HomeBackend DevelopmentPHP TutorialPerl、PHP、Python、Ruby对于入门的Linux运维来说,哪个更易学?

基础较差,刚刚入门Linux运维,希望可以学习一个用于Linux运维

回复内容:

perl太古老,写好的代码看起来费劲,现在基本停止进化了,虽然6搞了很多年了,还不知道什么时候能出来,php很呆板不适合做运维,最后就在 python和ruby这两个来抉择,很明显支持python的人会居多,主要可能是因为python的先发优势,但ruby有一个优势:一行代码解决问题的能力(这一点继承了perl),当年刚学perl非常惊讶于他的这样 perl -ne 'chomp; print;' file 简洁的连变量都不用写(多年过去只记得这一句了),ruby很好的继承了这一点 ruby -ne 'print $_.chomp' file ,还有比如吸收了awk的BEGIN/END,可以完全替代awk、sed、grep等命令,这里有些例子:Ruby one-liners,python因为必须缩进,在一行代码解决问题的能力上面明显不敌ruby,所以推荐Ruby。 Ruby,你可以参考我写的这本书:Chef之道 - GitBook 运维方向的常用语言目前主要是三种:Shell Scripts,Perl,Python。抛开shell不谈(无论你最后选哪个,shell都是绕不过的,哪怕不精通至少也要熟练)。而在Perl与Python当中,目前的选择当然是Python第一,除非你有很多Perl的历史遗留需要维护。PHP与Ruby更多的是用在WEB端的开发中,在运维体系中用的不多。

Perl 与 Python 相对 PHP 与 Ruby 的优势主要集中在现有发行版的Linux基本都自带,有极其丰富的针对运维的第三方库,有大量的实际经验可以借鉴。

而Python相对于Perl的优势在于,简单,易学,可读性好,写代码的效率高,Code review与团队间合作愉快

Python的运行效率有所薄弱,但在运维场景中,高的开发效率远比稍慢的运行效率更重要。 ruby。语法优雅 ,一致,上手比较容易,而且题主所说的linux运维方面对执行效率要求不是很高。
个人觉得python语法没有ruby优雅,上手比ruby难一点。
python开源库多,然而在这方面并没有什么卵用。 ruby和python都可以 Perl,谁用谁知道,就比比 one line 好了,其他那几个能战么( 个人经验
ruby语法简练优雅,但约定大于配置的“自由”思想需要学习者认同适应;
python数据结构处理方便,语法精炼,了解配置就好;
php接触不多,感觉编程思想有些混杂;
perl根本没兴趣去接触… 不会php, 就说剩下三个, 学习难度: python >> ruby > perl
对运维来说的实用程度: perl >> ruby/python 要知道很多金融行业的大牌公司, 都是一边骂perl难用一边打着灯笼招人来维护他们的遗留perl脚本的.

不过这又有啥关系呢? 我知道ruby一堆缺点, 但是我还是会选ruby, 这几个里面也只有ruby的设计正常一些了... 我用php做运维,也没啥不行的。php+shell各种cli,各种daemon。唯一不好的是没什么开源的软件用。另外b格跟不上py的。 要想精通都很难。
我觉得可以根据你最急的需求,选一个相对合适的语言入手,并逐步把他吃透,搞懂。然后根据一些文档或者书籍《xx天精通xx》,真正了解语言特性。
等你真的精通一门语言的时候,再去用别的语言做一些简单的工作,就可以看看《快速入门xxx》就可以干活了。


因为本质上说,很多编程语言的基础和常见特性是可以互通的,缺失的仅仅是他们的特性而已。

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AM

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values ​​and handle functions that may return null values.
