如何在shell脚本中提供输入列表？

Question

我需要在Shell脚本中提供输入列表并读取它们并迭代并为每个文件夹执行'svn update'，如下所示：

    echo "Please give the list of folders to be updated:"
    read $list
    for name in ${list[@]} do
          svn update $name
    done

如何通过shell脚本实现此功能。

谢谢和问候，

Answer 1

如果您尝试将值读入数组，请使用：read -a

read -a list -p "Please give the list of folders to be updated: "

for name in "${list[@]}"; do
   svn update "$name"
done

否则就这样使用：

read -p "Please give the list of folders to be updated: " list

for name in $list; do
   svn update "$name"
done

但请记住，您的文件夹名称不应包含空格或换行符。

#!/bin/bash

echo "Please give the list of folders to be updated:"
read list $*
for name in "${list[@]}"; do
    svn update "${name}"
done
