Fast forwards to the position where the last run ended, and then
copies only the new lines of that file to the standard output.
-
Dump the contents of /vol/www/ap-logs/access to
stdout and use position.dat to store the position of last
line read. If this is the first run or the file is smaller than
before, the whole file is printed.
-
$ ./ffcat.pl position.dat /vol/www/ap-logs/access
-
Pipe results to other programs:
-
$ ./ffcat.pl position.dat /vol/www/ap-logs/access | wc -l
