The UNIX 'tail' command with the -f option does this.
$ tail filename   <-- by default, the last 10 lines will be shown,
then tail exits.
$ tail -n20 filename  <-- the last 20 lines are shown, then tail exits
$ tail -f filename  <-- follow the end of the file

--from the manual:
-f, --follow[={name|descriptor}]
     output  appended data as the file grows;
     -f, --follow, and --follow=descriptor are equivalent

One of the benefits of Open Source (Free) Software is that the source code
can be studied, modified, and freely shared with the community.
