I discovered something interesting. Both of these run as a user without privileges on a RH7.3 + updates box: dd if=/dev/zero of=oink yes 'abcdabcd' > oink Other than the contents of the file being pushed to disk, these are the same essential thing, right?: fill the local disk partition up. Wrong. Thank you for playing. The first one *does* fill the disk. The second one hits a filesize limit. | magnitude spare:0:267} dd if=/dev/zero of=oink | dd: writing to `oink': No space left on device | 19052521+0 records in | 19052520+0 records out | magnitude spare:1:268} df . | Filesystem 1k-blocks Used Available Use% Mounted on | /dev/hda11 10080488 9568420 0 100% /mnt/spare | magnitude spare:0:269} ls | lost+found/ oink | magnitude spare:0:270} rm oink | magnitude spare:0:271} ls /dev/one | ls: /dev/one: No such file or directory | magnitude spare:1:272} yes 'abcdabcd' > oink | Filesize limit exceeded | magnitude spare:153:273} df . | Filesystem 1k-blocks Used Available Use% Mounted on | /dev/hda11 10080488 2132044 7436376 23% /mnt/spare After a bit more thought during typing the email, we have another dd running in the background and wala!: | magnitude spare:0:280} ls -l | total 7450844 | drwx------ 2 root root 16384 Mar 17 2002 lost+found/ | -rw-r--r-- 1 sinck sinck 2147483647 Jan 9 06:12 oink | -rw-r--r-- 1 sinck sinck 5474697728 Jan 9 06:28 oink2 So... a 2G file limit.
