I know these folders each have >80gb of files. Yet, they only show 4.0K in ls -lah? How can I have ls show size including the contents?

[root@aapsan01 aapxen01]# ls -lah
total 48K
drwxrwxrwx  6 root root 4.0K Sep 29 03:45 .
drwxrwxrwx 15 root root 4.0K Sep 27 09:15 ..
drwxr-xr-x  2 root root 4.0K Sep 29 03:45 aapxen01.0
drwxr-xr-x  2 root root 4.0K Sep 28 12:10 aapxen01.1
drwxr-xr-x  2 root root 4.0K Sep 27 09:21 aapxen01.2
drwxr-xr-x  2 root root 4.0K Sep 27 09:21 aapxen01.3

du --max-depth=1 -h should show how much space the folders use

That's what I want. Thanks. Too bad they couldn't make an ls switch to provide this info. O well. –  Flotsam N. Jetsam Sep 29 '10 at 13:39
    
I find that one pretty handy, so usually have it as an alias on my system like du-dir or something like that. –  dtlussier Sep 29 '10 at 14:26

Actually adding --max-depth=1 is kind of weird choice, because then sub-subfolders (and files inside those) are not counted at all. From question it's not clear whether that was wanted or not. –  Olli Mar 15 '11 at 17:46
    
@Olli Subfolders are counted, but not displayed. –  Bernhard Nov 15 '12 at 6:57
    
Also equivalent to du -d 1 -h –  checksum Nov 26 '13 at 8:02

Using the command du:

du -sh .

Note that this takes some time, because it has to scan the directory contents.

du -sh

where s displays a summary of the directory size.
h human readable format

Example:

[root@smsc tmp]# du -sh
219M    .

ls shows the size of the directory entry, not of the directory contents. The directory itself is basically a list of all file names contained in the directory, and thus quite small.

For getting the combined size of a directory and its contents, use du.

To show the size of /var, use:

du -sh /var

To show the size of contents of /var, use:

du -sh /var/*
