The for loop allows you to specify a list of values. A group of statements is executed for each value in the list. For loop syntax The for loop in the shell takes a list of words (strings) as an argument. The number of words in the list determines the number of times the statements...
The following section is focusing on how to implement Bash for loops in Bash scripting. In Bash for loop is used to go over a list of objects, 6.1.1 Bash for loop Iterating Through a List of Strings: The basic Bash for loop goes over a list of elements, array, or can be used to...
run the loop while the condition is true). Theforstatement is more versatile than thewhilestatement as you can also iterate over a list of items using aforloop without explicitly defining a condition. Thusforloops are often used when the number of loop iterations or the items to ...
From the previous section, you might have understood that thefor loopaccepts a list of items. The list of items can be anything like strings, arrays, integers, ranges, command output, etc. Open the terminal and run the following piece of code. ...
Alternatively, use strings in a space separated list: #!/bin/bash # For loop with individual strings for i in "zero" "one" "two" "three" "four" "five" do echo "Element $i" done Save the script and run from the terminal to see the result. ...
我想编写一个循环遍历 15 个字符串的脚本(可能是数组?)这可能吗? 就像是: for databaseName in listOfNames then # Do something end arrays bash shell unix 答案你可以像这样使用它: ## declare an array variable declare -a arr=("element1" "element2" "element3") ## now loop through the ...
Example 1: Loop through a Given Range #!/bin/bash # Print numbers from 1 to 5 for i in $(seq 1 5); do echo $i done In the above snippet, the $(seq 1 5) part is used to generate a list of integers from 1 to 5. It will then loop over the list one by one and then ea...
Another syntax variation of for loop also exists that is particularly useful if you are working with a list of files (or strings), range of numbers, arrays, output of a command, etc. The list/range syntax for loop takes the following form: ...
BASH script under linux supports the for loops. There are quite a few ways to write for loops. 1. List the Values for I in 1 2 3; do echo $I; done 2. Use 'SEQ' to list the values (but depreciated) for I in $(seq 1 3); do echo $I; done # or seq(1 1 3) 3.
