It was new for me to know about sparse files
http://www.gnu.org/manual/tar/html_node/tar_121.html
Simple commands to get real information:
du
ls -ls
only GNU-command(cp tar) can deal with such files correctly
But I want to convert sparse file to normal
But it seems to me that I only can rm it
Simple way to create sparse file:
dd if=/dev/zero of=/srv/ftp/1tbfile bs=1k count=1 seek=$((1024*1024*1024))
#ls -l bad
