A 'for loop' is a bash programming language statement which allows code to be repeatedly executed. A for loop is classified as an iteration statement i.e. it is the repetition of a process within a bash script. For example, you can run UNIX command or task 5 times or read and process...
在Bash脚本,有3种类型loops:for loop,while loop, 和until loop. 这三个用于迭代值列表并执行一组给定的命令。 Bash For 循环语法 for loop遍历一系列值并执行一组命令。 For loop采用以下语法: forvariable_name in value1 value2 value3..ndocommand1 command2 commandn done 1. 2. 3. 4. 5. 6. Ba...
bash shell脚本中同样支持仿C语言的for循环语法，bash支持类似C语言的for循环，使用变量表达式定义循环，其构造如下：for (( variable assignment; condition; iteration process ))do commandsdone 例如，以下是一个仿C语言风格的for循环示例，它同样会打印出数字1到10：#testing the C-style for loopfor ((i=1...

如前所述,for 循环遍历一系列值并执行一组 Linux 命令。 For 循环采用以下语法: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 forvariable_nameinvalue1 value2 value3..ndocommand1 command2 commandn done 现在让我们检查 bash for 循环的几个示例用法。
Example 1 - for Loop to Read Input Variable Using the for loop, it is straightforward to read the predefined strings or array. Here is an example of how you can use the for loop. In the example, we will take the input value of a text that has multiple words that will be taken afte...
Bash中的for循环是一种控制结构,用于重复执行一段代码块,直到满足特定条件。其基本语法如下: 代码语言:txt 复制 for variable in list do # 执行的命令或代码块 done 可能的原因及解决方法 如果for循环只执行了一次迭代,可能是由于以下几个原因: 列表为空:如果list为空,那么for循环将不会执行任何迭代。 列表为空...
First, let's talk about the basic structure of aforloop, and then we'll get into some examples. The basic syntax of aforloop is: for <variable name> in ;do <some command> $<variable name>;done; Thevariable namewill be the variable you specify in thedosection and will contain the ...
