OpenWrt: Finding Files Occupying the Largest Space

OpenWrt的find命令不支持-size +1M这种格式。所以我们如果想找分类出大于1M的文件，可以使用-size +1048576c来代替。
1048576是1MB的字节数，c表示计数的是字节。

find / -type f -size +1048576c -exec du -h {} \;    # 查找大于1M的文件

然后可以去删除不需要的文件，毕竟硬路由寸金寸土。

OpenWrt’s find command does not support the -size +1M format. Therefore, if we want to find files larger than 1MB, we can use -size +1048576c as a replacement.
1048576 is the byte count for 1MB, and c indicates counting in bytes.

find / -type f -size +1048576c -exec du -h {} \;    # Find files larger than 1MB

Then you can proceed to delete unnecessary files, as space is at a premium on hardware routers.
