Print Keys and Values To print the values of an associative array, use theechoorprintfcommand and reference all the array elements. For example: echo ${example_array[@]}Copy The at symbol (@) accesses all array
On the other hand, if you want to print all the values of an Associative array, use${my_array[@]}as shown here: echo "Values: ${my_array[@]}" To print values of themyarray, I used the below command: echo "Values: ${myarray[@]}" 5. Find the Length of the Associative Array...
The above Bash script successfully prints the associative array “my_associative” (both the keys and values) using length expressions ${!my_associative[@]} and ${my_associative[@]} respectively. 2. Print an Array in Bash Using the “declare -p” Command The declare -p command in Bash di...

Bash支持两种数组,一种是所谓索引数组(indexed array),通过下标0,1,2...(跟大多数编程语言一样,下标从零开始,想起了孙燕姿的歌《爱从零开始》~)访问其中的元素,第二种叫做关联数组(associative array),通过Key来访问Value,也就是所谓的键值对(或Map)。我们首先看一下数组的声明和定义(Bash手册中查找关键字...
