# logger
> Add messages to syslog.
- Log a message to syslog:
`logger {{message}}`
- Take input from stdin and log to syslog:
`tail -f {{app.log}} | logger`
- Send the output to a remote syslog server running at a given port. Default port is `syslog`:
`tail -f {{app.log}} | logger --server {{hostname}} --port {{port}}`
- Use a specific tag for every line logged. Default is the name of logged in user:
`tail -f {{app.log}} | logger --tag {{tag}}`
- Log messages with a given priority. Default is `user.notice`. See `man logger` for all priority options:
`tail -f {{app.log}} | logger --priority {{user.warning}}`
