list sub-directories and disk space consumed

hugheskc@yahoo.com · 05-17-2013, 05:38 PM

I need a script that will start with the PWD and list sub-directories and the total amount of disk space consumed by all files in all directories under each sub directory.

bytes directory
----- ------------------
800m app
2200m product
350000m admin
456000m diag

Thank you for your help (:^)

This is not in the format you are asking for, but it's a start:

Code:

#!/bin/bash
find . -maxdepth 1 -mindepth 1 -type d | while read -r file
do
du -sh "$file"
done

In a certain directory at my end, this is the output:

Code:

1.9G    ./Documents
2.0G    ./Pictures
36G     ./Music
1.3G    ./from segundo
68M     ./downloads

The find and du commands have various other options that might be useful to you.

This could be done simply using commands.

To check size of all directories residing in pwd:

Code:

~$ du -sk ./*

To check size of all directories, including files, residing in pwd:

Code:

~$ find . -exec du -sk {} \;

These do not work the same. The first command shows the size of files as well as directories. The second command shows all that, plus the size of each subdirectory, and each file present in subdirectories.

However I thank you for reminding me of -exec. I guess I am still a newbie.

Code:

find . -maxdepth 1 -mindepth 1 -type d -exec du -sh {} \;

and upon further consideration, I see that this shows only directories:

Code:

du -sh */

Please re-read my post. First command will show sizes of all subdirectories only whereas second one will give sizes of all subdirectories as well as files.

Sorry, but that is not true. If there are files present in the current directory these will be shown. It also only shows one level deep.

Code:

$ ls -l
drwxr-x--- 6 druuna druuna  4096 jan 13 12:30 Fife
drwxr-x--- 8 druuna druuna  4096 mei  7 15:43 LFS
drwxr-x--- 2 druuna druuna  4096 jan 13 16:11 Log
drwxr-x--- 2 druuna druuna 69632 mei 11 10:03 Tmp
-rw-r----- 1 druuna druuna   102 mei 18 08:23 awk_script
-rw-r----- 1 druuna druuna    45 mei 18 08:20 file1
-rw-r----- 1 druuna druuna    45 mei 18 08:20 file2
-rw-r----- 1 druuna druuna    42 mei 18 08:20 file3

$ du -sk ./*
24      ./Fife
313992  ./LFS
8       ./Log
68      ./Tmp
4       ./awk_script
4       ./file1
4       ./file2
4       ./file3

To show all the subdirectories and not just one level the s switch needs to be removed, that combined with Beryllos' answer you get this:

Code:

$ du -k */
4       Fife/exile/Blaat
8       Fife/exile
4       Fife/192.168.100.11
4       Fife/10.0.100.11
4       Fife/stasis
24      Fife/
4       LFS/chapter7
4       LFS/chapter8
4       LFS/config
4       LFS/chapter6
4       LFS/chapter5
4       LFS/chapter4
313992  LFS/
8       Log/
68      Tmp/
