In a shell script, aforloop allows you to iterate over a set of values or a range of numbers. Here are a few examples of how to useforloops in different contexts: Example 1: Iterating Over a List of Values #!/bin/bash # List of values for item in apple banana cherry do echo "...
Once the shell script is executed, all the values in the range are listed, similar to what we had insimple loops. Bash For Loop with Ranges Example Additionally, we can include a value at the end of the range that is going to cause thefor loopto iterate through the values in incrementa...
If you don’t specify the keyword “in” followed by any list of values in the bash for loop, it will use the positional parameters (i.e the arguments that are passed to the shell script). $ cat for3.sh i=1 for day do echo "Weekday $((i++)) : $day" ...
The range is specified by a beginning (#1) and ending number (#5). The for loop executes a sequence of commands for each member in a list of items. A representative example in BASH is as follows to display welcome message 5 times with for loop: 代码语言:txt AI代码解释 #!/bin/bash ...
我们常常需要重复执行同一段代码,针对这种场景,Rust 提供了多种循环(loop)工具。一个循环会执行循环体中的代码直到结尾,并紧接着回到开头继续执行。 而Rust 提供了 3 种循环:loop、while 和 for,下面逐一讲解。 loop 循环 我们可以使用 loop 关键字来指示 Rust 反复执行某一段代码,直到我们显式地声明退出为止。
使用范围(Range)进行遍历 你还可以使用范围(Range)来遍历一系列数字。 foriin0..5{println!("Number: {}", i); } 使用闭包(Closure)进行遍历 你还可以使用闭包(Closure)作为循环体中的操作。 letnumbers= [1,2,3,4,5];fornumberinnumbers.iter().map(|x| x *2) {println!("Number: {}", number...
Parameters and Values for the Python range function ParametersValue start1 end20 step1 (default value) So, ourfor loopwill iterate through a sequence of numbers from 1 to 20, and for each iteration, it will print the number. The iteration stops when all the numbers in the sequence have be...
