Bash脚本- unix -未找到命令

I am new to bash script and I wonder why I recieve the above message. I try to an arithmetic value which comes from the for loop and then I would like to print the array. Can anyone help me?

我对bash脚本不熟悉，我想知道为什么我收到上面的消息。我尝试一个算术值，它来自于for循环，然后我想打印数组。谁能帮我吗?

Thank you in advance!!

提前谢谢你! !

#!/bin/bash
declare -a SCORES
for j in `seq 0 5`;
do
SCORES$j="$(sh myscript.sh $DSLAM $j | grep "" -c )"
done
for k in "${SCORES[@]}"
do
    echo "message $'\t' $SCORES$k"
done
echo ${#SCORES}

You cannot assign variable with name, which is generated at run time; at least not the way you are trying.

不能分配带有名称的变量，该变量在运行时生成;至少不是你尝试的方式。

You have below options:

你有以下选择:

declare "SCORES$j=$(sh myscript.sh $DSLAM $j | grep '' -c )" # creates new variables like SCORES1, SCORES2 etc.

eval "SCORES$j=$(sh myscript.sh $DSLAM $j | grep '' -c )" #Definitely not preferred.

SCORES[$j]="$(sh myscript.sh $DSLAM $j | grep '' -c )" #uses array you have created.

Most likely, option 3 is what you want.

最可能的情况是，选项3是您想要的。
