关于openwrt 编译后的清理工作

df 和 fdisk 不适用于查看某一目录的大小 但是对于查看文件系统的使用情况比较有用 这里我使用了另一个命令：

：du 

下面实际使用以下：

maclinux@maclinux-virtual-machine:~/openwrt$ sudo du -h --max-depth=0 openwrt/
[sudo] password for maclinux: 17G	openwrt/

–max-dppth表示目录的深度

妈的，17G，

首先在su下执行：

maclinux@maclinux-virtual-machine:~/openwrt/openwrt$ sudo make clean -j1 V=s
[sudo] password for maclinux: make[1]: Entering directory '/home/maclinux/openwrt/openwrt'rm -rf /home/maclinux/openwrt/openwrt/build_dir/target-i386_i486_musl-1.1.14 /home/maclinux/openwrt/openwrt/staging_dir/target-i386_i486_musl-1.1.14 /home/maclinux/openwrt/openwrt/bin/x86 /home/maclinux/openwrt/openwrt/logsmake[1]: Leaving directory '/home/maclinux/openwrt/openwrt'

然后：

maclinux@maclinux-virtual-machine:~/openwrt/openwrt$ sudo make dirclean -j1 V=s
make[1]: Entering directory '/home/maclinux/openwrt/openwrt'rm -rf /home/maclinux/openwrt/openwrt/build_dir/target-i386_i486_musl-1.1.14 /home/maclinux/openwrt/openwrt/staging_dir/target-i386_i486_musl-1.1.14 /home/maclinux/openwrt/openwrt/bin/x86 /home/maclinux/openwrt/openwrt/logsrm -rf /home/maclinux/openwrt/openwrt/staging_dir/host /home/maclinux/openwrt/openwrt/staging_dir/toolchain-i386_i486_gcc-5.3.0_musl-1.1.14 /home/maclinux/openwrt/openwrt/build_dir/host /home/maclinux/openwrt/openwrt/build_dir/toolchain-i386_i486_gcc-5.3.0_musl-1.1.14rm -rf /home/maclinux/openwrt/openwrt/tmpmake[1]: Leaving directory '/home/maclinux/openwrt/openwrt'

再然后：

maclinux@maclinux-virtual-machine:~/openwrt/openwrt$ sudo make distclean -j1 V=s
make[1]: Entering directory '/home/maclinux/openwrt/openwrt/scripts/config'rm -f *.o lxdialog/*.o zconf.tab.c lex.zconf.c zconf.hash.c conf mconfmake[1]: Leaving directory '/home/maclinux/openwrt/openwrt/scripts/config'

现在看一下：

maclinux@maclinux-virtual-machine:~/openwrt/openwrt$  sudo du -h --max-depth=0 ../openwrt/193M	../openwrt/

完成，当然，下载的包也没有了
