NAME
     logger - add entries to the system log

SYNOPSIS
     logger [-i] [-f file] [-p priority] [-t tag] [message] ...


DESCRIPTION
     The logger command 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 unspeci-
     fied, either the file indicated  with  -f  or  the  standard
     input  is added to the log.  Otherwise, a file can be speci-
     fied, in which case each line in the file is logged. If nei-
     ther  is  specified,  logger  reads  and  logs messages on a
     line-by-line basis from the standard input.

OPTIONS
     The following options are supported:

     -ffile        Uses the contents of file as  the  message  to
                   log.


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


     -ppriority    Enters the message with the  specified  prior-
                   ity.  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.


     -ttag         Marks each line added  to  the  log  with  the
                   specified tag.


OPERANDS
     The following operand is supported:

     message    One of the string arguments  whose  contents  are
                concatenated  together,  in  the order specified,
                separated by single space characters.

     Example 1 Examples of the logger command


     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:


       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.
