LOGGER(1) BSD Reference Manual LOGGER(1)NAMElogger - make entries in the system log
SYNOPSISlogger [-is] [-f file] [-p pri] [-t tag] [message ...]
DESCRIPTION
The logger utility provides a shell command interface to the syslog(3)
system log module.
The options are as follows:
-i Log the process ID of the logger process with each line.
-f file Log the specified file.
-p pri Enter the message with the specified priority. The priority may
be specified numerically or as a "facility.level" pair. For ex-
ample, "-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 or >0 if an error occurred.
EXAMPLES
$ logger System rebooted
$ logger-p local0.notice -t HOSTIDM -f /dev/idmc
SEE ALSOsyslog(3), syslogd(8)STANDARDS
The logger utility conforms to IEEE Std 1003.2-1992 ("POSIX.2").
CAVEATS
Starting with MirOS #10, the logger utility splits the data to log into
chunks of 512 bytes each, so that further truncation does not occur un-
less most of the input octets are vis(3) expanded, i.e. non-printable.
