使用bash从数组中提取匹配字符串的最佳方法

array=("apple" "banana" "cherry" "date")
match="an"
for item in "${array[@]}"; do
    if [[ $item == *"$match"* ]]; then
        echo "$item"
    fi
done

array=("apple" "banana" "cherry" "date")
match="an"
printf '%s\n' "${array[@]}" | grep "$match"

array=("apple" "banana" "cherry" "date")
match="an"
for item in "${array[@]}"; do
    if [[ $item =~ $match ]]; then
        echo "$item"
    fi
done
