# NAME

logger — make entries in the system log

# SYNOPSIS

logger | [-cins] [-d SD] [-f file] [-m msgid] [-p pri] [-t tag] [message ...]

# DESCRIPTION

logger provides a shell command interface to the syslog(3) system log module.

Options:

-c
  Log to console (LOG_CONS).
-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 (LOG_PID).
-m msgid
  The MSGID used for the message.
-n
  Open log file immediately (LOG_NDELAY).
-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 (LOG_PERROR).
-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.
