NAME

logger − add entries to the system log

SYNOPSIS

/usr/ucb/logger [ −i ] [ −f filename ] [ −p priority ] [ −t tag ] [ message ] ...

DESCRIPTION

logger provides a method for adding one-line entries to the system log file from the command line.  One or more message arguments can be given on the command line, in which case each is logged immediately.  If this is unspecified, either the file indicated with −f or the standard input is added to the log.  Otherwise, a filename can be specified, in which case each line in the file is logged.  If neither is specified, logger reads and logs messages on a line-by-line basis from the standard input. 

OPTIONS

−i Log the process ID of the logger process with each line. 

−f filename Use the contents of filename as the message to log. 

−p priority Enter the message with the specified priority. The message priority can be specified numerically, or as a facility.level pair.  For example, ‘−p local3.info’ assigns the message priority to the info level in the local3 facility.  The default priority is user.notice. 

−t tag Mark each line added to the log with the specified tag.

EXAMPLES

The following example:

example% logger System rebooted

logs the message ‘System rebooted’ to the default priority level notice to be treated by syslogd as are other messages to the facility user. 

The next example:

logger −p local0.notice −t HOSTIDM −f /dev/idmc

reads from the file /dev/idmc and logs each line in that file as a message with the tag ‘HOSTIDM’ at priority level notice to be treated by syslogd as are other messages to the facility local0.
