make entries in the system
logger utility provides a shell
command interface to the
syslog(3) system log module.
The options are as follows:
- If unable to pass the message to syslogd(8), attempt to write the message to the console.
- Read from the specified file.
- Log the process ID of the logger process with each line.
- Enter the message with the specified priority. The priority may be specified numerically or as a “facility.level” pair. For example, “-p local3.info” logs the message(s) as informational level in the local3 facility. The default is “user.notice”.
- Log the message to standard error, as well as the system log.
- Mark every line in the log with the specified tag.
- Write the message to log; if not specified, and the
-fflag is not provided, standard input is logged.
logger utility exits 0 on
success, and >0 if an error occurs.
