In the following example code, the loop starts by initializingi = 0, and before each iteration, checks ifi ≤ 10. If true, itprintsthe current value ofiand [increments the variable]iby 1 (i++). Otherwise, the loop terminates. for((i=0;i <=1000;i++));doecho"Counter:$i"done Copy...
i=1 for word in $text do echo "Word No-$i = $word" ((i=$i+1)) done Then run the following script: $ bash forloop1.sh Example 2 - for Loop With a Break Statement The break statement is used within the ‘for loop’ to end the loop. First, create a file and run the fol...
You can run any commands that derive a list of items to be processed byfor loop. The command should be either enclosed with ticks "``" or brackets "$()". In the below example, I am running the command that will get process ID and filter the last five processes. For loop will now ...
A loop is used to repeat a set of statements repeatedly. The Bash FOR loop is the most basic type of loop, which is used for iteration. Other than this, there are two more types of loops: the while loop and the do-while loop. Imagine that you want to run a single statement multipl...
“ 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。 可以在shell提示符下或在shell脚本本身内使用for循环。 更详细信息 请看: Bash For Loop Examples In Linux for循环语法 数字范围的...

How do I use bash for loop to repeat certain task under Linux / UNIX operating system? How do I set infinite loops using for statement? How do I use three-parameter for loop control expression? A 'for loop' is a bash programming language statement which allows code to be repeatedly execu...
if [ $i -eq 4 ]then continue elif [ $i -eq 6 ]then break fi echo $i done 这将跳过数字 4 并在到达数字 6 时停止循环。通过掌握 for 循环的使用，可以更高效地在 Linux 中编写自动化脚本。这些循环在执行重复性任务时提供了一种简洁且强大的方法。参考：tecmint.com/bash-for-loop-...
for i in {1..5} do echo "$i" done In the example, the loop will echo all numbers from one to five. In addition, you can change the increment using the{START..END..INCREMENT}three-expression syntax. Here’s the code example: ...
