logger - add entries to the system log

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

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 unspecified, either the file indicated with -f or the standard input is added to the log. Otherwise, a file 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.

The following options are supported: -ffile

-i -ppriority -ttag

The following operand is supported: message

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.

See environ(7) for descriptions of the following environment variables that affect the execution of logger: LANG, LC_ALL, LC_CTYPE, LC_MESSAGES, and NLSPATH.

The following exit values are returned: 0

>0
