logger - add entries to the system log SYNOPSIS
/usr/ucb/logger [-f filename] [-i] [-p priority] [-t tag] mm [message]... DESCRIPTION
The logger utility provides a method for adding one-line entries to the system log file from the command line. One or more message argu- ments can be given on the command line, in which case each is logged immediately. If message 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
The following options are supported: -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' assigns the message priority to the info level in the local3 facility. The default pri- ority is user.notice. -t tag Mark each line added to the log with the specified tag. EXAMPLES
Example 1 Logging a message The command: example% 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. Example 2 Logging messages from a file The command: example% 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.
