I get some large files in 'ls -al', but when I 'measure' them with 'du', the size is much small. Example: (17:13) bgd@(bgd)[~/temp] ls -alsh my_file 19120 -rw-r--r-- 1 root bgd 763M Jul 29 16:56 my_file (17:13) bgd@(bgd)[~/temp] du -sh my_file 19M my_file So the 'ls -alsh' shows a file in size of 763M, but 19M of sectors are really 'occupied'. Can someone explain, please? Thanks, bogdan
