Deleting Files and Clearing Diskspace
Hi,

On our servers I have been removing files to clear up some diskspace.

If I do an ls -ltr command I can see a folder with quite a lot of data in it.

When I've gone into this folder and cleared it up, I go back to the previous directory and do another ls -ltr command and the filesize hasn't changed.

For example..

In my /var folder
Code:
drwx------   5 root     root        8192 Jan  9  2004 lost+found
drwxr-xr-x   2 root     bin          512 Jan  9  2004 nfs

drwxrwxrwx   8 root     sys      1193472 Dec 15 11:30 tmp

The tmp folder has quite a large filesize.

When I go into tmp I can see the following
Code:

The total of all the filesizes adds up to 333388 and not 1193472 as the directory appears to be in the /var folder.

Can any explain what is happening?

You're looking at the directory file, not at the size of the files under that directory.
You could use a different command:

HTML Code:
bash-2.03$ ls -ld /tmp
drwxrwxrwt  22 root     sys         7250 Dec 15 12:30 /tmp
bash-2.03$ du -ks /tmp
382912  /tmp
