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.)

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.
