NAME
       logger - add entries to the system log

SYNOPSIS
       logger  [  -t  tag ] [ -p priority ] [ -i ] [ -f filename ] [ 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.   Other-
       wise,  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
       -t tag      Mark each line added to the log with the specified tag.

       -p priority Enter the message with the specified priority.  The message
                   priority can be  specified  numerically,  or  as  a  facil-
                   ity.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.

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

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

       message     If  this  is unspecified, either the file indicated with -f
                   or the standard input is added to the log.

EXAMPLES
              logger System rebooted

       will log the message `System rebooted'  to  the  facility  at  priority
       notice  to  be  treated  by  syslogd  as other messages to the facility
       notice are.

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

       will read from the file /dev/idmc and will log each line in  that  file
       as a message with the tag `HOSTIDM' at priority notice to be treated by
       syslogd as other messages to the facility local0 are.
