每个人或多或少总会碰到要使用并且自己完成编写一个最基础的Bash脚本的情况.真实情况是,没有人会说"哇哦,我喜欢写这些脚本".所以这也是为什么很少有人在写的时候专注在这些脚本上. 我本身也不是一个Bash脚本专家,但是我会在本文中跟你展示一个最基础最简单的安全脚本模板,会让你写的Bash脚本更加安全实用,你掌握了之后肯定会受益匪浅. 为什么要写Bash脚本 其实关于Bash脚本最好的解释如下: The opposite of "it's like riding a bike&…
Numbers can be regarded as product of its factors. For example, 8 = 2 x 2 x 2; = 2 x 4. Write a function that takes an integer n and return all possible combinations of its factors. Note: You may assume that n is always positive. Factors should be gr…
