If I use "df /dev/sda1 -h", it only shows the whole usage info like used and avail. But I want to see the usage of each directory. However, if I do "du -h --max-depth=1", it shows all the directories under "/" but some of them are not related to "/dev/sda1". Is there a way to combine the two, as titled? Thanks.
To clarify from the answers provided,
$ cd / $ sudo du --max-depth=1 -x -h 3.6G ./tmp 4.0K ./private 310M ./opt 4.0K ./crl 3.4M ./lib32 2.6G ./usr 0 ./dev 8.0K ./db 8.0K ./mnt 11M ./root 0 ./sys 16K ./lost+found 4.0K ./certs 8.7M ./bin 0 ./run 4.0K ./selinux 4.0K ./srv 7.7M ./etc 0 ./proc 385M ./lib 718M ./home 4.0K ./ctel 4.0K ./lib64 8.1M ./sbin 1.2G ./var 4.0K ./boot 8.0K ./media
Among them, "/ctel" and "/boot" are mounted on another partition, which I don't want to see. Thanks.
