使用数组可以简化函数的传参,可以通过数组的索引来访问参数。
function fun_name(){
local args=("$@")
echo ${args[*]}
local lable_1=${args[0]}
echo ${lable_1}
}
fun_name "$@"
function main(){
fun_name;
}
main();或者main $@
~~~
$#:所有参数的个数
~~~

查看CPU架构:
lscpu | egrep 'x86_64|arrch64'
或者lscpu | grep -i 'Architectures'
x86_64为Intel 64或者amd64的CPU
aarch64为arm架构的CPU
