/bin/bashfornin{1..7};doecho $n done 执行shell 脚本后,将列出范围内的所有值,类似于我们在简单循环中的情况。 此外,我们可以在范围的末尾包含一个值,该值将导致 for 循环以增量步骤迭代这些值。 以下bash 脚本打印 1 到 7 之间的值,从第一个值开始在这些值之间增加 2 个步长。 代码语言:javascript ...
# for i in `cat filelist.txt`; do echo ${i}; done; if a line may include spaces better use a while loop: # cat filelist.txt | while read LINE; do echo "${LINE}"; done 10 Bash for Loop In One Line Examples Bash For Loop Examples In Linux What Is Bash in Linux?
Shell scripting, specifically Bash scripting, is a great way to automate repetitive or tedious tasks on your systems. Why type when you can schedule and run scripts in a hands-free manner? One of the many scripting constructs is the loop. A loop is a section of code that picks up data ...
for 变量 in 列表 do command1 command2 ... commandN done 列表是一组值(数字、字符串等)组成的序列,每个值通过空格分隔。每循环一次,就将列表中的下一个值赋给变量。in 列表是可选的,如果不用它,for 循环使用命令行的位置参数。范例1顺序输出当前列表中的数字:#!/bin/bash for loop in 1 2 3 4 5...

在Linux / UNIX操作系统下,如何使用bash for loop重复执行某些任务? 如何使用for语句设置无限循环? 如何使用三参数进行循环控制表达式? “ for循环”是bash编程语言的语句,它允许重复执行代码。 for循环被归类为迭代语句,即bash脚本中进程的重复。 例如,您可以运行UNIX命令或任务5次,或使用for循环读取和处理文件列表。
在 Linux 中使用 Bash For 循环是一种高效执行重复性任务的方法。Bash 脚本提供三种类型的循环:for 循环、while 循环和 until 循环。在本篇指南中,我们将重点探讨如何使用 for 循环。For 循环用于遍历一系列值并执行一组给定的命令。其基本语法如下:bash for 变量 in 列表 do 命令 done 例如,遍历...
