linux 查看根卷文件大小

du -xh | awk '$1~/[0-9]G/  {print $0}' | sort -nk1

[hyb92@localhost ~]$ du -xh | awk '$1~/[0-9]M/ {print $0}' | sort -nk1

du -xh 

第一个首先获取根卷的全部相关文件夹大小

[hyb92@localhost ~]$ du -xh
4.0K ./Music
8.0K ./.dbus/session-bus
12K ./.dbus
8.0K ./.gconf/desktop/gnome/accessibility/keyboard
12K ./.gconf/desktop/gnome/accessibility
8.0K ./.gconf/desktop/gnome/peripherals/keyboard/host-bogon/0
12K ./.gconf/desktop/gnome/peripherals/keyboard/host-bogon
16K ./.gconf/desktop/gnome/peripherals/keyboard
20K ./.gconf/desktop/gnome/peripherals
36K ./.gconf/desktop/gnome
40K ./.gconf/desktop

awk '$1~/[0-9]G/  {print $0}' 

通过awk获取匹配的占用空间较大的文件夹信息

sort -nk1
