The logger command provides an interface to the syslog subroutine, which writes entries to the system log. A Message variable can be specified on the command line, which is logged immediately, or a File variable is read and each line of the File variable is logged. If you specify no flags or variables, the logger command will wait for you to enter a message from standard input.

-t Tag |
