Bash：循环遍历字符串数组后无法读出带空格的字符串

循环遍历字符串数组时处理带空格字符串的技巧

bash
#!/bin/bash
# 定义包含空格的字符串数组
my_array=("Hello World" "Bash Scripting" "String with Space")
# 使用双引号遍历数组
for element in "${my_array[@]}"; do
    echo "$element"
done

bash
#!/bin/bash
# 定义包含空格的字符串数组
my_array=("Hello World" "Bash Scripting" "String with Space")
# 保存旧的IFS值
oldIFS=$IFS
IFS=$'%
'
# 遍历数组
for element in ${my_array[@]}; do
    echo "$element"
done
# 恢复IFS为旧值
IFS=$oldIFS
