The script first prompts the user to input a number and checks if the input is a valid number. Then, it uses a for loop to iterate from 1 to 10 and prints the multiplication table of the input number for each iteration. 4. Write a Bash script that uses a while loop to continuously ...
to specify the iterator variable “I” after the word “for”. To mention, the range of iterations in brackets must be followed by the word “in” as per the below image. The range has been defined from 1 to 10 with two dots in between. The “for” loop will continue to run until...
for element in Hydrogen Helium Lithium Beryllium do echo "Element: $element" done CopyThe loop will produce the following output: Element: Hydrogen Element: Helium Element: Lithium Element: Beryllium Copy Loop over a range You can use the sequence expression to specify a range of numbers or ...
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...

在类Linux 下,写脚本任务经常需要通过 bash shell 循环执行固定次数或在指定数字范围,可以通过for ... in ...语句搞定。 1for ... in ... for ... in ... 如果要在指定数据范围内循环执行,示例如下: foriin{7..14}doecho$idone 如上所述,从 7 依次遍历到 14,即循环 8 次,且可以获取对应的数字...
在替换bash中嵌套的for循环时,可以使用更高效和简洁的方法来实现相同的功能。替代for循环的方法主要有两种:使用管道和使用循环构造。 1. 使用管道:在bash中,可以使用管道将多个命令连接起...
for n in {1..7}; do echo $n done Once the shell script is executed, all the values in the range are listed, similar to what we had insimple loops. Bash For Loop with Ranges Example Additionally, we can include a value at the end of the range that is going to cause thefor loop...
