thank u for the response. Im actually taking an exam and with instructors permission, I am looking for answers. It seems that this may be a trick question?
There's is actually one thing IS wrong. The size. The item in the list is a directory, and a directory has a fixed size structure and does not contain actuals files but only file names and references to i-node where file is located. You have only 3 reference links in your listing, thereby your directory uses only one normative block for itself and it cannot be that big as 8K as you see in a listing. You can try create directory and make files as large as you wish in it but it will not increase the file-size. The number of files kept in a directory increases amount of data associated with a directory and will increase the size on one. As I said there are only 3 hard links to your directory so there's no chance it may be 8k large. If you have questions like that take "UNIX Essentials and UNIX Core"DVD course it is widely available and all this stuff is explained there.
What is written in the post above this is incorrect. In Unix directories are not of a fixed size, they can grow but never shrink. Here's an example from one of my systems:
drwxrwxr-x 2 reborg reborg 28672 Mar 20 08:01 test
As you can see there are only two hard links, or in other words no subdirectories of test. How is this possible? Simple...there were directories there but they have been deleted, the directory is in fact empty.
Also the size varies also varies based on the number of contained files, after all a directory is a file, but I include this for completeness...
Code:
[reborg@www ~]$ mkdir test
[reborg@www ~]$ ls -lrt
drwxrwxr-x 2 reborg reborg 4096 Mar 20 08:08 test
[reborg@www ~]$ for (( i=0; i<1000; i++ )) { touch test/foo$i; }
[reborg@www ~]$ ls -lrt
drwxrwxr-x 2 reborg reborg 28672 Mar 20 08:06 test
Also please refrain from advertising the DVD course you have mentioned in almost all of your replies. There is a section in these forums dealing with learning resources, if you have another resource to suggest you can contact one of the moderators or admins and get it added to that section.
I'm sorry but it is RIGHT, You examples shows my point presizely, the directory "size" grows as you created 1001 files there but the directory's structure is independed of the size of the files you created but only of number of them. You can make each file 1k or 1T it will not change the size of the directory.
I do not advertize the DVD I recommend it since I'm learning from it myself.
