Follow tail by name (fix for rolling logs with tail -f)

tail -F file
If you use 'tail -f foo.txt' and it becomes temporarily moved/deleted (ie: log rolls over) then tail will not pick up on the new foo.txt and simply waits with no output. 'tail -F' allows you to follow the file by it's name, rather than a descriptor. If foo.txt disappears, tail will wait until the filename appears again and then continues tailing.

What Others Think

I love this command. Don't forget you can follow more than one file at once: tail -F error_apache.log error_php.log error_trac.log error_svn.log
