Usage Guidelines The type-tail command allows you to monitor a log file by letting you view the end of the file. You can
specify the number of lines at the end of the file that you want to view, or you can follow the last line of
the file as it continues to log new information. To stop the last line from continuously scrolling as with
the follow option, use the key sequence Ctrl-C.
You can further indicate the type of information to display using the output modifiers. These allow you
to include or exclude specific lines or to indicate where to begin displaying the file.
Examples The following example shows how to looks for a list of log files in the /local1 directory and then displays
the last ten lines of the syslog.txt file. In this example, the number of lines to display is not specified, so
the default of ten lines is used:
