本文介绍了如何将数组参数传递给Bash脚本的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

让我惊讶的是，在搜索1小时后我没有找到答案. 我想像这样将数组传递给我的脚本:

It is surprising me that I do not find the answer after 1 hour search for this. I would like to pass an array to my script like this:

test.sh argument1 array argument2

我不想将其放在另一个bash脚本中，如下所示:

I DO NOT want to put this in another bash script like following:

array=(a b c) for i in "${array[@]}" do test.sh argument1 $i argument2 done

推荐答案

Bash数组不是一流的值"-您不能像一个事物"那样传递它们.

Bash arrays are not "first class values" -- you can't pass them around like one "thing".

假设test.sh是一个bash脚本，我会做

Assuming test.sh is a bash script, I would do

#!/bin/bash arg1=$1; shift array=( "$@" ) last_idx=$(( ${#array[@]} - 1 )) arg2=${array[$last_idx]} unset array[$last_idx] echo "arg1=$arg1" echo "arg2=$arg2" echo "array contains:" printf "%s\n" "${array[@]}"

并像调用它一样

test.sh argument1 "${array[@]}" argument2
