Example-3: For loop with continue statement ‘continue’ statement is used inside the ‘for’ loop to skip any statement based on a particular condition. Create a file named‘forloop3.sh’ with the following script. Here, a variable named $courses is used to assign a text value. ‘for’...
In the for loop, we can use the continue statement to skip its execution. You can see the loop prints all the values except 3 because when it reaches 3 then due to the continue statement it skips execution and resumes with the next iteration that is 4. for ((i = 0 ; i <= 5 ; ...
“ 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...

Bash For Loop 示例 1. 解压所有 Zip 文件 以下示例在根目录中查找与“*.zip*”匹配的文件列表,并在该 zip 文件所在的相同位置创建一个新目录,并解压缩该 zip 文件内容。 # cat zip_unzip.sh #! /bin/bash # Find files which has .zip for file in `find /root -name "*.zip*" -type f` do...

Now that we have our “for” loop created in our Bash script, save and exit the file. We must first add the executable permission to execute the script. sudochmod+x<filename.sh> Next, execute the script as shown in the following. Watch how we get the Bash “for” loop iterating the...
We can put some conditions in the body of the for loop, followed by a continue statement to skip the next body of the loop. See the example: for ((i=1;i<=5;i++)) do if [ $i == 3 ] then continue fi echo $i done Due to the if condition, the loop will skip the echo ...
Break- Exits the loop and skip any pending iterations. Continue- Skip the current iteration and pass the control back to the for loop to execute the next iteration. To check if they are bash built-in or not, usetypecommand: $ type break continue ...
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...
