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.

./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/find3 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
pauseLinux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..."参考

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
#include
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\n");
else if (un.c[0] == 2 && un.c[1] == 1)
printf("little-endian\n");
else
printf("unknown\n");
} else
printf("sizeof(short)= %d\n",sizeof(short));
exit(0);
} busybox-mipsel在君正M200可用。
vi会乱码，用不了。
