The
logger utility provides a shell command interface to
the
syslog(3) system log module.
The options are as follows:
-c- If unable to pass the message to
syslogd(8), attempt to write the
message to the console.
-f
file- Read from the specified file.
-i- Log the process ID of the logger process with each line.
-p
pri- 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”.
-s- Log the message to standard error, as well as the system log.
-t
tag- Mark every line in the log with the specified
tag.
- message
- Write the message to log; if not specified, and the
-f flag is not provided, standard input is
logged.
The logger utility exits 0 on success,
and >0 if an error occurs.
$ logger System rebooted
$ logger -p local0.notice -t HOSTIDM -f /dev/idmc
The logger utility is compliant with the
IEEE Std 1003.1-2008 (“POSIX.1”)
specification.
The flags [-cfipst] are extensions to that
specification.
