How to do “du” on all files under a directory in linux?

Question

This is what I tried:

[demo@ ~]# ll /usr/local/apache2/logs/|xargs |du -hm -
du: cannot access `-': No such file or directory

I want to see the amount of space each file occupies in m unit.

How to do it the correct way?

Answer 1

I'm assuming ll is an alias for ls -l, in which case what's wrong with

du -hm /usr/local/apache2/logs/*

Answer 2

du -s /usr/local/apache2/logs/* | sort -rn | cut -f2 | xargs -d '\n' du -sh

Answer 3

Ok, not exactly what you asked for, but tree -fis or tree -fih might help you a bit and is a small, compact solution. :)

The first command outputs the recursive directory tree showing also the file size in bytes, the second one is the same but has "human readable" output, showing the size in kilobytes, megabytes, gigabytes... whatever it considers appropriate for that file.

Answer 4

Are you trying not to descend into subdirectories?

How about:

find . -type f -maxdepth 1 |xargs du -m 

Pipe to "sort -n" if desired.
