Description: `Publish a message to a ntfy server.
Examples:
ntfy publish mytopic This is my message # Send simple message
ntfy send myserver.com/mytopic "This is my message" # Send message to different default host
ntfy pub -p high backups "Backups failed" # Send high priority message
ntfy pub --tags=warning,skull backups "Backups failed" # Add tags/emojis to message
ntfy pub --delay=10s delayed_topic Laterzz # Delay message by 10s
ntfy pub --at=8:30am delayed_topic Laterzz # Send message at 8:30am
ntfy pub -e phil@example.com alerts 'App is down!' # Also send email to phil@example.com
ntfy pub --click="https://reddit.com" redd 'New msg' # Opens Reddit when notification is clicked
ntfy pub --attach="http://some.tld/file.zip" files # Send ZIP archive from URL as attachment
ntfy pub --file=flower.jpg flowers 'Nice!' # Send image.jpg as attachment
ntfy pub -u phil:mypass secret Psst # Publish with username/password
NTFY_USER=phil:mypass ntfy pub secret Psst # Use env variables to set username/password
NTFY_TOPIC=mytopic ntfy pub -P "some message"" # Use NTFY_TOPIC variable as topic
cat flower.jpg | ntfy pub --file=- flowers 'Nice!' # Same as above, send image.jpg as attachment
ntfy trigger mywebhook # Sending without message, useful for webhooks
Please also check out the docs on publishing messages. Especially for the --tags and --delay options,
it has incredibly useful information: https://ntfy.sh/docs/publish/.
The default config file for all client commands is /etc/ntfy/client.yml (if root user),
or ~/.config/ntfy/client.yml for all other users.`,
