Example 5: C-style for Loop #!/bin/zshfor((i=1;i<=5;i++))doecho"Number:$i"done Practical Example: Creating Backup Files Create the script file backup.sh: nano backup.sh Add the following content: #!/bin/zshsource_dir="/path/to/source_directory"backup_dir="/path/to/backup_direct...
The code runs the “echo” statement 10 times with its iteration number as expected. $bashbash.sh Example 04: Another unique way to define the “for” loop is using the “seq” expression in it. So, open the same file and add the bash extension to it. The syntax of the “for” lo...
让我们使用for循环打印从 1 到 10 的数字: #!/bin/bash for num in {1..10}; do echo $num done 如果你运行它,你应该会看到像这样的输出: $ ./for-loop.sh 1 2 3 4 5 6 7 8 9 10 你也可以使用for num in 1 2 3 4 5 6 7 8 9 10; do,但是使用括号扩展使得代码看起来更短且更智能...
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,自...
Create a bash file named loop4.sh with the following script to find out the odd and even numbers from 1 to 5. #!/bin/bash # Define for loop in C-style format for (( n=1; n<=5; n++ )) do # Check the number is even or not if (( $n%2==0 )) then echo "$n is ...
# For loop C-style for (( i=0; i<=5; i++ )) do echo "Element $i" doneCopy The expression consists of: The initializer (i=0) determines the number where the loop starts counting. Stop condition (i<=5) indicates when the loop exits. ...
Now after running the abovefor loopcommand press the up arrow key from the terminal and you can see the multi-linefor loopis converted to a single line for a loop. Example 2 - Working with ranges You may want to run thefor loopNnumber of times, for that, you can use bash built-in...
for i in {0..20..5} do echo "Number: $i" done Over Array Elements While one can use the for loop for numbers and strings, programmers can even leverage the same to repeat over a range. For example, we will state an array - Players and iterate over each of the elements of the ...

当我们用编程语言编写一个 forloop时,我们正在构建一个迭代的命令式:我们要求计算机首先完成一个工作,然后循环到最后。但通过GNU Parallel编写命令时,我们遵循所谓的描述性功能编程。就是,我们尝试用模式描述我们想要的内容,然后让计算机填写该模式并输入完整命令。 GNU Parallel的极简介绍 GNU Parallel 是一个非常好用...
