上次的 issues 问题：#11603 经过不断尝试，发现问题原因在 `package/lean/autocore/files/x86/index.htm` 文件 该文件中获取 CPU 使用率所在行的命令 `top -n 1 | grep 'CPU:'` 会获取到两行数据，另一行是 `grep CPU` 进程自身，导致计算报错，如下所示 ``` root@OpenWrt:~# top -n 1 | grep 'CPU:' CPU: 0% usr 9% sys 0% nic 90% idle 0% io 0% irq 0% sirq 2813 6672 root S 1124 0% 0% grep CPU: ``` 由于 x86 平台和 arm 平台使用的是不同的 index.htm 文件，获取 CPU 使用率的命令也不一样，再结合其他人的反馈，所以这个问题应该是只出现在 x86 平台上 虽然我也还是不知道为啥在编译时取消 autosamba 就会出现这个问题，但是修改匹配条件使用 `grep -E '^CPU:' ` 匹配以 `CPU:` 开头的行可修复此问题 在编译前修改 `package/lean/autocore/files/x86/index.htm`，找到 `grep 'CPU:'` 修改为 `grep -E '^CPU:'` 即可

Q：你知道这是
pull request吗？(使用 "x" 选择)之前提过 issues #11603
经过不断尝试，发现在
package/lean/autocore/files/x86/index.htm文件中获取 CPU 使用率所在行的命令top -n 1 | grep 'CPU:'会获取到两行数据，而另一行是grep CPU:进程自身，最终导致 CPU 使用率计算报错，如下所示由于 x86 平台和 arm 平台使用的是不同的 index.htm 文件，获取 CPU 使用率的命令也不一样，再结合其他人的反馈，所以这个问题应该是只出现在 x86 平台上
虽然我也还是不知道为啥在编译时取消 autosamba 就会出现这个问题，但是修改匹配条件使用
grep -E '^CPU:'匹配以CPU:开头的行可修复此问题
