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 as a fallback (
LOG_CONS): if the message cannot be passed to syslogd(8), the message is written to /dev/console. -dsd- 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.)
-ffile- Log the specified file.
-i- Log the process id of the logger process with each line
(
LOG_PID). -mmsgid- The MSGID used for the message.
-n- Open log file immediately (
LOG_NDELAY). -ppri- 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). -ttag- Mark every line in the log with the specified tag.
- message
- Write the message to log; if not specified, and the
-fflag is not provided, standard input is logged.
EXIT STATUS
The logger utility exits 0 on
success, and >0 if an error occurs.
