<div data-language="zulip-send" markdown="1"> You can use `zulip-send`
(available after you `pip install zulip`) to easily send Zulips from
the command-line, providing the message content via STDIN.
#### Stream message
```bash
zulip-send --stream Denmark --subject Castle \
--user othello-bot@example.com --api-key a0b1c2d3e4f5a6b7c8d9e0f1a2b3c4d5
```
#### Private message
```bash
zulip-send hamlet@example.com \
--user othello-bot@example.com --api-key a0b1c2d3e4f5a6b7c8d9e0f1a2b3c4d5
```
#### Passing in the message on the command-line
If you'd like, you can also provide the message on the command-line with the `-m` flag, as follows:
```bash
zulip-send --stream Denmark --subject Castle \
-m "Something is rotten in the state of Denmark." \
--user othello-bot@example.com --api-key a0b1c2d3e4f5a6b7c8d9e0f1a2b3c4d5
```
You can omit the `user` and `api-key` arguments if you have a `~/.zuliprc` file.
