变量:存储单个元素的内存空间数组:存储多个元素的连续的内存空间数组索引:编号从0开始,属于数值索引,索引也可支持使用自定义格式,而不仅仅是数值格式bash的数组支持稀疏格式数组常用操作:数组声明:普通数组:declare -a ARRAY_NAME关联数组:declare -A ARRAY_NAME数组元素赋值:一次只赋值一个元素:ARRAY_NAME[INDEX]=VALUE,
Bash arrayscan be referenced using the index number. Each element of the array can also be accessed using a loop. Furthermore, all the array elements can be accessed together in one go. Bash also gives the option to access the array elements from a particular element. Example: #!/bin/bas...

$ my_array=(one two three four five) $ last_element=${my_array[4]} $ echo "The 5th element is: "${last_element}"" The 5th element is: five Copy In this Bash code, we initialized a variable my_array with five elements. Next, we read the last element using index 4 (actually ...
An array is a variable containing multiple values may be of same type or of different type. There is no maximum limit to the size of an array, nor any requirement that member variables be indexed or assigned contiguously. Array index starts with zero. I

Use index to print values of array in bash This method uses a typical for loop where you declare the initial value, a condition, and if the condition is true then an action (increment or decrement). Here's a simple syntax to get the work done: ...
