Пакет logtail: Информация

This program will read in a standard text file and create an offset
marker when it reads the end. The offset marker is read the next time
logtail is run and the text file pointer is moved to the offset
location. This allows logtail to read in the next lines of data
following the marker. This is good for marking log files for automatic
log file checkers to monitor system events.

This program is mainly used by logcheck, because it returns only parts
of the system logfiles that have not already been checked.
