In this example, we’ve created a ‘for’ loop that acts as a ‘foreach’ loop. The loop iterates over the numbers 1 through 5, echoing each number on a new line. This is a basic way to use the ‘foreach’ loop in Bash, but there’s much more to learn about looping and itera...
This tutorial explains using the for loop in Bash scripts by using the range notation and the three-expression notation like in the C programming language.
Bash For Loop In one line with Command Output # for i in `seq 1 5`;do echo $i ;done # for i in `cat test`;do dig $i +short ;done # for i in `awk '{print $1}' test` ;do ping -c 2 $i ;done Bash For Loop In one Line with variables # for i in $(cat test);do...

SSIS中Foreach Loop Container的使用--遍历结果集 在之前的文章中介绍过SSIS中变量的使用,其中用到result set这个东西,当时设置成了single row,那是我们只需要那一个数据,当我们需要多个数据的时候我们就需要将result set 设置为Full result set,先来个整体效果,再说明下:手机充值:http://yjck67.taobao.com,...
The Bash script provides two syntaxes for writing theforloops. The first one is known as C-style or three expression loop, and it is nearly the same as the C-language formulation for theforloop. The second formulation is a famousforeachorfor-instyle construct, also have been adopted by ...

Bash For Loop To Print Even Values In the range, the first value represents a starting point, the second represents the endpoint, and the third represents the skip point for each iteration. Here, the loop will skip every second iteration and will execute only for the even values. See the ...
在Bash For Loop中使用“Continue”语句 “ continue ”语句是控制脚本运行方式的内置命令。除了bash脚本之外,它还用于Python和Java等编程语言。continue语句在满足特定条件时停止循环内的当前迭代,然后恢复迭代。可以看看如下所示的for循环。 #!/bin/bash
在bash中,可以使用for循环来重复执行一系列命令。for循环的语法如下: ```bash for 变量名 in 值列表 do 命令 done ``` 其中,变量名是用来存储值列表中的每...
