# notify-send-all
Send a pop-up notification message to all users logged into a machine.
Similar to the `wall` command, but for graphical logins (X & Wayland).
Messages are sent asynchronously, not blocking, but `--action` can still be used to wait for a response from each user. Responses are prefixed with the username and a TAB.
## Installation
It's just a shell script. Download [notify-send-all](https://raw.githubusercontent.com/hackerb9/notify-send-all/main/notify-send-all), make it executable, and put it in your path. Or clone the repository, and add the working copy to your path.
```
wget raw.githubusercontent.com/hackerb9/notify-send-all/main/notify-send-all
chmod +x notify-send-all
sudo mv notify-send-all /usr/local/bin/
```
## Requirements
Users must be logged in graphically (X or Wayland) with dbus and a notification daemon running. This program does not yet work for users logged in on the console.
## Usage
**notify-send-all** _[options]_ \
### Simple usage
notify-send-all "My hovercraft is full of eels"
### More complex example
notify-send-all --urgency=critical \\
--action=run="Run away!" \\
--action=hide="Hide!" \\
"Warning: Nuclear launch imminent"

## Bugs
* `-?`, `--help` only works correctly if it is the first argument.
* If a user is logged in on a console instead of a graphical session
(X or Wayland), then `notify-send` hangs for a long time before
timing out on StartServiceByName for org.freedesktop.Notifications.
This seems to be a bug in libnotify-1.8.1.
This bug is also triggered when the user is logged in on both
console and graphical sessions and logged into the console first.
In that case, not only does notify-send hang, but notifications
will not show up at all in the graphical session.
## Bonus commands
### notify-send-to
If you make a symlink called `notify-send-to`, you can use it to send a pop up notification to a single user.
### notify-send-others
If you make a symlink called `notify-send-others`, you can use it to send a pop up notification to all users but yourself.
