数组声明的shellscript不工作在计划cron工作？ [英] array declaration of shellscript doesnot work in scheduled cron job?

问题描述

我创建了一个名为script.sh的shell脚本，它读取数组元素并将其打印在终端上。脚本如下：

I have created a shell script named "script.sh" which reads an arrays elements and prints it on terminal. The script is as follows:

 arr=("hello" "world")
for i in ${arr[@]}
do
echo  $i;
done

它在终端执行时会产生期望的输出，即'Hello World'如果我在crontab作业中安排相同的脚本，每分钟自动执行并将输出存储在另一个文件中，则作业失败并提供

It gives expected output i.e 'Hello World' on executing it in terminal, but if I schedule the same script in crontab jobs to get executed automatically every minute and store the output in another file,the job fails and gives

home / vikash / script.sh：1：语法错误：（意外错误。

crontab作业每分钟执行一次脚本并将输出存储在另一个文件中如下：

The crontab job to execute the script every minute and store the output in another file is as follows:

* * * * * $HOME/script.sh >> $HOME/output.log 2>&1

如何在此场景中使用数组帮助。

How to use array in this scenario?? please help.

推荐答案

在脚本的第一行之前添加：

Add this before the first line of your script:

#!/bin/bash
