In this example, we initialize a counterindexat 0. The ‘while’ loop runs as long asindexis less than the length of thefruitsarray (obtained using${#fruits[@]}). Inside the loop, we print out the current fruit,
Alternatively, loop from ten to zero counting down by even numbers: #!/bin/bash # For loop with reverse range increment numbers for i in {10..0..2} do echo "Element $i" doneCopy Execute the script to print every other element from the range in decreasing order. Exchange increment2for...
This problem involves writing a Bash script that defines a function named "add()" to calculate and return the sum of two given numbers using a recursive approach. The function should handle the addition by incrementing or decrementing the first number until the second number is exhausted, effect...
be of the same type. When the increment is supplied, it is used as the difference between each term. The default increment is 1 or -1 as appropriate. 我只是复制了一小段,详情可以自己翻看,总之记住这个就可以了。
github_ip_ranges.sh - returns GitHub's IP ranges, either all by default or for a select given service such as hooks or actions github_sync_repo_descriptions.sh - syncs GitHub repo descriptions to GitLab & BitBucket repos github_release.sh - creates a GitHub Release, auto-incrementing a ...
1. 记录运行脚本的先决条件和主要步骤 记录,尤其是以有自述标题的单个文件(例如 "README-testing.txt")记录功能测试的主要想法是很重要的,包括,如先决条件、服务器和客户机的设置、脚本遵循的整个(或详细的)步骤、如何检查脚本的成功/失败、如何执行清除和重新启动测试。

For example, someone who may want to create a loop that prints the numbers 1 to 10 in descending order may end up creating the following infinite loop by mistake: for ((i=10;i>0;i++)); do echo $i done The problem is that the loop keeps incrementing the variableiby1. To fix it...
