[root@minimal boot]# pwd
/boot
[root@minimal boot]# ls / |xargs du -sh
du: cannot access `bin': No such file or directory
du: cannot access `boot': No such file or directory
du: cannot access `cgroup': No such file or directory
du: cannot access `dev': No such file or directory
du: cannot access `etc': No such file or directory
du: cannot access `home': No such file or directory
du: cannot access `lib': No such file or directory
13K lost+found
du: cannot access `media': No such file or directory
du: cannot access `mnt': No such file or directory
du: cannot access `opt': No such file or directory
du: cannot access `proc': No such file or directory
du: cannot access `root': No such file or directory

[root@minimal boot]# cd /
[root@minimal /]# ls |xargs du -sh
5.9M bin
28M boot
4.0K cgroup
480K dev
31M etc
20K home
100M lib
16K lost+found
102M media
64M mnt
2.8G opt
du: cannot access `proc/2533/task/2533/fd/4': No such file or directory
du: cannot access `proc/2533/task/2533/fdinfo/4': No such file or directory

0 proc
139M root
9.2M sbin
0 selinux
4.0K srv
0 sys
380K tmp
2.6G usr
116M var
ls与xargs配合使用时,ls只能显示当前的目录,所以要想显示根目录下的文件的大小,必须在根目录下配合使用ls与xargs命令
[root@minimal /]# ls |grep -v proc |xargs du -sh |sort -h
0 selinux
0 sys
4.0K cgroup
4.0K srv
16K lost+found
20K home
380K tmp
492K dev

9.2M sbin
28M boot
31M etc
64M mnt
100M lib
102M media
116M var
152M root
2.6G usr
2.8G opt
按大小和单一模式显示除proc目录以外的所有根目录下的文件
/proc
这个目录本身是一个『虚拟档案系统』!它放置的数据都是在内存当中, 例如系统核心、形成信息、接口设备的状态及网络状态等等。因为这个目录下的数据都是在内存当中, 所以本身不占任何硬盘空间!
[root@RedHat /]# ls -A |grep -v proc |xargs du -sh |sort -h

ls -A显示所有文件但不包括"."和"..";即当前目录和当前目录的父目录。
