku webhooks, to be notified with heroku apps status. Github already have one built-in. https://github.com/TrianguloY/webhook-discord

Webhooks are a really interesting feature!

I use `noti` for this:

`some_task && noti`

`noti some_task`

both work.

You can also use noti to watch a process id, in case you start a process but forget to append noti
