SYNOPSIS

logger [-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:
 
 
-f file
Read from the specified file.
 
 
-i
Log the process ID of the logger process with each line.
 
 
-p pri
Enter the message with the specified priority. The priority may be specified numerically or as a “facility.level” pair. For example, “-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.

EXIT STATUS

The logger utility exits 0 on success, and >0 if an error occurs.

EXAMPLES

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