bash脚本在锁定步骤中通过两个变量循环 [英] bash script loop through two variables in lock step

问题描述

我正在尝试编写一个循环遍历两个变量的bash脚本:

I'm trying to write a bash script that loops through two variables:

#!/bin/bash
for i in sd fd dir && j in storage file director
 do
   echo "restarting bacula $j daemon"
   /sbin/service bacula-$i restart
   echo
done

上面的代码显然是错误的.但我要我&j互相锁定.有人可以帮助我实现这一目标吗?

The code above is obviously wrong. But I want i & j to move in lock step with one another. Can someone help me with a way to achieve this?

谢谢

推荐答案

#!/bin/bash
a=(sd fd dir)
b=(storage file director)
for k in "${!a[@]}"
do
   echo "restarting bacula ${b[k]} daemon"
   /sbin/service "bacula-${a[k]}" restart
   echo
done
