root@xxx:/ # busybox
BusyBox v1.31.0 (2019-06-10 15:54:51 CEST) multi-call binary.
BusyBox is copyrighted by many authors between 1998-2015.
Licensed under GPLv2. See source distribution for detailed
copyright notices.

Usage: busybox [function [arguments]...]
   or: busybox --list[-full]
   or: busybox --show SCRIPT
   or: busybox --install [-s] [DIR]
   or: function [arguments]...

        BusyBox is a multi-call binary that combines many common Unix
        utilities into a single executable.  Most people will create a
        link to busybox for each function they wish to use and BusyBox
        will act like whatever it was invoked as.

使用find命令

root@xxx:/ # busybox find -name version
./sys/devices/platform/gpio-keys/input/input1/id/version
./sys/devices/platform/jz-i2c.2/i2c-2/2-0046/input/input0/id/version
./sys/module/bcm_pm_core/version
./sys/module/bt_power_bluesleep/version
./sys/module/jz_vpu_v12/version
./sys/module/jz_efuse_v12/version
./sys/module/ppp_mppe/version
./sys/module/GobiUSBNet/version
./sys/module/g_android/version
./sys/module/uinput/version
./sys/module/tda18271/version
./sys/module/jzmmc_v12/version
./sys/module/tcp_cubic/version
./proc/version
./proc/sys/kernel/version

链接快捷方式，命令前不用加busybox

ln -s /system/bin/busybox /system/bin/find

3 写脚本方便push到新设备

win10新建文件push_busybox_mipsel.bat

adb remount
adb push busybox-mipsel system/bin/busybox
adb shell chmod 777 system/bin/busybox
pause

Linux新建文件push_busybox_mipsel.sh

# !/bin/sh
adb remount
adb push busybox-mipsel system/bin/busybox
adb shell chmod 777 system/bin/busybox

if [ $? -eq 0 ]; then
    echo "succeed"
else
    echo "failed"
fi

read -n 1 -p "Press any key to continue..."

19.11.27

直接下载busybox-x86_64，在win10，运行报错。

下载busybox-mips，放到MIPS设备，Android系统，还是运行不了。报错

sh: /system/bin/busybox: not executable: magic 7F45

下载busybox-x86_64到Ubuntu虚拟机可以运行。

怎么查看设备是什么架构？

cat /proc/cpuinfo 

mips 是32位大端字节序

mipsel 是32位小端字节序

mips64el 是64位小端字节序

怎么查看机器大端小端？

#include <stdlib.h>
#include <stdio.h>
int main(int argc, char **argv)
{
    union {
        short s;
        char c[sizeof(short)];
    } un;
    un.s = 0x0102;
    if(sizeof(short)==2) {
        if(un.c[0]==1 && un.c[1] == 2)
            printf("big-endian
");
        else if (un.c[0] == 2 && un.c[1] == 1)
            printf("little-endian
");
        else
            printf("unknown
");
    } else
        printf("sizeof(short)= %d
",sizeof(short));
    exit(0);
}

busybox-mipsel在君正M200可用。

vi会乱码，用不了。
