logger(1)

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  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.

     -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  con-
           catenated  together, in the order specified, separated
           by single space characters.

EXAMPLES

     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.
