From inside a directory My_dir I get the content size with ls:
$ ls -sh
total 386M
94M Kammermusik_Nocturne_chnl1.wav 94M Kammermusik_Nocturne_chnl3.wav 11M Kammermusik_Nocturne_stereo-mix.mp3
94M Kammermusik_Nocturne_chnl2.wav 94M Kammermusik_Nocturne_chnl4.wav
with a total size of 386 Megabytes. Then I read the size of the whole directory from 1 directory-level before:
$ cd ..
$ ls -sh
total 16K
4,0K Dir1 4,0K Dir2 4,0K Dir3 4,0K My_dir
The size of My_dir is shown as only 4 Kilobytes?! What am I reading false, as the total file was reported as 386M!
