This loop will iterate 5 times, and each time, it will receive a value from the lists and store it in the variable named color that will print inside the loop. #!/bin/bash # Define loop to read string values for color in Blue Green Pink White Red do # Print the string value echo...
The most simple use of ‘for’loop is to read a list of string or numeric data. The list of numeric data is iterated by usingfor-inloop in the following example. Here, four numbers will be read in the variable,$nin each step of the loop and printed. Create a bash file with the f...
递归遍历如下:将已知路径和列表数组作为参数传递, public void Director(string dir,List list) { DirectoryInfo d...d.GetDirectories();//文件夹 foreach (FileInfo f in files) { list.Add(f.Name);//添加文件名到列表中...} //获取子文件夹内的文件列表,递归遍历 foreach (DirectoryInfo dd ...
You’re not alone. Many developers find themselves in a loop of confusion when it comes to using ‘foreach’ loops in Bash. But don’t worry, we’re here to help. Think of the ‘foreach’ loop as a skilled conductor, orchestrating your code to perform tasks repetitively and efficiently....
Before the first iteration, expr1 is evaluated. This is usually used to initialize variables for the loop. All the statements between do and done are executed repeatedly until the value of expr2 is TRUE. After each iteration of the loop, expr3 is evaluated. This is usually used to incremen...
for i in 1 2 3 4 5 do echo "Hy $i" done Once you execute the above set of instructions, the results you will get will be something like: Hy 1 Hy 2 Hy 3 Hy 4 Hy 5 #!/bin/bash– It verifies that the following code is a part of Bash coding. Now let’s break each element...
Instead of listing the for-in loop items, use an array to make your code more organized and easily readable. It simplifies iterating through data – the process of applying the loop for each item individually. Declare the array with its item at the beginning and add it to your for-in ex...
