tail follow file logrotate
On one of my servers I was running
tail -f /var/log/nginx/error.log. But output would stop every so often since the file is rotated with logrotate, giving that path a new inode number.
So when I switched to
tail -F, I no longer have to restart the
tail process to make it follow the output again.
-f --follow output appended data as the file grows -F same as --follow=name --retry --retry keep trying to open a file if it is inaccessible
