Bash arrays allow you to store multiple values in a single variable. This is particularly useful when you need to group related data together. Let’s dive into the basics of creating and accessing elements in a Bash array of strings. Creating a Bash Array In Bash, you can create an array...
When to use double quotes with Bash Arrays? Array Operations How to iterate over a Bash Array? (loop) How to get the Key/Value pair of a Bash Array? (Obtain Keys or Indices) How to get a Bash Array size? (Array length) How to remove a key from a Bash Array or delete the full...
${array_name[N]} 与大多数其他编程语言一样,Bash Shell 中的数组从索引 0 开始。这意味着第一个元素的索引为 0,第二个元素的索引为 1,第 n 个元素的索引为n-1。 因此,如果你想打印 SUSE,你将使用: echo${distros[2]} Example of accessing array elements in bash shell ...

我们常用memset()函数来将数组中所有的元素都设置为指定的值,java中也有类似的Arrays.fill()函数,但是它不能直接用于初始化二维数组,我们需要为其加上一重循环。...比如说,把数组a中的元素全部设置为-1,可以写成一下形式: for(int i=0;i<sizeX;i++) Arrays.fill(a[i], -1); 发布者:全栈程序员栈长...
If you're used to a "standard" *NIX shell you may not be familiar with bash's array feature. Although not as powerful as similar constructs in the P languages (Perl, Python, and PHP) and others, they are often quite useful. Bash arrays have numbered indexes only, but they are spars...
In the next section, we’ll take a look at more complex uses of loops with arrays in Bash. Advanced Techniques: Bash Array Looping As you become more comfortable with Bash scripting, you’ll find that there are more complex scenarios where you need to loop through arrays. This might includ...

Example of accessing array elements in bash shell ${之后或}之前不能有任何空格。你不能像${ array[n] }那样使用它。 一次访问所有数组元素 假设你要打印数组的所有元素。 你可以一一使用echo ${array[n]}但这确实没有必要。有一个更好更简单的方法: ${array[*]} 这将为你提供所有数组元素。 Accessing...
