Using the “for” Loop To Compare a Given String With the Elements of the Array We will use the same Bash script for this scenario and extend it further. The main structure of our code will remain the same, and we will need to update the contents of the loop code. Using the same sc...
Bash Script #!/bin/bash #Array Declaration arr=("Welcome""to""Javatpoint") fori in"${arr[@]}" do echo $i done Output For Loop to Read white spaces in String as word separators The syntax can be defined as below: #!/bin/bash ...
“STRING” 将会阻止(解释)STRING 中大部分特殊的字符。后面的实验会详细说明。 单引号(’) ‘STRING’ 将会阻止 STRING 中所有特殊字符的解释,这是一种比使用"更强烈的形式。后面的实验会详细说明。 反引号(`) 命令替换 反引号中的命令会优先执行,如: cp `mkdir back` test.sh back ls 先创建了 back 目录...
for var in item1 item2 ... itemN do command1 command2 ... commandN done 例如,顺序输出当前列表中的数字: for loop in 1 2 3 4 5 do echo "The value is: $loop" done 输出结果: The value is: 1 The value is: 2 The value is: 3 The value is: 4 The value is: 5 while循环用于...
The following script creates three sample files using a for loop. Azure CLI Copy for i in `seq 1 3`; do echo $randomIdentifier > container_size_sample_file_$i.txt done The following script uses the az storage blob upload-batch command to upload the blobs to the storage container. Az...
In this example, we will use a "for loop" to output a certain string a specific number of times. You will be able to grasp the following code example easily. #!/bin/bash echo "For loop example" for i in 1 2 3 4 5 do echo "$i - Welcome" done echo "* end of script *" ...
3. Passing arguments to bash script You can pass arguments to a bash script while running it in the following manner: ./my_script.sh arg1 arg2 Inside the script, you can use $1 for the 1st argument, $2 for the 2nd argument and so on. $0 is a special variable that holds the name...
for until While Loop If you have ever programmed before in any language, you probably already know about looping and how you can use it to control the flow of a program or script in addition to the if, elif, and else. Looping allows you to iterate over a list or a group of values ...
For instance, the for ((i=0; i<5; i++)) loop will do the specified task 5 times in an iterative manner. To print the elements of an indexed array in Bash using a for loop, see the below script: #!/bin/bash #Declaring an indexed array and assigning it with values coffee=(...
done: Indicates the end of a loop block. case: Used for creating a switch statement, allowing the execution of different commands based on the value of a variable. These keywords help structure the flow of a Bash script, making it possible to perform complex tasks and automate various process...
