notification on command completion (fish shell)

fish_noti.md

Instead of waiting for long commands to finish one can easily get notifications when they are complete. The following procdure shows how to set his in fish shell.

Requirements: fish shell, notify-send, xdotool

• Add a new file vi ~/.config/fish/functions/noti.fish with the content below:

function fish_right_prompt
    if test $CMD_DURATION
        # Check if terminal window is hidden
        if test (xdotool getactivewindow) -ne $WINDOWID
            # Show notification if dration is more than 30 seconds
            if test $CMD_DURATION -gt 30000
                # Show duration of the last command in seconds
                set duration (echo "$CMD_DURATION 1000" | awk '{printf "%.3fs", $1 / $2}')
                notify-send (echo (history | head -1) returned $status after $duration)
            end
        end
    end
end

• Add the following line at the end of ~/.config/fish/config.fish to source noti.fish:

. ~/.config/fish/functions/noti.fish

Thanks for the gist. I created (Telert) to easily configure sound alerts, desktop popup, or even Telegram/Slack/Teams/Discord messages when a long-running command finishes. It also works in Python commands.

Setting it up is quick and easy

pip install telert
telert config audio --set-default  # for sound
telert config desktop --set-default  # for popup
telert config telegram --token "<token>" --chat-id "<chat-id>" --set-default # for telegram

You can then use it with your long running commands in your script.

long_running_command | telert # Option 1
telert run long_running_Command # Option 2

Telert will time the command and send a notification to the provider channel when it completes with the execution time and exit code.
