SYNOPSIS
logger

DESCRIPTION
logger provides a shell command interface to the syslog(3) system log module.
 
Options:
 
-d sd
Log this in the structured data (SD) field. (sd has to be passed as one argument and will require careful quoting when used from the shell.)
-f file
Log the specified file.
-i
Log the process id of the logger process with each line.
-m msgid
The MSGID used for the message.
-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.
EXIT STATUS
The logger utility exits 0 on success, and >0 if an error occurs.
EXAMPLES
logger System rebooted logger -p local0.notice -t HOSTIDM -f /dev/idmc
