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 for n in {1..10} do if [[ $n -eq '6' ]] then ...
Thecontinuestatement exits the current iteration of a loop and passes program control to the next iteration of the loop. In the following example, we are iterating through a range of numbers. When the current iterated item is equal to ‘2’, thecontinuestatement will cause execution to return...
Bash For Loop To Iterate Over a Range We can use for loop to transverse values of a range. In Bash, the range can be created by using the curly braces, so we passed the range in the loop, and the loop iterate till the max value of the range. Here, the range includes 0 to 5 v...
[Bash] for loop The basic syntax of a for loop in Bash is: forvariableinlistdocommandsdone Examples Example 1: Iterating Over a List of Words #!/bin/zshforwordinapple banana cherrydoecho"The word is:$word"done Example 2: Iterating Over a Range of Numbers...
for loop with range You can also use the optional increment parameter which will do step-wise increments. Take a look at the below snippet where the increment of three is given. This will generate the sequence from one and do a step increment of three until the end value ten. ...
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.
In the following example, we specify the first set for the range of IPs and define the range using a “for” loop. In the “do” section, we set it to execute the “ping” command for each iteration in the range. Watch how we use the Bash “for” loops to automate the process an...
This type of for loop is characterized by counting. The range is specified by a beginning (#1) and ending number (#5). The for loop executes a sequence of commands for each member in a list of items. A representative example in BASH is as follows to display welcome message 5 times wit...
$ bash forloop5.sh Here, the alphabets, ‘B’, ‘L’ and ‘S’ found in the text, “Bash Scripting Language”. So, three lines of output are printed. Example-6: For loop to read a range with the increment The example shows how you can use ‘for’ loop to find out all even nu...
“ 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...
