MultiTail
lets you view one or multiple files like the original tail program. The
difference is that it creates multiple windows on your console (with
ncurses). It can also monitor wildcards: if another file matching the
wildcard has a more recent modification date, it will automatically
switch to that file. That way you can, for example, monitor a complete
directory of files. Merging of two or even more log files is possible.
